MIMO-less space division multiplexing transmission over 1 km elliptical core few mode fiber

摘要

We experimentally demonstrate 10-Gbit/s OOK MIMO-less SDM transmission over 1 km of a three-spatial-mode elliptical-core fiber at 1550 nm. Negligible power penalty is achieved thanks to the low modal crosstalk (<-22 dB) between any pair of the LP01, LP11a and LP11b modes.
