Abstract
An optical signal transmission apparatus and a method are provided. The apparatus may include a set of optical transmitters, each optical transmitter configured for transmission of light signals at one or more wavelengths of light. The apparatus may include an output port configured for transmission of the light signals through a span of optical fiber. The apparatus may use an input port configured to receive other transmissions of light signals through the span of optical fiber. The apparatus may include a set of light detectors, each light detector configured to detect a time delay or phase characteristic associated with the one or more wavelengths of light. The apparatus may include a processor configured to determine a metric based on the detected time delay or phase characteristic.
