What is a multimode fiber optic cable?

Multimode fiber (Multi Mode Fiber) - core coarse (50 or 62.5μm), to be available for a variety of modes of light. But its mode dispersion larger, which limits the frequency to transmit digital signals, and with the increase in distance will be more severe. Therefore, the multi-mode fiber transmission distance is relatively close, usually only a few kilometers. The following table, for the multimode fiber bandwidth comparison:

Gigabit multimode fiber optic cable that needs to be some clarification, fiber optical signal transmission system, optical transceivers and fiber can not be separated. Because of the traditional multi-mode fiber can only support Gigabit transfer tens of meters, in line with the new Gigabit applications while the use of optical transceivers, ISO / IEC 11801 to develop a new standard grade multimode fiber, which OM3 category, and in 2002 promulgated in September. OM3 fiber bandwidth, two kinds of LED and laser models are optimized, while subject to strict testing and certification of DMD. The new standard fiber optic cabling system can support multi-mode Gigabit transmission mode, at least to 300 meters, while in single mode, can reach 10 km (1550nm can also support 40-km transmission).

U.S. CommScope's multi-mode multi-mode fiber optic cable into OptiSPEED ® solution (62.5/125μm) and Gigabit multimode LazrSPEED ® solution (laser optimized Gigabit 50/125μm). LazrSPEED divided into three series, namely LazrSPEED 150,300,550 series, and LazrSPEED Gigabit multimode fiber optic cable are certified by UL DMD.
