OM4 is an upgraded version of OM3 multimode jumper fiber. The fiber transmission distance can reach 550m. OM4 is developed for VSCEL laser transmission, and its effective bandwidth is more than twice that of OM3.
In 10Gb/s system transmission, the transmission distance can reach 300m to 600m; in 40Gb/s and 100Gb/s systems, the transmission distance ranges from 100m to 125m.
Supports 4Gb/s optical fiber link length of 400m, 8Gb/s optical fiber link length of 200m, or 16Gb/s optical fiber link length of 130m.
Optical Performance Indicator Requirements for Fiber Optic Connectors

b) The insertion loss of two plugs connected via a standard adapter shall be ≤ 0.3dB.
c) After various tests, the allowable variation of insertion loss shall be ≤ 0.2dB, and the variation of return loss shall be ＜ 5dB.
