Abstract
A method is provided for increasing downstream bandwidth in an optical network that includes providing a downstream terminal comprising a digital output path and an analog output path. The method also includes receiving a signal comprising at least one wavelength at the downstream terminal. The method further includes selectively processing the signal at the downstream terminal. The signal is selectively processed at the downstream terminal by processing the signal on the analog output path if the signal comprises analog video data and processing the signal on the digital output path if the signal comprises data to be converted to a digital bit stream.

A method for increasing downstream bandwidth in an optical network, comprising:
- providing a downstream terminal comprising a digital output path and an analog output path;
- receiving a signal comprising at least one wavelength at the downstream terminal;
- and
- selectively processing the signal at the downstream terminal, wherein selectively processing the signal at the downstream terminal comprises processing the signal on the analog output path if the signal comprises analog video data and processing the signal on the digital output path if the signal comprises data to be converted to a digital bit stream.
A downstream terminal for an optical network, comprising:
- a digital output path;
- an analog output path;
- and
- at least one receiver coupled to the digital output path and the analog output path, the at least one receiver operable to receive a signal comprising at least one wavelength at the downstream terminal;
- and
- wherein the downstream terminal is operable to selectively process the signal at the downstream terminal by processing the signal on the analog output path if the signal comprises analog video data and processing the signal on the digital output path if the signal comprises data to be converted to a digital bit stream.
A system for increasing downstream bandwidth in an optical network comprising a downstream terminal for an optical network, the downstream terminal comprising:
- a digital output means;
- an analog output path;
- and
- at least one receiver coupled to the digital output means and the analog output means, the at least one receiver operable to receive a signal comprising at least one wavelength at the downstream terminal;
- and
- means for selectively processing the signal at the downstream terminal, wherein selectively processing the signal at the downstream terminal comprises processing the signal on the analog output means if the signal comprises analog video data and processing the signal on the digital output means if the signal comprises data to be converted to a digital bit stream.
