Abstract
A system and method of operation of an optical network communication system includes: an optical fiber; an optical link attached to the optical fiber; a data transmitter for sending a downstream data message at a downstream data wavelength in the optical link; an optical time domain reflectometry (OTDR) transmitter for sending a OTDR broadcast pattern continuously at an OTDR wavelength different from the downstream data wavelength in the optical link; a broadband photo detector coupled to the optical fiber; and an OTDR receiver for receiving an OTDR reflected response pattern on the broadband photo detector during an open time slot not used for receiving an upstream data message for indicating an optical fault and for calculating an error distance along the optical fiber based on the optical fault.
