We propose a passive optical network architecture based on coherent detection for converged delivery of broadcast services from a dedicated remote broadcast server and user-specific services from a local central office. We experimentally demonstrate this architecture with mixed traffic types, wavelength division multiplexed, unicast channels composed of four radio-over-fiber channels operating at 5 GHz carrier frequency with 250 Mbaud phase shift keying modulation and four 10 Gb/s baseband amplitude shift keying channels; while the broadcast channels were four 10 Gbaud DQPSK channels. The broadcast channels were transmitted over 78 km of single mode fiber to a central office where they were multiplexed with the unicast channels for further fiber transmission over 34-km to reach the access network. Successful detection of all channels is demonstrated.
