  • Publication number: 20140056582
    Abstract: In general, techniques are described to detect potential issues with optical fibers. The techniques may be implemented using various optical network hardware. An example optical network unit (ONU) includes a network interface coupled to an optical fiber through which the ONU communicates with an optical line terminal (OLT). The ONU further includes a control unit that determines at least a first signal strength and a second signal strength of a signal received via the optical fiber, determines a rate of signal strength degradation based on the first signal strength and the second signal strength, compares the rate of signal strength degradation to a rate threshold so as to determine a potential issue with the optical fiber, and based on the comparison, causes the network interface to send a message to the OLT indicating a potential issue with the optical fiber to which the ONU connects to communicate with the OLT.
