All-Fiber Full-Duplex Bidirectional Data Transmission for Data Center Networks (DCNs) over 2-km Orbital Angular Momentum (OAM) Fiber using Commercial SFP+ Transceivers and Mode Selective Couplers

摘要

We experimentally demonstrate an all-fiber full-duplex bidirectional data transmission link for data center networks (DCNs) using orbital angular momentum (OAM) multiplexing over 2-km OAM fiber. Commercial SFP+ transceivers and mode selective couplers are employed to excite OAM₊₁and OAM_-1modes carrying 10Gbase-T signals in the downlink and uplink transmission experiments, achieving less than -15.11 dB crosstalk.
