1. An optical distribution terminal, comprising:

  • a laser diode operable to receive an electrical signal, the electrical signal corresponding to a video source signal, the laser diode operable to generate a video optical signal at a first wavelength in response to the electrical signal;

    a multiplexer operable to receive the video optical signal at the first wavelength, the multiplexer operable to receive a telephony optical signal at a second wavelength over a first optical fiber, the multiplexer operable to transmit the video and telephony optical signals in their respective first and second wavelengths over a second optical fiber, the multiplexer operable to receive a return video optical signal and a return telephony optical signal at the second wavelength over the second optical fiber, the multiplexer operable to transmit the return video and telephony optical signals at the second wavelength over the first optical fiber. distribution circuitry for transmitting the received video and telephony signals to a plurality of subscribers and for receiving the telephony return signals and the video return signals from the plurality of subscribers; and

    a multiplexer for combining the telephony return signals and the video return signals to generate the multiplexed return signals.
