Testing in the manufacture, operation and maintenance of optical device assemblies

Abstract From the Canadian patent

To facilitate testing in the manufacture operation, and maintenance of, substrate-supported assemblies such as e.g. optical transmitters and receivers in subscriber-loop and local-area networks an assembly is provided with built-in, optical test features at selected test points. Preferred test features may include side-by-side couplers or reflector taps as may serve to extract or insert light into a substrate-supported waveguide. Testing may further involve the use of a test sethaving optical components in alignment with test features of an assembly.
