We report successful reception of dual-LP11-mode CO-OFDM signals traversing few-mode compatible Optical Add/Drop Multiplexer(OADM).The OADM utilizes thin film filters and a double-reflection mechanism to perform add/drop functions of mode-division multiplexed signals.The power penalties for add
drop and through ports are 2.6
2.4 and 0.7 dB respectively for 3×318 Gbit/s OFDM signals.
