We propose and experimentally demonstrate a bidirectional Community Antenna Television/radio‐over‐fibre (RoF) hybrid transmission system based on incoherent light injection and RF amplifier pre‐distortion to reduce third‐order non‐linearity. At downlink, 10‐Gbps/30‐GHz data and 79 CATV channels are transmitted over 50 km single‐mode fibre (SMF), and at uplink 5‐Gbps/15‐GHz data and CATV signals are successfully transmitted concurrently over 50 km through the same SMF. The authors have found low bit‐error rate (BER) and clear eye diagrams for the RoF data signals, and obtained outstanding transmission performance in terms of carrier‐to‐noise ratio, composite second order, and composite triple‐beat for the CATV signals in downlink and uplink transmission.
