WebThe power loss of the reflected or returned signal is the return loss which refers RL. Insertion loss is mainly to measure the resulting signal value when the optical link encounters loss, and return loss is to measure the loss of the reflected signal when the optical link encounters component access. Calculation formula: RL = -10 lg (P0/P1 ... 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.
