Wideband multimode fiber (WBMMF), officially designated as OM5, is a recently released fiber medium that is now recognized within both the Telecommunications Industry Association (TIA) and International Electrotechnical Commission (IEC) standards. OM5 fiber specifies a wider range of wavelengths between 840 and 953nm to support wave division multiplexing (WDM) technology and is fully backwards compatible with existing OM4 fiber specifications.
