Fiber-optic testing source and fiber-optic testing receiver for multi-fiber cable testing

A method comprising:

• implementing, via one or more selective optical fibers of a plurality of optical fibers of a multi-fiber cable that is to be analyzed by at least one of a power meter or a source, a communication channel by the power meter and the source to transmit data from the power meter to the source or from the source to the power meter, wherein the communication channel is operable independently from a polarity associated with the multi-fiber cable;
• transmitting, from the power meter to the source or from the source to the power meter, an initial signal, wherein the power meter or the source that transmits the initial signal is designated as a transmitting sensor, and the power meter or the source that receives the initial signal is designated as a receiving sensor;
• transmitting, from the receiving sensor to the transmitting sensor, a mirrored signal that is generated based on an analysis of the initial signal;
• and
• determining, based on a comparison of a time delay between the initial signal and the mirrored signal to a reference time delay, a length of the multi-fiber cable.

A Multi-fiber Push On (MPO) tester for testing a multi-fiber cable, the MPO tester comprising:

• at least one laser source communicatively coupled, based on a specified communication channel, to one or more selective optical fibers of a plurality of optical fibers connected to a connector;
• and
• at least one photodiode communicatively coupled, based on the specified communication channel, to the one or more selective optical fibers of the plurality of optical fibers or at least one other optical fiber of the plurality of optical fibers to implement the specified communication channel that is operable independently from a plurality of polarities associated with the multi-fiber cable,
• wherein a number of the one or more selective optical fibers is less than a total number of the plurality of optical fibers.
