Abstract: 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 +1 and OAM -1 modes carrying 10Gbase-T signals in the downlink and uplink transmission experiments, achieving less than -15.11 dB crosstalk.
