Claim Text:
1. A telecommunications monitoring method, comprising: receiving an incoming optical signal at a downstream termination point, located within an optical multiplexor box, of an optical fiber; splitting, within the optical multiplexor box, the incoming optical signal into a data optical signal and a test optical signal; tapping the data optical signal to produce a tapped optical signal; processing, within the optical multiplexor box, the data optical signal to produce a data electrical signal indicative of data encoded in the incoming optical signal; processing the tapped optical signal to produce an electrical signal indicative of a power of the data optical signal; and performing, by an optical time-domain reflectometer (OTDR) module within the optical multiplexor box, OTDR monitoring of an optical fiber selected from: an incoming optical fiber associated with the incoming optical signal and an outgoing optical fiber associated with an outgoing optical signal.
