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) 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 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 function on the same wavelength with the optical transceiver responsive to a disruption in the data communications;
- gathering measurements from the OTDR 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.
