YOFC MaxBand® OM4 Pro Bending Insensitive Multimode Fibre can support transmission distances of
100m and 70m in 100G/lane and Terabit BiDi links which complies with or exceeds IEEE 802.3db
specification and Terabit BiDi MSA specification.
MaxBand® OM4 Pro Bending Insensitive Multimode Fibre
YOFC MaxBand® OM4 Pro Bending Insensitive Multimode Fibre is designed for 100G/lane technology, offering high bandwidth in the wavelength range of 850nm - 870nm. It can compensate the center wavelength shift of 100G/lane transceivers, ensuring smooth upgrades to 400G, 800G, and higher data rates for data centers. It is fully backward compatible with legacy OM4 and OM5 fibres.
YOFC MaxBand® OM4 Pro Bending Insensitive Multimode Fibre complies with or exceeds ISO/IEC 11801-1 OM4 specification, IEC 60793-2-10 A1-OM4 specification, and TIA-492AAAF A1-OM4 specification.
