Abstract
A system and method for performing an in-service optical time domain reflectometry test, an in-service insertion loss test, and an in-service optical frequency domain reflectometry test using a same wavelength as the network communications for point-to-point or point-to-multipoint optical fiber networks while maintaining continuity of network communications are disclosed.
Claims20
A method of monitoring an optical fiber with at least one optical transceiver having an optical time domain reflectometry (OTDR) and/or optical frequency domain reflectometry (OFDR) function that is disposed to couple to the optical fiber, the method comprising:
- connecting an optical transceiver to a network terminal, the optical transceiver having OTDR and/or OFDR function and the network terminal is configured to read information from the optical transceiver;
- coupling the optical fiber to the optical transceiver;
- performing data communications on a same wavelength with the optical transceiver;
- performing OTDR and/or OFDR function on the same wavelength with the optical transceiver responsive to a disruption in the data communications;
- gathering measurements from the OTDR and/or OFDR function to determine at least one fault on the optical fiber;
- storing the measurements in the optical transceiver;
- reading the stored measurements from the optical transceiver to the network terminal, and
- reporting by the network terminal of the at least one fault on the optical fiber.
