Abstract:
1. An optical communication system, comprising: a first optical transmitter optically coupled to at least one optical fiber; a first transmit driver configured to drive the first optical transmitter with a correlation sequence such that the first optical transmitter transmits the correlation sequence through the at least one optical fiber; a second optical transmitter optically coupled to the at least one optical fiber and thermally coupled to the first optical transmitter; a second transmit driver configured to drive the second optical transmitter based on the correlation sequence such that temperature fluctuations in the first optical transmitter are reduced; a first detector optically coupled to the at least one optical fiber and configured to detect returns of light from the first optical transmitter, the first detector configured to transmit a first electrical return signal indicative of the returns of light from the first optical transmitter; and an optical time domain reflectometer (OTDR) module configured to determine values indicative of at least one anomaly along the at least one optical fiber based on the first electrical return signal.
