WebThe two important parameters for the optical performance of fiber connections are insertion loss and return loss. The insertion loss in dB is derived by multiplyin g -10 by the log of the transmission coefficient T, i.e., -10 log(T). Here, T denotes the ratio of transmitted light power to incident light power at the fiber connection. Similarly, the WebSo return loss meters are commonly used for for acceptance work. Some ORL meters can use automation to work as a pair, and measure return loss each end of a system while …
