Introduction to Several Cable Ties

by http://www.fiber-mart.com

Owing to its low cost and ease of use, cables ties are ubiquitous in a wide range of telecom applications. Generally, cable ties, zip ties, or tie wraps are designed to hold items together, primarily the electric cables or wires. It is treated as a type of fastener. There are multiple types of cable ties available on the market today, such as nylon cable ties, Stainless Steel cable ties, and Velcro cable ties, etc. And each of them has their own features. So this article will introduce three common cable ties for you to select which cable ties suitable for the wire management.
Nylon Cable Ties
The common zip ties, normally made of nylon, has a flexible tap section with teeth that engage with a pawl in the head to form a ratchet so that as the free end of the tape section is pulled the tie-wrap tightens and does not come undone. The Nylon material possesses an outstanding balance of properties, combined strength, moderate stiffness, high service temperature, and a high level of toughness.

Nylon cable ties are particularly resistant to repeated impact. They have a low coefficient of friction, and excellent abrasion resistance. But they should be stored in cool dry areas, out of direct sunlight, and sealed in the original packaging material. These measures will extend cable tie performance levels indefinitely. Nylon cable ties can be broadly divided into several cable ties: Colored Cable Ties, ID Marker Ties, Eyelet Cable Ties, and Releasable Cable Ties. An article entitled “Nylon, Velcro and Stainless Steel Cable Ties” has provided some detailed information about these cable ties.
Velcro Cable Ties
Velcro Cable Ties is made of soft hook and loop material, also known as hook and loop cable ties. They deliver reliability by protecting against over-tension of high-performance fiber and copper cables. These ties are adjustable, releasable, and reusable to effectively support frequent moves, adds, and changes (MACs). Moreover, a wide range of designs, sizes and colors provide flexibility and an aesthetically pleasing appearance. The key benefits of velcro cable ties are reliability, scalability and aesthetics. Velcro cable ties are very useful for computer and other data-cables as they will not crush the cables and cause damage.

Stainless Steel Cable Ties
The stainless steel cable ties either naked or coated with a red plastic, cater for exterior application and hazardous environments. This type of cable ties are made of stainless steel, which makes them much stronger and able to achieve a tensile strength of up to 400 pounds or more. Differ from plastic cable ties, you don’t need to pull this cable tie to a tight close but through a through a self-locking mechanism. This mechanism can stand alone or be part of a ball lock system. What this locking mechanism does is add strength to the tie and ensure that it doesn’t wear down or corrode when the temperatures get too hot or cold. The best part about this locking device is that you don’t need much strength to feed the tie through. Stainless steel cable ties are ideal for applications that require a high-level of protection against corrosion and environmental conditions, which may cause typical nylon cable ties to disintegrate.
stainless-steel-cable-ties
At the end of this article, one misunderstanding about cable ties needs to be explained. Cable ties, especially the plastic cable ties are generally viewed as single-use devices; they are typically cut off rather than loosened and reused. However, if a closed loop needs to be opened again, rather than destroying the cable tie by cutting, it may be possible to release the ratchet from the rack. While some cable ties are designed for reuse with a tab that releases the ratchet, in most cases a sewing needle or similar object will need to be interposed between the ratchet and the rack. Ties reused in this way will be weaker than new ones.
Conclusion
To sum up, this article has briefly introduced three cable ties. Each should be suitable for the unique applications. No matter what your installation requires, fiber-mart.COM is sure to have the exact zip or cable tie that you need. Please don’t feel hesitate to contact us.

How to Create More Capacity in Data Center

by http://www.fiber-mart.com

With the ever-increasing demand for more computing power and data center servers, data center manager have the responsibility to chart a data center capacity plan and determine what strategy will accommodate business needs best. Of course, they could just expand to large facilities (upgrading to the advanced switch and fiber enclosures). However, not all IT budgets are increasing, and many users just cannot afford the extra money. Therefore, people are turning to high-density and cost-effective infrastructures. To support these applications, this article will introduce a broad selection of high-density connectivity and high capacity cable management devices.
High-Density Patch Panels
High-Density (HD) fiber patch panel solution is the most convenient approach for solving the problem of limited capacity in a data center environment. And it provides a flexible way to connect devices of different generations of equipment quickly and easily. HD patch panels consist of a panel enclosure and modular HD cassettes, which can connect a fiber network feed (via multi-strand or MTP cable) and segment it into standard LC connections in order to interface with 10Gbps devices. The following image shows a fiber adapter panel with 12 LC duplex single-mode adapters.
fiber-adapter-panel-with-12-lc-duplex-os2-singlemode-adapters
HD fiber patch panels feature the following advantages:
Flexibility: They can connect different generations of equipment such as 10Gb, 40Gb, 100Gb in a simple panel-cassette system with different connector types.
Ease of Installation: No tools are required to install the cassette in the panel enclosure. Each cassette features factory terminated connectors that reduce the time and labor required of field connector terminations.
Cost-Effectiveness: High-density and ease of installation provide a low initial investment cost. Flexibility, adjustability and reliability provide a high ROI. What’s more, network reconfiguration is highly adjustable due to the modular cassette system.
High-Density Patch Cords
As cabling density increases along with the deployment of higher network speeds, HD patch cords deliver a robust design to withstand the rigorous of daily use. Cables that can offer a smaller overall diameter improve cable management by installing in dense patch cord trays that take up less space. They also provide better airflow to maintain consistent operating temperatures, reducing the likelihood of failure or downtime.
finger-access-for-high-density-cabling
Finger access to each patch cable, furthermore hinder the cable management and makes the cable installation become more difficult. To ensure easy access, high-density patch cords are easy to remove through the use of a flexible pull-tab fiber optic cable just as seen in the above picture. This cable type has the same component and internal structure as the traditional patch cords (e.g.SC FC patch cord), except the a tab attached to the connector, which makes it easy for cable management. These tabs can help increase cabling density and maintain reliability, preventing you from accidentally loosening surrounding connectors as you access the patch cord you need.
MPO/MTP trunk cable is the another example of the HD patch cords. These cables are the foundation of easier, faster and better pre-terminated fiber connectivity solutions, as it allows tighter trunk cable bends for slack storage and routing. With the high-density trunks in your data center solution, less space is consumed and installation is easier.
High-Density Fiber Enclosures
Fiber enclosure makes full used of the spaces in data center by combining most of the fiber optic connections in strong standards modules, providing solid protection of data center links and increasing cabling density. Therefore, data center managers can get easy access to fiber connections and easy cable management. Accordingly, the cost for data center installation and maintenance can be effectively reduced.
fiber-enclosure
Fiber enclosures are usually available in 1U, 2U, 3U, 4U. The 1U rack mount fiber enclosure is the most commonly used one on the market. Now 4U or larger rack mount fiber enclosures are also becoming popular driven by the increasing of fiber counts in data center. Except standards rack mount fiber enclosures, a lot of data centers or server rooms use customized fiber enclosures for their special requirements.
fiber-mart.COM FHD Series rack mount fiber enclosures are available in 1RU, 2RU and 4RU rack unit options. With optional FHD cassette modules or adapter panels in single-mode, multimode, or 10G multimode versions, users can install, maintain, and upgrade their cabling systems in a more flexible and cost-effective way. In addition to rack mount solution, our FHD series products also support wall mount type which can meet the cabling demands on fiber industrial environments.
Conclusion
High-density optic solutions enable data center operators to maximize the amount of active equipment and cables in a data center by minimizing the foot print of the networking infrastructure. Besides the above HD optical products, there are also a range of HD products including the high speed interconnect optics, cable assemblies, cable management hardware. If you want to know more about the HD products from fiber-mart.COM, please have a look at our website.

Cost Comparison: Fusion Splicing Versus Pre-terminated System

by http://www.fiber-mart.com

Fiber optic joints or termination is a necessary process when installing a network. Every network operators who aim to deploy a next-generation fiber network have to determine how to build a flexible, reliable and long-lasting infrastructure at the lowest possible cost. In general, there are mainly two fiber optic termination methods: splices which create a permanent joint between the two fibers, or connectors that mate two fibers to create a temporary joint. When people decide to use either method, many factors should be taken into account. Today’s article will evaluate both methods from the aspect of cost to help you choose the effective termination method.
Weighting the Two Methods
Besides the features of low loss, minimal reflectance and high mechanical strength, fiber optic termination must be compatible to the environment in which they are installed. Before we come to the cost comparison of these two termination methods, let’s firstly have a brief overview.
As it known to all that, splices create a permanent joint between two fibers, so its use is limited to place where cables are not expected to be available for servicing in the future. The most common application for splicing is joining cables in long outside plant cable runs where the length of the run requires more than one cable. There are two types of splices, fusion and mechanical. Fusion splicing is most widely used as it provides for the lowest loss and least reflectance, as well as providing the strongest and most reliable joint.
fusion-splicing
Fusion splicing machines are usually called fusion splicer available on the market that splice a single fiber or a ribbon of 12 fibers at one time. The above picture shows how to splice a fiber optic jumper. Virtually all single-mode splices are fusion. Fusion splices are made by “welding” the two fibers together usually by an electric arc. To be safe, you should not do that in an enclosed space like a manhole or an explosive atmosphere, and the equipment is too bulky for most aerial applications, so fusion splicing is usually done above ground in a truck or trailer set up for the purpose.
Today’s single-mode fusion splicers are automated and you have a hard time making a bad splice as long as you cleave the fiber properly. Fusion splicers cost thousands US dollars (up to $5,000), but the splices only cost a few dollars each. The following part display the main features of the fusion splicing:
Typical average optical losses of 0.05dB or lower
Not de-mateable
Special installation skills needed
Tools sensitive to the environment
Relatively long installation time
Standard organizer techniques required
Pre-terminated System
Pre-termination is the alternative termination method popular on the market. Cables and fibers are terminated to a connector in the factory. When carefully planned, splicing jobs for specialized technicians can be limited to the network construction phase. But provisioning, churn and network testing can be performed by technicians without specific fiber skills, because the organizers can be very simple.
With pre-connectorized products, the connection time is reduced from 20 to less than 5 minutes, including the connector cleaning step. When connecting fibers with connector technology, there is no issue of environmental sensitivity. What’s more, connectors are accessible on the outside of the network element, reducing the need to access a product and the risk of disturbing other lines. The image below shows the MPO pre-terminated cables.
mpo-per-terminated-system
Factory pre-termination is also compatible with optical budget requirements by selecting the appropriate grade as defined by the international IEC standards. When properly planned, pre-connectorized
products do not add extra connectivity points, thus eliminating extra optical loss or reflections. In all, the most obvious features of the pre-terminated system lies in the following part:
Typical losses of 0.15dB or less
Fully de-mateable
No special installation skills required
Reduced installation time
Very simple organizer systems
Insensitive to environmental conditions
Cost Comparison
The start-up costs for the fusion splice are significantly higher, as fusion splicers can be very expensive. Even the cheapest fusion splicer will cost nearly $2,900 (fiber-mart-F600 Fusion Splicer from fiber-mart.COM) more than the most expensive crimp kit. Not counting the initial start-up costs, splices will run anywhere from $7.20 to $8.25 per splice, which is much lower than the pre-terminated connector. The following image shows the vivid comparison between fusion splicing and pre-terminated system.
pre-terminated-vs-fusion-splicing
As for the pre-terminated connector, the most significant advantage is the wire management hardware involved. A pre-terminated connector requires no additional hardware over a standard connector. And it is faster to terminate a crimp connector, saving labor time ($0.75 per splice), and splicing also requires additional material costs in the form of splice protectors ($0.40 per splice). Fiber splicing technicians have specialized training that makes them expensive when compared to someone simply pling things in. The additional material and closet space for managing splices can cost an additional $6.05-7.10 per connector. But with a little careful planning as to lengths of fibers needed, pre-terminated fibers can be installed quickly and with no training.
In all, fusion splicing makes a lot of sense for trunk fibers and locations where there are anywhere from 48 to 192 fibers to splice. In the drop locations, where there may be only one or two splices at each location, the setup time for each location may negate any cost savings from fusion splicing.
Making the Choice
In comparing pre-termination and fusion splicing, both have their inhered advantages. Fusion splicers offer many advantages in the premises environment, from being lightweight and compact to operating on a battery. These new units minimize setup time and are ideal for use in locations where space is tight. In addition, the total splice and heater cycle time is less than one minute, thereby enabling technicians to move through many termination locations quickly.
However, we cannot deny the fact that the start up cost of the fusion splicing is huge, thus customers that can’t deal with budget are going to demand pre-terminated connectors. Pre-terminated solutions offer the most benefits: It’s easy to install pret-terminated cables, and because they’re available in custom lengths, it’s easy to get the exact lengths required to limit the excess slack. Many more users will rely on the pre-terminated trunk cables and sacrifice the inconvenience of dealing with slack, because it offers faster deployment.
As you get into significantly higher fiber counts, fusion splicing could save time over installing connectors. While for those who don’t have a fusion splicer or splicing experience, may want to consider pre-terminated connectors. fiber-mart.COM offers both fusion splicer and per-terminated cables, our products are integrated, holistic physical infrastructure solutions that guarantee a reliable and stable performance for your network.

In-depth Understanding of LC Duplex Connectors

by http://www.fiber-mart.com

As one of the small form factor (SFF) field polish connectors, LC duplex connectors are widely used for equipment cross-connects or interconnects in backbone, horizontal and work area applications for high-speed data transmissions. They provide a solution for high-density telecommunication rooms, LANs (Local Area Networks), public networks and fiber-to-the-desk applications. While talking about LC duplex, most just think them as the small useful tools which allow fast and easy field termination for fiber optic connectivity. Actually, LC duplex are more than what their design and appearance show. Their world are full of colors. This article guides the inner world of these LC duplex connectors from their several family members.
Standard LC Duplex
It’s known that the standard LC connector is developed by Lucent Technologies. Its connector body is squarish shape that is similar to SC connector, and has half the size of the SC. Standard LC duplex connectors are LC with a duplex configuration with a plastic clip. The fibers used to terminate in its 1.25mm ceramic ferrule can be both single-mode and multi-mode versions, such as LC to LC fiber patch cable single mode and LC LC multimode patch cord. Compared with SC, LC’s high-density design and 1.25mm ferrule double the port density, reducing space requirements on racks, enclosures, panels and faceplates. Nowadays, LC duplex connectors are still popular both in telcos and high bit rate LANs, etc..
Mini-LC Duplex
As a variation of standard LC duplex, the mini-LC duplex uses current industry-standard LC connectors, but allows closer ferrule spacing by using the duplex clip (usually with color coding)—mini-LC has a reduced center spacing of 5.25mm compared to a standard LC of 6.25 mm. This type of LC duplex connector is designed to operate with the Mini SFP modules and provide a higher density deployment for data center equipment.
LC Duplex with Uniboot Uniboot
LC duplex connector with uniboot is two LC connectors encased in a common housing with one boot, terminated on a single twin-fiber round cable. This type of connector is more compact compared to standard LC duplex. Fiber patch cables terminated with uniboot LC duplex connectors, are ideal for high-density cabling application since they reduce more fiber counts and greatly reduce cable management space. (The boots of an LC duplex connector can be configured with various versions according to different requirements. In addition to standard connector boots and uniboots, there are mini boots, BTW (Behind the Wall) boots, short boots, and 45 or 90 degree angel boots in the market.)
LC-HD Duplex
In practical operation, it’s not easy to release the LC duplex connectors in patch panels, and sometimes thumbs and forefingers are not ideally suited to operate the release lever and pulling the connector. As such, LC-HD duplex connectors are designed to help deal with this issue. With a flexible “pull-tab” or “push-pull tab”, the LC-HD duplex connector can be disengaged easily from densely loaded panels without using the special tools which allows users easy accessibility in tight areas when deploying in data center high-density applications. Some types of LC-HD duplex connectors combine the advantages of uniboot, which make them more suitable to high-density cabling applications.
Keyed LC Duplex
Keyed LC duplex connectors are available in 12 colors, thus creating a colorful LC world. Each color of the keyed LC duplex connectors represents a unique keying pattern which only allows its matched color-coded adapter mating. This kind of LC duplex connector can help segregate or identify of parts or paths within a network infrastructure, as well as reducing the risk of accidental or malicious network access, particularly in shared access areas or in secure hierarchical environments.
LC Duplex Connector Advantages
The LC duplex connector is designed in response to the growing needs for smaller and easier-to-use fiber optic connectivity. It simplifies moves, adds, and changes, and reduces installation time for field mountable connectors, time- and money-saving. Additionally, it doubles fiber density in shelves and outlets –lowering system costs again, as well as improves durability and reduces cross-connect rearrangement effort.
Conclusion
LC duplex connector uses an improved version of the familiar and user-friendly telephone plug, which provides a reassuring, audible click when engaged. The unique combination of small size and the click of connectivity makes the LC duplex the right choice for your network. With the increasing connectivity requirements. The family LC duplex connectors are sure to be enlarged. When you want to buy these connectors, fiber-mart is a good choice for many LC solutions. Besides LC solutions, SC solutions are also available for you,like SC patch cord, SC adapters, and so on. Visit fiber-mart for more information about LC and SC fiber optic solutions.

40G QSFP+: Data Center Bandwidth Provider

by http://www.fiber-mart.com

With time passing by, the world’s data centers witness the rapid flowing of digital information whose volume grows at an ever increasing rate. The increase of server virtualization and cloud computing applications, coupled with the trend toward network convergence, all these are boosting today’s data center networks to become faster and more efficient than ever before. Date back to the past years, 100Mbps Ethernet is replaced by 1Gbps Ethernet which is then substituted by 10Gbps Ethernet. With 40GbE and 100GbE being available in the market, some companies or organizations can implement cut-through switching and flatter network architectures which can deliver more bandwidth, so as to reduce traffic latency and meet wireless computing needs.
To ensure the smooth 40GbE networking performance, one device is fundamental—40G QSFP+ (Quad Small Form-factor Plable Plus) transceiver. This QSFP+ transceiver interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic cable, providing sufficient bandwidth to enable fully non-blocking switch fabrics.
40G QSFP+ Working Principlerinciple
40G QSFP+ transceiver is a hot-swappable module, integrating 4 independent 10Gbps data lanes in each direction for 40Gbps aggregated bandwidth. QSFP+ modules offer customers a wide variety of high-density 40Gbps connectivity options for data center, high-performance computing networks, enterprise core and distribution layers, and service provider transport applications. The release of the IEEE 802.3ba physical layer standard for 40G QSFP+ in 2010 specifies both fiber and copper cabling solutions, such as 40GBASE-SR4, 40GBASE-LR4 and 40GBASE-CR4.
40G QSFP+ Port types
Commonly used QSFP+ transceiver port types are 40GBASE-SR4 and 40GBASE-LR4.
40GBASE-SR4
40GBASE-SR4 physical medium dependent (PMD) variant defines a 4 lane parallel optical interconnect for operation up to 100m link length over OM3 multi-mode fiber (MMF) and to 150m over OM4 MMF. It establishes high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP multi-fiber female connectors. Four of the twelve fiber for receive, other four for transmit, leaving the middle four fiber unused. Each of the four lanes operates at a data rate of 10.3125Gbps which is the same serial bit rate that was defined for 10Gb Ethernet links in the IEEE 802.3ae standard ratified in 2002.
40GBASE-SR4 PMD addresses the modern need for 40Gbps interconnects in the data center and takes advantage of lower cost 850nm Vertical Cavity Surface Emitting Laser (VCSEL) technology that is widely deployed throughout networking industries. As each of the 4 lanes in 40GBASE-SR4 operates at the same serial bit rate as a 10Gb Ethernet link, there is an opportunity for switching hardware vendors to utilize 40GBASE-SR4 as 4 separate 10Gb Ethernet interconnects. The problem is that 40GBASE-SR4 standard is not defined to be backward compatible with the existing 10GbE short reach interconnect standard.
To address this issue, QSFP BiDi transceivers have been released into the market. A QSFP BiDi transceiver (e.g. Cisco QSFP-40G-SR-BD) transmits full-duplex 40-Gbps traffic over one dual-fiber LC-connector OM3 or OM4 MMF cable. It provides the capability to reuse 10-Gbps fiber infrastructure. In other words, it enables data center operators to upgrade to 40-Gbps connectivity without making any changes to the previous 10-Gbps fiber cable plant.
40GBASE-LR4
40GBASE-LR4 has two link options: coarse wavelength division multiplexing (CWDM) and parallel single-mode fiber (PSM). This passage mainly talks about the first one option.
40GBASE-LR4 CWDM QSFP+ uses a duplex LC connector as the optical interface, able to support transmission distance up to 10km over single-mode fiber (SMF). It converts 4 inputs channels of 10G electrical data to 4 CWDM optical signals by a driven 4-wavelength distributed feedback (DFB) laser array, and then multiplexes them into a single channel for 40G optical transmission, propagating out of the transmitter module from the SMF. Reversely, the receiver module accepts the 40G CWDM optical signals input, and demultiplexes it into 4 individual 10G channels with different wavelengths. The central wavelengths of the 4 CWDM channels are 1271, 1291, 1311 and 1331 nm as members of the CWDM wavelength grid defined in ITU-T G694.2. Each wavelength channel is collected by a discrete photo diode and output as electric data after being amplified by a transimpedance amplifier (TIA).
Cable Types for 40G QSFP+
IEEE has specified standards for 40G transmission in both long distance and short distance, which are 40GBASE-SR4 and 40GBASE-LR4. As what has been mentioned above, the latter is sested for 40G transmission over SMF in long distance up to 10km, while the former is for 40G transmission in short distance over MMF (often in with a 12-fiber MPO connector version)—OM3 (up to 100 meters) and OM4 (up to 150 meters). OM3 and OM4, which are usually aqua-colored, are accepted economic solutions for 40G in short distance with lower insertion loss and higher bandwidth. Besides, DACs are also chosen as the 40G cabling solutions sometimes, available in QSFP+ to QSFP+ DAC and QSFP to SFP+ cable versions.
Conclusion
40G QSFP+ transceivers support 40GBASE Ethernet, allowing flexibility of interface choice and great bandwidth for data centers. For your smooth 40GbE performance, fiber-mart supplies various cost-effective QSFP+ transceivers which are fully compatible with major brands, such as Cisco, Juniper, Brocade, and so on. Besides these 40G modules, SFP transceivers are also offered, like Cisco GLC-T, a Cisco compatible 1000BASE-T SFP. All these products are rigorously checked for quality and compatibility assurance. If you want such a module for your networking use, you can consider fiber-mart.

Understanding Industrial Fiber Optic Cable

by http://www.fiber-mart.com

Fiber optic cabling usually utilizes redized jackets to ensure optimal performance in the face of extreme temperatures; exposure to UV/sunlight, oil, and solvents; and crushing impact, which makes it the ideal solution in any industrial environment where high-speed, high-bandwidth data solutions are needed. It can be used for campus and in-building data backbones to anchor an operation’s Ethernet, and also for point-to-point digital signal transmission. Today’s article will make a brief introduction to the basics of industrial fiber optic cable.
fiber-optics-fiber-mart-com
The Advantages of Fiber Optic Cable
Compared to the conventional copper wires, fiber optic cables are smaller and lighter than copper cables, extremely durable and intrinsically safe, with no risk of spark hazards. In addition, the following part lists several detailed information about the benefits of fiber optics.
Higher carrying capacity—as the fiber optic cables are thinner than copper cables, more fibers can be bundled into a given-diameter cable. This allows more data information will be be carried across the network without interruption.
Less signal degradation—it is known that the loss of signal in optical fiber is less than in copper wire.
Lightweight—An optical cable weighs less than a comparable copper wire cable. Fiber-optic cables take up less space in the ground.
Flexible—Because fiber optics are so flexible and can transmit and receive light, they are used in many flexible digital applications.
Types of Fiber Optic Cables
Fiber optic cabling can be segmented based on design criteria and installation environment:
Loose tube cables lay thinly coated fiber strands into unitized thermoplastic tubes, giving the fiber strands flexibility to move within the tubes and the cable, which makes it possess the ability to stand up to outdoor temperatures and harsh environments. Although loose-tube gel-filled fiber optic cables are used for high-fiber-count, long-distance telco applications, they are an inferior design for the Local Area Network applications where reliability, attenuation stability over a wide temperature range and low installed cost are the priorities.
loose-tube-or-tight-buffered-cable
Tight buffered cables contain an individual buffer on each fiber stand, allowing for easy handling and quick termination. For common small fiber counts, this design delivers a smaller cable diameter than loose tube cables and is best suited for indoor environments. The most common designs for tight buffered cabling are distribution and breakout. For applications like moderate distance transmission for telecom local loop, LAN, SAN, and point-to-point links in cities, buildings, factories, office parks and on campuses. Tight-buffered cables offer the flexibility, direct connectability and design versatility necessary to satisfy the diverse requirements existing in high performance fiber optic applications.
Singlemode and multi-mode cables are another common types of fiber optic cables. Single-mode fiber strands are designed to interface with laser optic light sources for distances beyond 300 meters, while multi-mode strands or MM fiber patch cords are designed to interface with LED and vertical-cavity surface emitting laser (VCSEL) light sources for short-distance cabling runs.
Considerations When Installing Fiber Optic Cables
If you are considering using fiber optic cables in your installation, take a moment to review the installation guides. Firstly, for industrial installations, it is critical to consider and evaluate the environment. Additionally, as the fiber optic cables are more susceptible to damage during the stress of installation, therefore there are two specifications for bend radii—Bend Radii before installation and Bend Radii after installation. All hardware and support structures should follow the recommendations of TIA-569 and NECA/BICSI 568 Standards documents. Last but not the least, use cable management straps or cable ties to support cable bundles. Make sure these implements are fastened snugly, but not tightly around cable bundles.
Conclusion
There is without saying that the advent of fiber optic cable solutions has been one of the best things to happen to technology in recent years. With the demand on technology ever-increasing, fiber optic cables are becoming the preferred method of transmission over traditional coaxial solutions. fiber-mart.COM offers a full range of optical devices, such as fiber optic cable, optical transceivers, DAC/AOC cables and so on.
