Multimode transceiver for interfacing to multicore graded-index fiber capable of carrying 120-Gb/s over 100-m lengths

A 24-channel multimode optical transceiver is developed for interfacing four six-core strands of multicore multimode fiber. The multicore fiber transmitter demonstrates 120-Gb/s/fiber low-crosstalk aggregate transmission, while the receiver has a circuit-limited bandwidth of 15 Gb/s/channel.
