Multipath optical transmission system controller.

摘要

Utilization of an electrical link separate from an optical transmission path to gather information identifying the number and types of optical devices in the optical path and utilization of this information to adjust the power output level of an optical transmitter and to transmit the power output level to optical receivers connected to the optical transmitter by the optical path. Each optical receiver (145, 150) is responsive to the number and types of optical components in the path between the optical receiver and the optical transmitter (128) and the power output level to adjust the sensitivity of the optical receiver. Each optical component is associated with an electrical identification circuit (111, 112, 114, 115) connected to the electrical link which specifies the information on the electrical link concerning the optical component including the performance characteristics of the optical component.
