The explosion in demand for bandwidth in enterprise networks is driving an urgent need for higher Ethernet network speeds. Several factors are contributing to this, including broadband penetration fueled by video-rich content, Data Center demands, and exponential growth in supercomputer and R&D computing activities. Laser-optimized multimode fiber is recognized as the medium of choice to support these high-speed data networks. With next-generation 40 and 100 Gigabit Ethernet speeds on the horizon, the industry is developing a new type of multimode fiber, called OM4, which will offer a minimum effective modal bandwidth of 4700 MHz-km at 850 nm, compared with 2000 MHz-km for OM3.|The explosion in demand for bandwidth in enterprise networks is driving an urgent need for higher Ethernet network speeds.
