Today’s high-speed systems are comprised of many highly sensitive components, and great care must be taken to ensure that proper operating conditions are created and maintained. Failure to control optical return loss (ORL) in systems will cause high bit error rates resulting from multipath interference, degraded optical signal-to-noise ratio (OSNR) and transmitter instability. This application note will focus on a detailed description of this phenomenon and on the importance of accurately measuring ORL and identifying its main components.
