Data centers are never ceased their steps to bring greater speed and efficiency to telecommunication and datacoms industries. An enormous amount of data is transmitted, gathered and analyzed everyday, all which requires a vast number of high-bandwidth interconnections between data centers, and people. During these interconnections, fiber optic cables see their heaviest use.

Fiber optic cables can deliver more bandwidth for voice, video and data applications, and carry thousands of times more information than copper wire. With fiber optic cables, reliable and secure data transmission is ensured. Fiber optic cables are available in single-mode and multi-mode versions based on transmission mode standard. This article puts its focus on the latter version: multi-mode fiber (MMF), discussing MMF from its core size attenuation, bandwidth and manufacturing ways.

MMF: Larger Core Size

It’s known that MMF has a much larger core size and cladding diameter, whose different types are distinguished by jacket color: for 62.5/125 µm (OM1) and 50/125 µm (OM2), orange jackets are recommended, while aqua is recommended for 50/125 µm “laser optimized” OM3 and OM4. MMF’s larger core endows it greater light gathering capacity, allowing multiple modes of light to propagate through the fiber simultaneously. Thus, MMF is more suitable for relatively shorter-reach application, usually less than 600m. When it’s deployed in GbE applications, the maximum reach is 550m in combination of 1000BASE-SX SFP.

MMF: Attenuation/Signal Loss

Attenuation refers to the reduction of signal loss when light travels through the fiber optic cable, which is measured in decibels per kilometer (db/km). Insertion loss is the total attenuation from all sources plus any reflection losses over a specific fiber length. Such attenuation is often caused by absorption of optical energy by tiny impurities in the fiber such as iron, copper, or cobalt. Sometimes, the scattering of the light beam as it hits microscopic imperfections, called Rayleigh scattering can also lead to signal loss phenomenon. Attenuation problem is a commonplace in MMfiber-mart.

MMF: More Bandwidth

Bandwidth quantifies the complicated data-carrying capacity of MMF, given in units of megahertz-kilometer (MHz·km). Bandwidth behavior of MMF arises from multi-modal dispersion (multi-path signal spreading) which happens as the result of light traveling along different modes in the core of fibers. The bandwidth specification of performance of a MMF is verified through optical measurements during fiber manufacture. Actual system performance and data-rate handling rely heavily on bandwidth, affected by transceiver technology and device characteristics.

MMF: Manufacturing Ways

MMF can be manufactured in two ways: step-index or graded index.

Step-index fiber has an abrupt change or step between the index of refraction of the core and the index of refraction of the cladding. Multi-mode step-index fibers have lower bandwidth than other fiber designs.

Graded index fiber is designed to reduce modal dispersion inherent in step index fiber. This design maximizes bandwidth while maintaining a larger core diameter for simplified system assembly, connectivity and lower network costs. Graded index fiber is made up of multiple layers with the highest index of refraction at the core. Each succeeding layer has a gradually decreasing index of refraction as the layers move away from the center. High order modes enter the outer layers of the cladding and are reflected back towards the core. Multi-mode graded index fibers have less attenuation (loss) of the output pulse and have higher bandwidth than multi-mode step-index fibers.

MMF related transceivers: Multi-mode Transceivers

A fiber optic transceiver is a package, usually a pluggable module, comprising of a receiver on one end of the fiber and a transmitter on the other end. Over the years, multi-mode bandwidth specifications and measurement methods have evolved along with the transceiver technology, so as to keep up with delivery of higher transmission speeds. The combination of transceiver and fiber optic cable plays an important role in fiber’s practical link length. As for multi-mode transceivers which have larger core, they are often used in short-reach applications with 850mn wavelength. Listed below are several commonly-used multi-mode transceiver ports: 1000BASE-SX, 10GBASE-SR, 10GBASE-LRM, among which 10GBASE-SR port type enjoys widely deployment in 10GbE applications when the required distance is not so long. Take F5-UPG-SFP+-R for example, this F5 compatible 10GBASE-SR SFP+ transceiver listed in Fiberstore takes OM3 MMF as its transmission medium for 300m reach.

Besides what have been discussed above, there is also another MMF feature that comes into your mind: that is the affordability. MMF is less expensive than its counterpart single-mode fiber (SMF). Because of this, more people prefer MMF to SMF when the required distance is not so long. Thus, this big saving can be re-invented in other projects.

With the rapid advancement of fiber optic technology and trend towards optical communications, fiber optic patch cord has realized its great use in high speed data transmission networks, found in routers, fiber patch panels, media converters and even in hubs and switches. Compared to its previous counterpart, fiber optic jumper causes lower signal loss, delivers more bandwidth and carries more information, becoming more and more popular in cabling installation or upgrading between or inside buildings. Just like the transceiver modules which fall in many types based on different standards, fiber optic patch cables are also available in several kinds, including single-mode/multi-mode, simplex/duplex, MPO/MTP cable, armored patch cord, and so on. This article aims to introduce the last three useful fiber patch cords and their use.

Simplex/Duplex Patch Cables

Simplex cable, also known as single strand cables, has one fiber, tight-buffered (coated with a 900micron buffer over the primary buffer coating) with Kevlar (aramid fiber) strength members and jacketed for indoor use. The jacket is usually 3mm (1/8 in.) diameter, but some 2mm cable is sometimes used with small form factor connectors. Duplex (zipcord) cable has two fibers joined with a thin web.

Since simplex patch cord consists of only one fiber link, it’s used in such applications that only require one-way data transfer. But when the equipment can transmit and receive on two different wavelengths, simplex cable can also be considered. For example, transmit could be at 1310nm and receive could be at 1550nm. This application is found more with single-mode simplex patch cable.

Duplex patch cable is suitable for applications that require simultaneous, bidirectional data transfer. Typical applications include workstations, fiber switches and servers, Ethernet switches, backbone ports, and similar hardware.

MPO/MTP Cable

MPO/MTP cable uses multi-fiber MPO/MTP connectors for setting up high-performance data networks in data centers, so as to achieve greater bandwidth and handle network traffic requirements. Specifically, in MPO/MTP cable component, each one of the connector are used with ribbon type fiber optic cables which contain multi-fiber in one single jacket, so that MPO/MTP patch cord greatly saves space, very convenient to use. Based on single ferrule MT technology, the MPO/MTP cable assemblies are able to provide up to 72 fiber connections in a single point, reducing the physical space and labor requirement, while providing the same bandwidth capacity of a multi-fiber cable with individual fiber connector terminations per cable. MTP cables can be divided into trunk and harness versions (image below).

MPO/MTP patch cables have great use in Gigabit applications, especially in 40GbE. Often, MPO/MTP connectors terminate OM3 or MO4 to form structured cabling, serving as the transmission medium for 40GBASE optics (ie. QFX-QSFP-40G-SR4).

Armored Patch Cord

Armored patch cord enjoys all the features of standard fiber patch cord, available in single-mode and multi-mode version (shown below), except its much stronger characteristic. It won’t get damaged even it is stepped by an adult. What’s more, this kind of patch cord is anti-rodents, and when it’s utilized, people do not need to worry that the rodent animals like the rats may bite the cables and make them broken. Although armored fiber cables are strong, they are actually as flexible as standard fiber jumper cords, and they can be bent randomly without being broken.

Armored patch cable can be made with the similar outer diameter to the standard patch cable, which makes it a space-saving design. In addition, armored fiber cables can be with different jacket colors and jacket types, like OFNR. Light in weight, armored fiber patch cords can be with SC, ST, FC, LC, MU, SC/APC, ST/APC, FC/APC, LC/APC types of terminations.

The armored fiber optic patch cords are more robust designed, suitable to be deployed in FTTH projects inside the buildings. They use stainless steel armor inside the jacket to be resistant of high tension and pressure, able to resist the weight of an adult person.

Although the 40G/100G optical modules are on the very top trend for enterprise and data center for the interconnection, 10G transceiver modules are still in great demand. There are several types of 10G optical transceiver modules available for sale including the XENPAK, X2, XFP, small form-factor pluggable plus (SFP+) transceiver, of which 10g SFP transceiver (due to its small size and low power) is the most popular type for 10G network. According to the 10 Gigabit Ethernet standard, SFP+ transceiver can be classified into many categories: 10GBASE-SR SFP+, 10GBASE-LR SFP+, 10GBASE-ER SFP+, and 10GBASE-LRM SFP+. This article will focus on the introduction of the 10GBASE-LR SFP+ and 10GBASE-LRM SFP+ transceivers.

10GBASE-LR SFP+

10GBase-LR can support up to 10km over single-mode fiber and uses 1310nm lasers. There is no minimum distance for LR, either, therefore it is suitable for short connections over single mode fiber too. The Cisco 10GBASE-LR module supports a link length of 10 kilometers on standard single-mode fiber (SMF, G.652). FS.COM compatible 10GBASE-LR SFP+ transceiver possesses the same function as the original one with a much lower price than Amazon and ebay. The following image shows a Cisco Compatible SFP-10G-LR SFP+.

10GBASE-LRM SFP+

10GBASE-LRM still uses the 1310nm lasers, but it can only reach up to 220m over standard multimode fibers. The 10GBASE-LRM can be packaged in XFP and SFP+ form factors. FS.COM Cisco SFP-10G-LRM Compatible 10GBASE-LRM SFP+ supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (OM3/OM4). Every transceiver is individually tested on a full range of Cisco equipment and passed FS.COM’s testing with 100% compatibility. The following image shows a Cisco Compatible SFP-10G-LRM SFP+.

Contrast Between 10GBASE-LR and 10GBASE-LRM SFP+

At the first glimpse of the two terms—10GBase-LR and 10GBase-LRM, people usually have the misconception that they are similar with each other. In fact, 10GBase-LR and 10GBase-LRM meets different demands just as described in the above article. SFP-10G-LR optics (compatible with 10GBase-LR) supports a link length of 10km on standard single-mode fiber (SMF). SFP-10G-LRM (compatible with 10GBase-LRM) optics supports link lengths of 220m on standard Fiber Distributed Data Interface (FDDI) grade multimode fiber (MMF). When you use the OM1 or OM2 fibers connected with the 10GBase-LRM module, to make sure that specifications are met over FDDI-grade, the transmitter should be coupled through a mode conditioning patch cord. But it is fine when you use over the OM3 and OM4 fibers.

Conclusion

10G SFP+ transceiver is widely used to support communication standards including synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), 10 Gigabit Ethernet and fibre channel. Both 10GBASE-LR and 10GBASE-LRM SFP+ wins its own place on the market. They cannot substitute for each other!

Speeds in data centers have maintained their growth in the past years, and will continue to do so in the predictable future. High-data-rate systems have become increasingly popular among some enterprises for high-performance computing networks, such as 40 Gigabit Ethernet (GbE) infrastructure, in which 40G fiber optic transceivers and cables are needed to ensure the high-performance and great-bandwidth of the 40GbE system. This article mainly introduces 40G fiber optic transceivers: the pluggable optical Enhanced Quad Small Form-Factor Pluggable (QSFP+), with focus on the bidirectional optical transceivers and parallel optical transceivers.

40G Optical Transceiver Types

The transceiver is an electronic device that receives an electrical signal, converts it into a light signal, and launches the signal into a fiber. It also receives the light signal, from another transceiver, and converts it into an electrical signal. With the 40G QSFP being the dominant transceiver form factor used for 40GbE applications, the IEEE standard 802.3ba released several 40-Gbps based solutions in 2010, including a 40GBASE-SR4 parallel optics solution for multi-mode fiber (MMF). Another solution is a bidirectional 40-Gbps transceiver that uses a two-fiber LC optical interface.

40G Parallel Optical Transceiver

40G parallel optical transceiver enables high-bandwidth 40G optical links over 12-fiber parallel fiber terminated with MPO/MTP connectors. Four fibers on one side are used to transmit, while another four on the other side are utilized to receive, leaving the middle four fibers unused. In total, eight of the twelve fiber are used. That is to say, when used for 40GBASE-SR4 and 40GBASE-CSR4, parallel optical transceiver has 10-Gbps electrical lanes that are mirrored in the optical outputs, causing the requirement of eight fibers with a MTP connector interface. Each fiber either transmits (Tx) or receives (Rx) 10-Gbps traffic at a single wavelength.

Just as mentioned above, 40GBASE-SR4 QSFP+ transceiver belongs to 40G parallel optical transceivers, which uses multi-mode MPO trunks to establish 40G links. This port type 40G QSFP+ module can support link lengths of 100 meters and 150 meters over laser-optimized OM3 and OM4 MMFs respectively. It can also be used to connect with four 10GBASE-SR optical interfaces using an 8-fiber MTP to 4 duplex LC cable. fiber-mart.com listed 40GBASE-SR4 optical transceivers are fully compatible with such famous brands, as Cisco, Intel, Juniper (QFX-QSFP-40G-SR4), and so on. All are quality-and compatiblity-assured, offering the high performance to customers.

40G Bidirectional Optical Transceiver

By contrast, 40G bidirectional optical transceiver consists of two 20-Gbps transmit and receive channels, enabling an aggregated 40-Gbps link over a two-strand MMF connection. That is, the bidirectional optical transceiver used for 40GBASE-SR-BD uses the same 10-Gbps electrical lanes, which are then combined in the optical outputs, thus requiring two fibers with an LC connector interface. Each fiber simultaneously transmits and receives 20-Gbps traffic at two different wavelengths.

Just as mentioned above, 40GBASE-SR4 QSFP+ transceiver belongs to 40G parallel optical transceivers, which uses multi-mode MPO trunks to establish 40G links. This port type 40G QSFP+ module can support link lengths of 100 meters and 150 meters over laser-optimized OM3 and OM4 MMFs respectively.

Each fiber simultaneously transmits and receives 20-Gbps traffic at two different wavelengths.

Cabling Options for 40G Parallel & Bidirectional Optical Transceiver

Cabling Options for 40G Parallel Optical Transceiver

As previously mentioned, in 2010 IEEE 802.3ba approved the 40GBASE-SR4 physical-medium-dependent (PMD) multi-mode parallel optic solution, which uses eight fibers to transmit four duplex channels each at 10-Gbps. This is an economical path to 40GbE data rates, while using many of components of 10GbE solutions. The main advantage of the parallel optical transceiver over the bidirectional transceiver at 40GbE is the reach. For example, if you cable your data center with OM3 at 10GbE, you can support distances up to 300m. Then if you move to 40GbE, you can support the same 300m distance with the same OM3 fiber and a 40GBASE-CSR4 transceiver. However, if your cabling distances do not justify the extra distance capability, then the bidirectional solution would be used.

There exists a problem in this parallel optical cabling solution—MTP cable assemblies which built on 12-fiber position connectors, leaving four unused fibers in each link. There are several basic cabling options for parallel optics connectivity. One approach is to ignore the unused fibers and continue to deploy 12 fibers. Another approach is to use a conversion device to convert two 12-fiber links into three 8-fiber links.

Cabling Options for 40G Bidirectional Optical Transceiver

This two-fiber 40G bidirectional multi-mode solution tackles the challenge—polarity correction that occurs in a 12-fiber MTP connector., using two different transmission windows (850 and 900nm) that are transmitted bidirectionally over the same fiber. This approach allows the use of the same cabling infrastructure for 40GbE as was used for 1 and 10 Gigabit Ethernet. The pluggable bidirectional transceiver has the same QSFP+ format as the existing 40GBASE-SR4 transceivers. Therefore, the same switch line card with QSFP+ ports can support either parallel optics 40GBASE-SR4 or bidirectional optics 40GBASE-SR-BD solutions.

As such, while connecting a 40GbE bidirectional transceiver to another bidirectional transceiver, a Type A-to-B standard LC duplex patch cord can be considered, with one fiber in connector position A on one end and in connector position B on the other end. Such reverse fiber positioning allows a signal to be directed from the transmit position on one end of the network to the receive position on the other end of the network. However, this direct connectivity is recommended only within a given row of cabinets.

Conclusion

40G QSFP+ transceivers can meet the growing data center applications, such as big data and high-frequency trading (HFT) applications, and virtualized and clustered environments. With 40G bidirectional optical transceivers, no big changes to the existing cabling infrastructure are required, a cost-effective way for migration from 10-Gbps to 40-Gbps connectivity in data center networks. As a professional fiber optical product manufacturer and supplier, fiber-mart.com offers various 40G QSFP+ transceivers for your choice. Besides, many 40G cables (ie. QSFP-4SFP10G-CU5M) are also available for the smooth migration. For more information about 40GbE solutions (40G QSFP+ and 40G cables), you can visit fiber-mart.com.

The demand for better network throughput and performance has never ceased. Instead, it has become more and more vigorous. The server consolidation, virtualization, as well as networking-service performance improvements, all these have pushed the necessity for dense 40GbE switch connections in data centers.

But when migrating to 40GbE from10GbE, some companies or organizations are challenged by two main factors in re-configuring the physical layer of the network: firstly, the possible reduced reach of the OM3/OM4 multi-mode optics from 10GBASE-SR (300/400 m) to 40GBASE-SR4 (100/150m), and secondly, the need to upgrade the existing fiber optic cabling plant so as to support the IEEE-defined 40GBASE-SR4 parallel optics. In order to avoid these questions, SMF&MMF 40G QSFP+ transceiver is brought to the market.

SMF&MMF 40G QSFP+ Transceiver Definition

It’s know that a fiber optic transceiver may either operate on single-mode fiber (SMF) or multi-mode fiber (MMF). However, this SMF&MMF 40G QSFP+ transceiver is able to communicate with both SMF and MMF, without the need for any software/hardware changes to the transceiver module or any additional hardware in the network. It has 4 channels (1270, 1290,1310, and 1330nm) of 10G multiplexed inside the module to transmit and receive an aggregate 40G signal over 2 strands of fiber with a duplex LC connector.

Based on IEEE defined 40GBASE-LR4 specifications, this supports distances up to 150m over OM3 or OM4 MMF and up to 500m over SMF. Certainly, different fiber optic equipment vendors may have different specifications.

SMF&MMF 40G QSFP+ Transceiver Advantages

SMF&MMF 40G QSFP+ transceiver is designed for seamless migrations from existing 10GbE to 40GbE networking without modification or expansion of the fiber network. It addresses several challenges faced by today’s data centers and the passages highlight the advantages of this transceiver.

No Redesign or Expansion of Fiber Network

Other short-reach 40G QSFP+ transceiver types, such as MMF 40GBASE-SR4 transceivers (100m over OM3 MMF), utilize four independent 10G transmitters and receivers for an aggregate 40G link. These 40GBASE-SR4 transceivers (eg. JG325B) use a MPO-12 connector and require 8-fiber parallel OM3 or OM4. As a result, customers installing MTP/MPO fiber systems may need to deploy new fiber while upgrading from 10G to 40G. However, SMF&MMF 40G QSFP+ transceiver uses duplex LC connector, which is consistent with the existing 10G connections. It works on existing OM3 and OM4 MMF infrastructure which is widely installed and used for 10GbE networks, thus free from redesign or expansion of the fiber network.

Increase in the Number of 40G Links

The existing MMF 40GbE solutions use of 8 fibers for a 40G link, and customers have to add additional fiber if they want to increase the number of 40G links. But if you deploy SMF&MMF 40G QSFP+ transceiver, the number of 40G links is 4our times of that existing MMF 40GbE solutions without any changes to their fiber infrastructure. During this link increase, the network scale and performance are also expanded.

A Cost-effective Solution for SMF Infrastructure

Limited in the distance reach that multi-mode transceivers can support, the migration from 10G to 40G, to 100G, or even 400G would become simpler with SMF. But single-mode transceivers typically cost up to 4 times more compared to multi-mode transceivers. Since SMF&MMF QSFP+ transceiver interoperates with QSFP-LR4 and QSFP-LR4L optics, it’s a cost effective solution for SM fiber infrastructure for distances up to 500m. And customers can deploy mixed connections without fiber concerns.

Simplification in Infrastructure Deployment

SMF&MMF QSFP+ transceiver boasts of the unique characteristic of working through both SMF and MMF without any requirement for additional fiber. Customers can consolidate their optics and use SMF&MMF QSFP+ transceiver in their network without concern about the fiber type, which makes the full use of existing cabling infrastructure, leading to the reduced equipment cost and simplification of deployment.

Conclusion

SMF&MMF QSFP+ transceiver allows data centers to migrate from 10GbE to 40GbE without redesigning or modifying the cabling infrastructure, providing companies or organizations a cost-effective solution to expand their fiber network. With SMF&MMF QSFP+ transceiver in hand, a smooth 40GbE migration at low cost is around the corner. fiber-mart.com SMF&MMF 40G QSFP+ transceivers are supplied to help you achieve smooth 40G migration. Besides, their interoperate QSFP-LR4 and QSFP-LR4L transceivers are also available, such as Cisco QSFP-40G-LR4 and WSP-Q40GLR4L.

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.

Fusion splicing

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 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.

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.
