    Abstract: Raman amplifier systems and methods with an integrated Optical Time Domain Reflectometer (OTDR) for integrated testing functionality include an amplifier system, an OTDR and telemetry subsystem, and a method of operation. The OTDR and telemetry subsystem is configured to operate in an OTDR mode when coupled to a line in port and to operate in a telemetry mode when coupled to a line out port. The OTDR and telemetry subsystem enables on-demand fiber testing while also operating as a telemetry channel that is both a redundant optical service channel (OSC) and provides a mechanism to monitor Raman gain over time. The OTDR and telemetry subsystem minimizes cost and space by sharing major optical and electrical components between the integrated OTDR and other functions on the Raman amplifier.

    Abstract: The present disclosure relates to streamlining optical module and/or subassembly development, manufacturing, and testing through introducing a memory component within a module and/or subassembly that is utilized with a host module for system calibration and/or configuration. In an exemplary embodiment, the present invention can streamline optical amplifier (EDFA) module and/or subassembly development, manufacturing, and testing. The present invention includes an optical module/sub-assembly without control circuitry, i.e. a “dumb module”, but with a memory that is used to load relevant data from a supplier. This data is utilized to calibrate, test, and configure the optical module/sub-assembly in a host module. The host module includes control circuitry to access this memory in the optical module/sub-assembly and to calibrate, test, configure, and control the optical module/sub-assembly. Advantageously, this additional memory reduces manufacturing time without the disadvantage of adding complexity in the optical module/sub-assembly.

    Abstract: The present disclosure provides high-degree reconfigurable optical add-drop multiplexing (ROADM) systems using bi-directional wavelength selective switches (WSSs) and optical circulators. A single WSS is utilized on each degree of a node in a bi-directional manner, i.e. both ingress and egress share the same WSS. Advantageously, the present invention eliminates conventional splitters/combiners thereby capping intra-node insertion loss to a certain value regardless of the number of degrees. More importantly, the present invention reduces noise penalty associated with high-degree nodes while minimizing cost.
