Application and Development of Optical Fiber Technology

Data center cabling system needs to continuously upgrade the bandwidth for the fast-growing network (such as the network core layer, convergence layer network and SAN storage network) transmission applications ahead of paved roads, and the use of optical fiber transmission can provide protection to continue to explore the bandwidth potential. Compared with single-mode fiber, due to lower active + passive integrated technology costs, multimode fiber will has an absolute advantage in the application of the data center, medium and large data centers are more than 85% of the fiber optic cabling system with multi-mode fiber. August 2009, TIA formally approved OM4, a new category EIA/TIA492AAAD standard of multimode fiber launch, it offers good prospects for the future large-scale application of multimode fiber, multimode fiber from OM1 to OM2, optimizing the use of VCSEL laser After a full technical of OM3 and OM4 developed four stages, the bandwidth is also progressively increase, from all levels of bandwidth and other correspondence between 10G transmission as shown below. Nowdays there are many companys to offer patch cord in the market.

Following the June 2010 IEEE802.3ba new Ethernet 40G/100G standard release, multimode fiber applications in the data center will open a new page, 40G and 100G high-speed transmission is no longer just rely on the use of single-mode high cost of WDM serial transmission, the new generation of Ethernet 40G/100G OM3 and OM4 standards will adopt a multi-channel parallel multi-mode fiber transmission mode, the multi-mode and single-mode transmission mode compared to the serial transmission WDM way on 40G/100G total cost (including active devices, optical modules, passive components) are only single-mode system 1/3 and 1/10, visible multimode advantages are obvious applications market trends often by cost and price factors to drive mode with which technology can take big decisions largest application in the market. if you want buy the cheap but high quality OM3 and OM4 fiber, according to the fiber connetors, we have Lc Lc Fiber in our store.



40G multimode fiber transmission mode supports 10Gbps using each pair of rate 4 * 10Gbp = 40Gbps, it needs to use all four fibers send and receive 8-core optical fiber, 100G uses 10 fibers each sending and receiving 10 * 10Gbps = 100G , a total of 20 core optical fiber, using the standard MTP / MPO multi-pin connector system will be able to transfer to better support the next generation optical network 40G/100G, 40G and 100G in the multi-core optical fiber transmission mode as shown below (2) shows, 40G transmission mode within 12 core MTP / MPO connectors on each side which take four core outermost transmission, intermediate 4-core is vacant, and 100G transmission mode is the use of two 12-core MTP / MPO  which take the middle 10 connector pin for transmission, if using MTP / MPO high-density 24-pin connector, complete the reception and transmission of 100G on a 24 core MTP/MPO connectors. When 100G transmission, both sides of the core of every 12 cores are vacant. The Mpo Fiber from our store are cheaper than other suppliers, you can go to our site to have a look.



As the new generation of standards and application standards 40G/100G, optical fiber technology have been introduced for data center planners, they have a more definite fiber types to choose the direction, OM3 and OM4 fiber will become the mainstream data center, multimode OM3, OM4 fiber were used in 40G/100G corresponding distance transport protocol and application support, although 40G/100G transmission distance of multimode and single-mode fiber can not be up to 10KM or 40KM comparison, but in the data center indoor application environment, according to statistics of small and medium data centers more than 90% of the fiber link length is less than 100 meters, a large data center more than 70% of the fiber link length is less than 100 meters, more than 80% of the length is less than 125 meters, multimode meet the needs of the vast majority of the link, with the upgrading of network equipment and technology, in the future, multi-mode fiber transmission distance may increase further.
