Return Loss (RL) measures how much optical power is reflected back toward the transmitter. Excessive reflections can destabilize lasers, increase noise, and degrade system performance—especially in high-speed or analog networks. What Is Return Loss? Return Loss is calculated as: RL = –10 log (Preflected / Pinput) Higher return loss values indicate lower reflection and better performance. Typical […]
