OM2 Duplex multimode fiber is recognized

Laser optimized multimode fiber is recognized as the medium of choice to support these high speed data networks. With next-generation 40 and 100 Gigabit Ethernet speeds on the horizon, the industry is developing a new type of multimode fiber, called OM4, there is now a standard that is specifically targeted at this product. Prior to the standardization of OM4, these higher bandwidth fibers were sold as a part of OM3.Which will offer a minimum effective modal bandwidth of 4700 MHz-km at 850 nm, compared with 2000 MHz-km for OM3 fiber optic cableFor many years 62.5/125 μm (OM1) and conventional 50/125 μm multi-mode fiber OM2 Duplex were widely deployed in premises applications. These fibers easily support applications ranging from Ethernet (10 Mbit/s) to Gigabit Ethernet (1 Gbit/s) and, because of their relatively large core size, were ideal for use with LED transmitters. Newer deployments often use laser-optimized 50/125 μm multi-mode fiber (OM2 Duplex). Fibers that meet this designation provide sufficient bandwidth to support 10 Gigabit Ethernet up to 300 meters. Optical fiber manufacturers have greatly refined their manufacturing process since that standard was issued and cables can be made that support 10 GbE up to 550 meters. Laser optimized multi-mode fiber (LOMMF) is designed for use with 850 nm VCSELs. Today, this evolution continues with the development of OM4 multimode fiber as the industry prepares itself for speeds of 40 and 100 Gb/s.
