  • Optical return loss and receiver reflection

    Optical return loss and receiver reflection

    Return loss measures how much optical power is reflected back toward the transmitter due to imperfections at connectors, splices, or interfaces. In modern networks running at 10G, 100G, or even 800G speeds, poor RL can increase bit errors, reduce system reliability, and shorten. Reflectance (which has also been called "back reflection" or optical return loss) of a connection is the amount of light that is reflected back up the fiber toward the source by light reflections off the interface of the polished end surface of the mated connectors and air. Measured in dB and stated as a positive value, Core Cladding as connector pairs within that link. Return loss (RL) is also called reflection loss. 8, OptiFiber is able to measure optical return loss.
