Abstract:
1. A communication device having an embedded optical time domain reflectometer (OTDR), comprising: a first optical subassembly (OSA) embedded in a small form factor pluggable (SFP) package, the first OSA coupled to an optical fiber and having a first optical transmitter and a second optical transmitter, wherein the first optical transmitter is configured to transmit a first optical data signal at a first wavelength through the optical fiber, and wherein the second optical transmitter is configured to transmit an optical OTDR signal at a second wavelength through the optical fiber; a second OSA embedded in the SFP package, the second OSA coupled to the optical fiber and having a first optical detector and a second optical detector, wherein the first optical detector is configured to detect a second optical data signal at a third wavelength from the optical fiber, and wherein the second optical detector is configured to detect returns of the optical OTDR signal from the optical fiber; and logic configured to define data indicative of at least one anomaly along the optical fiber based on the returns of the optical OTDR signal.
