Abstract: A method of selecting a group of multimode optical fibers, includes comparing a first effective modal bandwidth at a first wavelength of a multimode optical fiber with a first effective modal bandwidth threshold at the first wavelength, the multimode optical fiber being in a group of multimode optical fibers meeting a first OM standard, wherein the first wavelength is from 844 nm to 863 nm; and categorizing the multimode optical fiber as passing a transmission distance requirement if the first effective modal bandwidth of the first multimode optical fiber is greater than or equal to the first effective modal bandwidth threshold; wherein the transmission distance is defined in a transceiver specification, wherein the transceiver specification is one or more of: (a) an 800G bidirectional (BiDi) transceiver specification, or (b) a 100G/lane based MM VCSEL transceiver specification, or (c) a 25Gbaud based transceiver specification, or (d) 50G PAM4 based transceiver specification.
