120-Gb/s 100-m transmission in a single multicore multimode fiber containing six cores interfaced with a matching VCSEL array

Over 100 Gb/s is carried across a single 100-m strand of multicore multimode fiber. A custom VCSEL array transmits 16.7 to 20 Gb/s/channel into six cores housed within a 125-μm cladding. Negligible crosstalk is observed. © 2010 IEEE.
