摘要： A system for communicating supervisory information between amplifier nodes in an optical communication network utilizes modulation of an included pump source to superimpose the supervisory information on data signals (typically customer data signals) propagating between the amplifier nodes transmitted customer signals. The modulated pump appears as a modulated envelope on the amplified data signal exiting the amplifier node, and may be recovered by suitable demodulation components located at the second node (i.e., the destined receiver of the supervisory information). The supervisory information may include monitoring messages, provisioning data, protocol updates, etc., and is utilized as an input to an included modulator, which then forms a drive signal for the pump controller.

摘要： A system and method for communicating supervisory information between amplifier nodes in an optical communication network utilizes modulation of an included pump source to superimpose the supervisory information on through-transmitted customer signals (or ASE associated with the amplifier if no customer traffic is present). The supervisory information (which may include monitoring messages, provisioning data, protocol updates, and the like) is utilized as an input to an included modulator, which then forms a drive signal for the pump controller. In a preferred embodiment, binary FSK modulation is used.

摘要： A colorless mux/demux cable assembly, including a first fiber optic cable, a second fiber optic cable, and a main body that includes an N:1 optical combiner and a 1:N optical splitter. The N:1 optical combiner is configured to combine individual optical signals received by each of N input fibers of the second fiber optic cable and provide a combined output signal to an output fiber of the first fiber optic cable. The 1:N optical splitter is configured to split a combined input optical signal (having N wavelength channels) received via an input fiber of the first fiber optic cable and provide a split output signal comprising each of the N wavelength channels to each of N output fibers of the second fiber optic cable.

摘要： 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.
