Multi-Wavelength and Built-in Test Capable Local Area Network Node Packaging

The program goal is to demonstrate the feasibility of building a low-cost, easy to use, wavelength division-multiplexing (WDM) engine that incorporates built-in test (BIT) functions, specifically optical time domain reflectometry (OTDR). This modular WDM engine with BIT will utilize compact, volume manufactured plastic connector body and glass optical elements that integrate all the wavelength splitters and combiners into a robust optical path. The optical path is coupled to lasers and detectors via Ultra Communication, Inc. high-resolution optoelectronics packaging to form the wavelength specific transceiver lanes and OTDR functionality. The modular design approach permits inclusion of this device into WDM nodes such as emerging CLR-4, COBO and SAE Aerospace standards or proprietary, application specific non-blocking, low latency CWDM crossbar switch fabrics.
