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 850 nm - 870 nm & 910nm. It can compensate the center wavelength shift of 100G/Lane transceivers, ensuring smooth upgrades to 400G, 800G, and higher data rates for data center. It is fully backward compatible with legacy OM4 and OM5 fibres. Compared to OM5, it is more cost-effective and can maintain significant cost and power advantages in high-speed links.
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.
