CA 2459611

A system and method for transmitting an optical signal through a downstream link of a Wavelength Division Multiplex (WDM) optical communications network, comprising a detector/filter for monitoring wavelength channels at an upstream link. An input source/filter transmits the optical signal in the wavelength channels through the downstream link. A controller receives data to be transmitted as an optical signal. The controller is connected to the detector/filter for detecting unused wavelength channels as a function of the monitoring from the detector/filter, for selecting one of the unused wavelength channels, and being connected to the input source/filter for controlling the transmission of an optical signal associated with the data on the selected wavelength channel.
