WebOptical Return Loss What Is Return Loss? Return loss (RL) is also called reflection loss. When high-speed signals enter or exit a part of an optical fiber, such as an optical fiber connector, discontinuity and impedance mismatch may cause reflection, which is the return loss of an optical fiber. xxxxxxxxxx WebMay 10, 2024 · Return loss. On the contrary, return loss refers to the loss of signal power when going back from point B to A. When the impedance is too high, the network simply stops working, shutting down the signal transmission. To avoid most of the return loss, operators know they should always use angled ferrules when working with optical fiber.
