3-mode Real-time MDM Transmission Using Single-mode OTN Transceivers over 300 km Weakly-coupled FMF

Abstract

Utilizing non-degenerate LP 01 /LP 02 /LP 03 modes in a weakly-coupled 10-LP-mode multiple-ring-core FMF and corresponding mode multiplexers/demultiplexers consisting of cascaded mode-selective fiber couplers, we experimentally demonstrate a real-time 300-km MDM transmission with commercial single-mode 200G OTN transceivers.
