10G Ethernet Transmission MPO System Scheme

June 2002, IEEE802.3ae Task Force issued a series of fiber-based Gigabit Ethernet standard, commonly used in LAN 10GBase-SR/SW as example, 10GBase-SR/SW using serial transmission technology, that is, each core optical fiber only send or receive signals, so to achieve 10Gbps transmission requires at least two-core optical fiber.

MPO fiber optic deployment system has two solutions, one is to use the program with MPO module box, because MPO module box is with metal needles, therefore MPO trunk cables do not need to distinguish whether with a metal pin (Pin), most users tend to use MPO module case scenario; another option is to use MPO coupler, such programs must differentiate between MPO trunk cables with metal needles and without metal pin, the other two ends need to convert Fiber Jumper, so this program is rarely adoption.

According ANSI/TIA-568-C.3 standards are divided into the following two types of duplex Fiber jumpers:

Standard: (A-B) Non-Standard: (A-A) According ANSI/TIA-568-C.3 standard, MPO coupler is divided into Type A, Type B two types:   MPO fiber optic system according to the MPO trunk cables, MPO module boxes and jumpers of different types have different combinations of programs, mainly A, B, C three kinds of channel combination scheme

Method A: Using straight-through (Type A) of MPO trunk cables, Fiber Jumpers must be used at both ends of different models, Scenario A increases the complexity of the orders, it is not recommended to use programs A.

Method B: A fully cross (Type B) of MPO trunk cables, MPO module box must use two different types (Key Up-Key Up) and (Key Down-Key Down), another plan B does not support the ramp octave end face (singlemode fiber, so most manufacturers do not recommend using program B.

Method C: Using lines cross (Type C) of MPO trunk cables, MPO consistent at both ends of the module box (Type A) and standard jumpers, so Option C is the solution of choice for 10G Ethernet recommended.

There are some related MPO products from fiberstore, you can see to know more about MPO Fiber.

12 Fibers, Single-Mode, 12 Standard MPO Fiber Cable,3.0mm LSZH

FiberStore offer singlemode and multimode (OM1, OM2, 10G OM3, 10G OM4) MPO/MTP Cable. Singlemode MPO MTP Fiber cable is primarily used for applications involving extensive distances, 10G Mpo Cassettes provide 10 gigabit 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. The meanwhile, we also provide 40G/100G MPO/MTP trunk cable.

The Development and Application of MPO/MPT Multi Core Fiber Connector

MPO / MTP high density fiber optic connection system currently used mainly for three pre areas: Application of high-density data center environments,application of fiber to the building, application of internal connections in the splitter, 40G, 100G SFP, SFP + optical transceiver equipment, etc. This article highlights why the data center use MPO / MTP high density fiber optic cables connection system and how choose these high-density fiber optic connection system.

In communications, data transmission field, the development of fiber optic connectors is more prolific than copper connectors. According to incomplete statistics, so far, fiber optic connectors developed hundreds of different kinds, but only a dozen can widely use. Fiber optic connector has two distinct stages of development. The first stage, to save space, develop to miniaturization, the fiber optic connector is from traditional FC, ST, SC connectors to LC,MTRJ.

The second stage, it is not only to save space, but also to meet the requirements for use of multi-core, fiber optic connectors evolved from LC, MTRJ, E2000 to MU, MTP/MPO, now an MTP / MPO connectors can meet the 2 core, 4 core, 8 cores, 12 cores, 24 cores, up to 72 core requirements.
 

It is the last few years that MPO MTP Fiber pre-connected system use in the data center. Why not the MPO / MTP pre-connected systems widely used?

First, data center space is never enough. To solve the shortage sapce can increase the space or improve the utilization of space. It is unrealistic in a designed data center, Improvement of space utilization is to increase density. As the two major data center cabling system: copper, fiber optic cable. Copper system can use high density, but this high density is limited to space-saving. It is not only satisfy the high frequency, but also to find a balance between the larger line through. So in the same space to get more bandwidth, using optical transmission is an inevitable choice, but this does not mean necessarily require high-density fiber optic connection system.

Secondly, the result of network speed and improvement, in terms of fiber optic, core fiber can support the application of 100MB, 1000MB, and 10000MB. More than 200 experts fiberstore working group launched application to support this standard. The following chart we can see a single channel or 4-core 10-core optical fiber, normal 40G and 100G fiber optic network communications are 8-core and 20-core optical fiber. This challenges to traditional dual-core optical fiber transmission, it requires to use a high-density multi core optical fiber. [caption id="attachment_2061" align="alignnone" width="300"]

How do guarantee the performance pre-connected high-density MTP/MPO fiber optic system products in the factory? What is differet from common fiber optic cables?

First the commany must meet the ISO9000 series of quality management system certification, and production process and product performance also meet certification standards of the most comprehensive and the most stringent of fiber optic connector assembly production. Now many factory can produce fiber optic cables.

For another, understand the MPO MTP Fiber system products, whether polarity module or truck fiber cable, whether fiber optic harness or MPO Fiber cable is more complex than SC and LC fiber.

At last, this article discusses the reason of using MPO / MTP high density fiber optic connection system, and give some adive to this new system, fiberstore hope it is helpful to the user of data center and the same occupation.
