A wavelength division multiplex optical system includes a WDM combiner to provide a source signal, at least one transmitter coupled to an input of the WDM combiner, a broadband noise source, and a filter coupled between the broadband noise source and another input of the WDM combiner. In one embodiment, the filter is an optical notch filter. In an alternative embodiment, the filter includes a WDM demultiplexer coupled through plural filters to provide a plurality of noise signals and a WDM multiplexer coupled through at least one filter of the plural filters to respective noise signals.

Optical fiber transmission system with noise loaded idler channels

A method and apparatus for maintaining an established error count for data transmitted on a wavelength division multiplexed (WDM) optical communication network. Error counts from a forward error correction (FEC) code are monitored and operational parameters are automatically adjusted in response to the error counts, thereby achieving system optimization in an automated manner.
