Gives Telcordia's view of proposed generic reliability assurance requirements for passive fiber optic branching components like splitters, couplers, and wavelength division multiplexers (WDM-DEMUXES). Sets forward criteria to form a minimum set of reliability assurance practices that Bellcore see as necessary for the overall performance and reliability of the telecommunications equipment using these components.
