Q: What is Wideband Multimode Fiber?
A: Wideband multimode fiber (WBMMF) is an emerging fiber optic cable design that will permit transmission of 4x the current amount of data transmitted on a single multimode fiber optic strand. The optical strands are designed to allow the simultaneous transmission of 4 different wavelengths of light, quadrupling the throughput. For example, a pair of OM4 multimode fibers that can currently accommodate 10 gigabit Ethernet (10G-BaseSR) will be able to accommodate 40 gigabit Ethernet. This will be done using another technology coming to market, Short Wave Division Multiplexing.
