OM5 is especially optimized to support bidirectional (40G-SR-BD and 400G-SR4.2) and wavelength division multiplexing (SWDM) technologies over multimode fiber by opening a wider spectral range to 840nm to 953nm. OM5 cable links offer longer supported distances for these technologies and OM5 patch cables are backwards compatible with older OM4/OM3/etc. standards.
