24-Port Gigabit Switch Selection

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

An Ethernet switch acts as a bridge to connect different parts of a network together. Although many routers also possess the network switching capabilities and multiple Ethernet ports, the Ethernet switch is not the replacement for routers. It is worth emphasizing that Ethernet switches are smarter than routers in that they operate at the data link layer (Layer 2) and the network layer (Layer 3) of the OSI Reference Model and therefore support any packet protocol. Ideally, switches will make better use of bandwidth if you prefer wired to wireless connections but have more devices than available Ethernet ports. On the other hand, an Ethernet switch is a costly way to expend the network in home or small business. So it is very important to invest an Ethernet switch with the appropriate number of ports to fit your needs. In the midst of various Gigabit Ethernet switches, a 24-port switch is considered as the most common Gigabit switch that connect devices in a local area network. Then this article will explore how to select a suitable 24-port Gigabit switch.
Cisco SGE2000P comes with 24 10/100/1000BASE-T RJ45 ports and 4 shared Gigabit SFP slots. This 24-port Gigabit managed switch can provide ACL (access control lists), DoS (denial-of-service), VLAN and IEEE 802.1X port authentication. And the enhanced quality of service (QoS) and traffic-management features help ensure clear and reliable voice and video communications. This Gigabit network switch enable you to take advantage of the comprehensive feature set for a better-optimized, more secure network.
TP-Link TL-SG1024 24-Port Gigabit Switch
The TP-Link TL-SG1024 features 24 Gigabit Ethernet ports and non-blocking switching, which can provide large file transferring and also be compatible with 10Mbps and 100Mbps Ethernet devices. Moreover, this network switch has 48Gbps switching capacity with 8K MAC address table, 10KB Jumbo Frame and 4MB buffer memory. This TP-Link switch is a fanless rack mount design with LED diagnostic lights, so you can easily tell which ports are in use. It can automatically adjust power consumption according to the link status to limit the carbon footprint of your network. The price is $69.99 on Amazon. So this fanless Ethernet switch is good for your wallet both because it is inexpensive to buy and because of its energy-saving technology.
Comparison of 24-Port Gigabit Switch
From the chart we can see, all the Gigabit switches listed above provide 24 port Ethernet RJ45 ports, only fiber-mart S3800-24F4S 24-port Gigabit switch has 4 SFP+ uplink ports. They have some characteristics in common that make them suitable for being used in places like home or small business office. In terms of the power consumption, TP-Link TL-SG1024 and NETGEAR ProSafe GS724T are lower than others, but the huge price spread exists between these two switches because NETGEAR ProSafe GS724T has another two SFP ports for more flexible application. Among these four switches, if you have no limited cost budget, fiber-mart S3800-24F4S is a good choice. It has more flexible port combination and higher switching capacity, that is why it may cost a little more than the other three switches. If you need stronger data transferring capability, fiber-mart S3800-24F4S is a better choice considering its forwarding rate. On the contrary, TP-Link TL-SG1024 is the best budget choice. If you want a fanless switch, NETGEAR ProSafe GS724T is an inexpensive and reliable choice, but the install program only works on Windows and the secure management is very difficult to be enabled.
Conclusion
When choosing a Gigabit Ethernet switch, the first factor to consider is how many devices need to be networked together. Purchasing a network switch with too few ports and not enough capacity will prove ineffective, and one that is too large can be a waste of money. Generally, small offices with a few employees should start with a 16-port switch, but a business that is looking to expand its operations soon needs a 24-port switch. So 24-port Gigabit switch is the most future-proofing and cost-effective choice in small business network.

 

Understanding GPON OLT / ONU / ONT SFP Module

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

Since the advances in Ethernet technology, “last mile” connectivity is expected to realize between the network backbone and local area networks (end users). Gigabit Passive Optical Network (GPON) is a cost-effective point-to-multipoint access network, which brings great improvement in data transmission distance (up to 20km) and bandwidth (an downstream capacity of 2.5Gbit/s and an upstream capacity of 1.25Gbit/s ). However, GPON’s higher bandwidth and split ratios are only achievable by using GPON-capable optical transceivers. It is well positioned to help meet the needs for higher bandwidth in FTTx applications, and continues to fuel growth in demand for GPON SFP modules. So this article will introduce the basics of GPON SFP, including GPON OLT, GPON ONU and GPON ONT SFP module.
GPON SFP is a new higher-speed bi-directional optical transceiver, which can deliver 2.5 Gbits/sec of bandwidth. And it is a kind of single fiber transceiver which comes with SC connector and can transmit data up to 20km. In addition, it features a 28-dB optical loss budget to enable 1:64 split ratios and provides adequate optical loop lengths. Most EPON and some BPON systems deployed today use 25-dB optics, which limit the split ratio and loop length. For this reason, GPON transceiver enjoys the added advantage of industrial demand. The key performance advantage is to reduce the upstream split loss arising from utilizing the mode-coupled-receivers (MCR) in a PON application. Moreover, this innovative module dose not outweigh the costs over a standard module. For these two reasons, the GPON SFP modules are very attractive to the network operators to improve the utilization of GPON network. On top of that, GPON SFP transceiver is an essential part of GPON system which is necessary both for optical network unit (ONU) installed at the subscriber’s premises and for the optical line terminal (OLT) at the central office (CO). The following part will respectively introduce the GPON OLT, GPON ONU and GPON ONT SFP module.
GPON OLT SFP Module
GPON OLT SFP is designed for OLT side in GPON network. OLT is a equipment integrating L2/L3 switch function, which is located in central office (CO). The main function is to control the information float in both directions: upstream and downstream. The GPON OLT module plays an inevitable role in the upstream and downstream transmission. In order to put across the transmission process, the downstream transmission is taken as an example. A single mode optical fiber coming from OLT (at the central office) PON port, runs to the passive optical splitter (POS) located near end users. And then the optical splitter will divide signals into separate paths which can provide service up to 64 end users. In this basic GPON topology, a GPON OLT module is used to connect a single-mode fiber patch cable to a passive optical splitter. Therefore, GPON OLT transceiver works to get the data, voice and video traffic from metro network or from a long-haul network.
GPON ONU/ONT SFP Module
Since the ONU and ONT are deployed at customer’s premises, they are connected to the OLT by means of optical fiber and no active elements are present in the link. In GPON network, the ONU/ONT transceiver is the physical connection between the customer premises and the central office OLT. This type of modules gets the signals from OLT, so they have the opposite characteristic of GPON OLT transceiver, incorporating a high performance 1310nm burst mode DFB transmitter and 1490nm CW mode APD receiver. By being pled into advanced “triple play” (data, voice & video) ONT or ONU equipment (with SFP ports), such as Ethernet switches, routers, DSLAMs or home gateway, ONU/ONT SFP module fits seamlessly into existing communications equipment and provides end users with a smooth upgrade to GPON. Therefore, GPON ONU/ONT SFP module plays an important role in the applications for point-to-multipoint (P2MP) ONT / ONU equipment in GPON network.
Conclusion
GPON SFP transceiver meets the the requirements of FTTx network to accelerate the speed or capacity. GPON OLT, ONU and ONT SFP module have their respective roles to play in the GPON networks. Many people may worry the high attenuation losses from optical splitter in the GPON networks, as above mentioned, the GPON optical module is just used to solve this problem in that it utilizes the MCR technology that protects large numbers of signals. In a word, this new module is a compelling network alternative to save cost and increase bandwidth and security.

 

MTP/MPO Fiber Cable and its Application in 40G Network

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

As the request for greater bandwidth and higher-density fiber optic connections within data centers continues, these requirements must be met by choosing the right type of connectivity. MPO/MTP fiber cable is specially designed for applications for all networking and device needs like 40G modules. It uses a high-density multi-fiber connector system built around precision molded MT ferrule, which are available in UPC and APC polish. It supports both multimode and single-mode applications, and optional lengths available. There are two main MTP/MPO cables types: MPO/MTP trunk cables and MPO/MTP harnesses cables. The following article will have a brief introduction to them individually.
MPO/MTP Standard Trunk Cables
Available in 12, 24, 48 and 72 fibers, MPO/MTP trunk cables work as a permanent link that connects MPO/MTP modules to each other. These cables are used to facilitate rapid deployment of high density backbone cabling in data centers and other high fiber environments reducing network installation or reconfiguration. A 72-fiber MPO/MTP trunk cable (see in the below image) can be terminated with 6 MPO/MTP connectors which are manufactured specifically for multi-fiber loose tube or ribbon cable. The MPO/MTP Trunk cable is designed for Data Center Applications.
72fiber-om4
These cables can interconnect cassettes, panels or redized MPO fan-outs, allowing for the flexibility in case any decision is made to change the connector style in the patch panels, new cassettes can be installed with the new connector style on the cross-connect side of the patch panel without having to change the connector on the cable trunk.
fiber-mart.COM offer single-mode (OS2) and multimode (10G OM3, 10G OM4) MPO/MTP Cable. Single-mode MPO/MTP cable is primarily used for applications involving extensive distances, 10G MPO/MTP cable provide 10G data transfer speeds in high bandwidth applications and they are 5 times faster than standard 50um fiber cable. Work with both VCSEL laser and LED sources, that means, the MTP/MPO trunk cables also provide 40G/100G MPO/MTP trunk cable.
MPO/MTP Harnesses Cables
The MPO/MTP Harnesses cable is MPO/MTP on one end, with single-fiber connectors on another end, single-fiber connector interface available in SC, ST, LC, MTRJ in forms of simplex or duplex channeling. It provides a reliable, cost-effective cabling system for migrating from legacy 10G to higher speed 40G/100GbE. They are suitable for many device needs like 100G modules, including CFP, CFP2 and CFP4 series. MPO/MTP Harnesses cable are available in SM (OS2), MM (OM3/OM4). You could select the suitable fiber according to your own needs with the selection of 12/24/72 fiber cores. The following picture shows the OS2 Fiber Optic Harness Cable.

The MPO/MTP harnesses cable application for data centers requiring quick infrastructure deployment with extended reach that want to maintain bandwidth throughout the infrastructure, its design cater for up-scaling needs and future technologies growth, it’s the best solution, which covers all fiber optic cabling needs in all areas of Data Center.
High-density MTP/MPO Cables for 40G Connection
IEEE 802.3ba 40 Ethernet Standard was ratified in June 2010. This standard specifies MPO connectors for standard-length MMF connectivity. MMF employs parallel optics using MPO interconnects for 40GbE transmission. More specifically, 40G is implemented using eight of the twelve fibers in a MPO connector. Four of these eight fibers are used to transmit while the other four are used to receive. Each Tx/Rx pair is operating at 10G.
Figure 1 shows a Type B MTP female trunk cables for 40GBASE SR4 QSFP+ and multi-fiber migration networks.

Fiberstore MPO-based fiber cabling solutions provide a fast, simple and economical way for 40G applications. Certainly, 40G fiber cabling solutions are not only limited to MPO/MTP fiber cables. QSFP cables, especially direct attach copper cables are also recommended. 40G direct attach cable provides a cost-effective solution for high-density network connectivity. You can see the detailed information in an article entitled “40G Direct Attach Cable (DAC) Cables Ovrview”.
Conclusion
To sum up, MPO/MTP cabling have proven to be an excellent solution for delivering 10G, 40G and 100G transmission, especially within a data center environment. It provides a flexible, high density option for quickly connecting services. fiber-mart.COM offers various high-density MPO/MTP fiber optic cables, trunk and harness versions, patch cords, and cassette module.

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
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.
