#OM TYPES
Below, observe that the bandwidth and performance figures for OM4 and OM5 are identical. The primary distinction between OM4 and OM5 is that OM5 has intended for usage at wavelengths more than 850 nm, notably 880, 910, and 940 nm. This indicates that it supports wave division multiplexing (WDM) technology and four simultaneous broadcasts.
The typical fiber-based Ethernet applications, supported distances for each OM, and related loss limits are shown in the table below. For an application to function, distance and loss must be considered.
