Multimode fiber (MMF) cabling is the workhorse media of local area network (LAN) backbones and data centers because it offers the lowest cost means of transporting high data rates for distances aligned with the needs of these environments. MMF has evolved from being optimized for multi-megabit per second transmission using light emitting diode (LED) light sources to being specialized to support multi-gigabit transmission using 850 nm vertical cavity surface emitting laser (VCSEL) sources. Channel capacity has been multiplied through the use of parallel transmission over multiple strands of fiber. These advances have increased multimode supported data rates by an astounding factor of 40,000 from 10 Mb/s in the late 1980s to 100 Gb/s in 2010, with 400 Gb/s in development in 2015. Today, these extraordinary rates are created from collections of 25 Gb/s lanes carried on either four or sixteen strands of fiber in each direction.  Clcik here to read more.
