    摘要： An optical triplexer transceiver that utilizes parallel signal detection for use in broadband passive optical networks (B-PONs). The triplexer transceiver includes an optical filter comprising a first port coupled to a laser for receiving upstream optical data signals, a second port for passing the upstream optical data signals to a network, and for receiving combined downstream optical data and video signals from the network, the video signals modulated by subcarrier modulation (SCM), and a third port for communicating the combined downstream optical data and video signals to a photodetector constructed and arranged for simultaneously receiving the combined downstream optical data and video signals and converting the optical data and video signals to electrical signals. A plurality of filters are coupled to the photodetector for separating the combined downstream data and video signals, including a low-pass filter for passing the downstream data signals, and a band-pass filter for passing the video signals. The video signals are coherently detected in a number of stages corresponding to stages of SCM applied to the video signals. The triplexer transceiver is adapted to receive optical video signals that have been subjected first and second stages of SCM to move the spectra of the SCM video signals to a higher frequency range that does not overlap with a frequency range of the baseband data signals.
