US Patent 7599625 Method of initializing optical communication links

A method of initializing an optical communication link between nodes. Optical transmitters adapted to pre-compensate link impairments based upon an optical compensation parameters are utilized to establish an optical communications link. Pre-compensation parameter values are selected at a node for generating an optical signal. The value is selected until confirmation from the remote node is received that the optical signal transmission has been successful. The successful pre-compensation parameter value is then used to generate the optical signal for the communications link.
