We present a novel method for providing broadcast signal transmission in a wavelength division multiplexing passive optical network (WDM-PON). An unmodulated optical carrier for downstream transmission and a pair of unmodulated single-side band subcarriers are utilized for broadcast delivery and upstream transmission, respectively. System performance at 2.5-Gb/s down/upstream and 2.5-Gb/s broadcast transmission is also investigated.
