|||||||||
The MaxBand-OM4 multimode fiber complies with or exceeds IEC 60793-2-10 type A1a.3 Optical Fiber Specification, ISO/IEC 11801 OM-4 Specification, TIA/EIA-492AAAD detail Specification.
OM4 fiber offers a minimum effective modal bandwidth of 4700 MHz-km at 850 nm, compared with 2000 MHz-km for OM3. This OM4 fiber is a 50 μm laser-optimized fiber with extended bandwidth with 40 and 100 Gigabit Ethernet speeds, supports Ethernet, Fiber Channel, and OIF applications, allowing extended reach upwards of 550 meters at 10 Gb/s for ultra long building backbones and medium length campus backbones. With an Effective Modal Bandwidth of 4700 MHz-km(more than double the IEEE requirement for 10 Gb/s 300 meters support ),OM4 fiber is also especially well suited for shorter reach data Centers and high performance computing applications.
