摘要： An optical channel monitor is formed to include the capability to sense real-time changes in optical power across signal bands (optical power changes including, for example, a complete drop out of the signal band) and quickly measure the resulting spectrum, thus enabling the host to initiate advanced power balancing solutions that mitigate the extent of the power change until a permanent fix is provided. A set of signal band sensors is included with a conventional OCM, where each sensor includes a photodetector that is able to detect changes in operation along its associated incoming signal band. Control electronics are used to monitor the states of the photodetectors, with the ability to invoke an OCM scan of the complete wavelength range when a power change condition is flagged.

摘要： Coherent optical multiplexing 1+1 protection disclosed herein uses multiplexers, each having multiplexing and demultiplexing sub-units. Relay ports of a node are connected with the multiplexers, and each relay port is configured to input and output optical signals with the corresponding multiplexer. Two transmission ports of the node are connected with disjoint paths and are configured to input and output optical signals therewith. The node includes: a first optical splitter having input ports connected with the relay ports and two output ports connected with the two transmission ports; an optical switch connected with the transmission ports respectively via two input interfaces; a second optical splitter, which is a 1×N optical splitter, having one input port connected with an output interface of the optical switch and having output ports connected with the relay ports. The solution is reliable in implementation, has low insertion loss, and has good transmission performance.

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.

摘要： An optoelectronic module includes a housing and a printed circuit board (“PCB”) positioned within the housing. A positioning member is coupled to the PCB and includes one or more receptacles each configured to receive and secure positioning of an optical component relative to the PCB. The positioning member may include a plurality of receptacles positioned relative to one another in an arrangement defining a vertical array of receptacles, a lateral array of receptacles, or both. In one form, an optical component, when positioned in a receptacle of the positioning member, is spaced from the PCB. The positioning member may be formed of a thermally insulative or thermally conductive material, and a number of optical fibers may be routed between the positioning member and the housing.
