YOFC MaxBand® OM4 Ultra Bending Insensitive Multimode Fibre is designed for 100G/lane and Terabit BiDi technology, offering high bandwidth in the wavelength range of 850nm - 870nm & 910nm. It can compensate the signal degradation caused by 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 Ultra 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.
