TX ORL (Optical Return Loss) tolerance is specified as 12dB in D3. 0 - leveraged from previous generation specs. By adopting the same level of RX reflectance and TX ORL tolerance as 50G. Beginning with software release 1. 8, OptiFiber is able to measure optical return 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. The word “loss” sounds like something that should be as small as possible, but return loss works differently.
