An optical transceiver includes a single integrated circuit chip to integrate the drive, receive, control, and monitoring functions of the optical transceiver. The single chip may further have an advance replacement algorithm and monitoring algorithm for the opto-electronic devices of the optical transmitter and receiver to generate flags and/or an advance replacement indication. Methods, apparatus, and systems are disclosed.

Integrated driving, receiving, controlling, and monitoring for optical transceivers

Methods of determining the performance and the advanced failure of an optical communication channel. Performance of an optical communication channel may be determined by receiving light signals, generating a measure of an average received optical power in the received light signals and monitoring changes in the measure of the average received optical power. Advanced failure of an optical communication channel may be determined by transmitting a light signal at one end of the optical communication channel, propagating the light signal in an optical transmission medium, receiving the light signal at an opposite end of the optical communication channel, generating an electrical signal responsive to the receiving of the light signal. determining a measure of an average received optical power in the received light signal in response to the electrical signal, and monitoring changes in the measure of the average received optical power.

Methods for determining the performance, status, and advanced failure of optical communication channels

Methods, systems and apparatus for measuring average received optical power by an optical receiver. A TO-package for a packaged optical receiver is disclosed having a pin-out configuration for facilitating the direct measurement of the level of photo current induced into an optical receiver. A method and system are disclosed which include the packaged optical receiver for measuring the average received optical power by an optical receiver.
