Fiber optics-failure modes and mechanisms

A study was conducted to investigate the frequency and cause of failures of fiber-optic transmitters, waveguides, receivers, connectors, and splices. To accomplish this, quantitative and qualitative data were collected and evaluated to determine why and when failures occurred and to identify design options which can be made to avoid these failure conditions. An understanding of fiber-optic device failure modes and mechanisms is critical to insuring unit reliability, improving the manufacturing process, and allowing design flexibility of the overall fiber-optic system. The author summarizes the specific failure modes uncovered for typical items such as transmitters, receivers, fiber, cable, connectors, and splices. He also discusses fiber-optic performance criteria, design considerations, failure rate data, and failure mode information.<
