OTDR signal injection for multi-band optical power balancing

A system, comprising:

• a first Optical Time Domain Reflectometer (OTDR) configured to inject a first OTDR signal at a first optical wavelength, a first power level and a first polarization state into an optical fiber,
• an OTDR monitor configured to:
• monitor multi-band optical signals, including a reflected OTDR signal corresponding to the first OTDR signal, on the optical fiber, and
• select a second power level and a second polarization state based on the monitoring of the multi-band optical signals,
• determine parameters associated with the optical fiber based on the monitoring, and
• wherein the first OTDR is further configured to inject a second OTDR signal at the first optical wavelength, the selected second power level and the selected second polarization state into the optical fiber to balance power levels associated with the multi-band optical signals.

A non-transitory computer-readable medium containing instructions executable by at least one processor, the computer-readable medium comprising:

• one or more instructions for causing a first Optical Time Domain Reflectometer (OTDR) to inject one or more first OTDR signals into an optical fiber, wherein the one or more first OTDR signals have a first optical wavelength, a first power level, and a first polarization state;
• one or more instructions for monitoring multi-band optical signals, including reflected OTDR signals corresponding to the first OTDR signals, on the optical fiber;
• and
• one or more instructions for causing the first OTDR to inject one or more second OTDR signals into the optical fiber, based on the monitoring of the multi-band optical signals, to balance power levels associated with the multi-band optical signals, wherein the one or more second OTDR signals have a second optical wavelength, a second power level and a second polarization state.
