Abstract: A pluggable bidirectional optical amplifier module may include preamp and booster optical amplifiers and a housing. The preamp optical amplifier may be configured to amplify optical signals traveling in a first direction. The booster optical amplifier may be configured to amplify optical signals traveling in a second direction. The housing may at least partially enclose the preamp optical amplifier and the booster optical amplifier. The pluggable bidirectional optical amplifier module may have a mechanical form factor that is compliant with a pluggable communication module form factor MSA. A colorless mux/demux cable assembly may be operated with the pluggable bidirectional optical amplifier. The colorless mux/demux cable assembly may include a 1:N optical splitter a N:1 optical combiner coupled side-by-side to the 1:N optical splitter, a first fiber optic cable optic cable, and a second fiber optic cable.

Abstract: An OTDR system utilizes a laser source that is turned “on” and kept powered until its light reaches the end of the fiber span being measured (i.e., until the fiber span is fully illuminated). At any point in time after the fiber is fully illuminated, the laser source can be turned “off”. The return (reflected and backscattered) signal is directed into a photodetector of the OTDR, and is measured from the point in time when the fiber span starts to be illuminated. The measurements are made by sampling the return signal at predetermined time intervals—defined as the sampling rate. The created power samples are then subjected to post-processing in the form of a differentiation operation to create a conventional OTDR trace from the collected data.

Abstract: According to an illustrative embodiment of the present invention, a method for controlling an optical amplifier is disclosed. The illustrative method includes receiving a portion of an input signal to the optical amplifier; receiving a portion of an output signal from a first amplification stage; receiving a portion of an output signal of the optical amplifier; and adjusting the first amplification stage and a second amplification stage based on the received portions to substantially control the optical amplifier. According to another illustrative embodiment of the present invention, an optical amplifier includes a controller which receives a portion of an output signal from a first amplification stage and a portion of an output signal from the optical amplifier. The controller adjusts the first amplification stage and a second amplification stage based on the received portions of the signals.
