One of Bell Communications Research's (Bellcore's) functions is to perform technical analyses of fiber optic transmission systems on behalf of its clients. One segment of those technical analyses is to determine the expected steady-state reliability performance of a system and compare it to Bellcore's objectives. This paper discusses the methodology Bellcore uses to model the reliability of fiber optic transmission systems. The paper begins by discussing Bellcore's reliability objectives applicable to short haul, interoffice, fiber optic transmission systems for telephone company intra-LATA applications. The paper then discusses modeling the reliability of the electro/optic hardware modules, which is calculated using the component base failure rates, while considering the expected level of quality, burn-in, electrical stress, and probable environment. The paper next discusses techniques appropriate for modeling current system architectures and protection arrangements. These models lead to the calculation of steady state system reliability parameters such as the contribution to service unavailability due to hardware reliability failures. Finally, the results of a system reliability model calculation are shown with a comparison to the objectives.
