The importance of measuring fiber loss and distances

WebAttenuation is the reduction in power of the light signal as it is transmitted. Attenuation is caused by passive media components such as cables, cable splices, and connectors. Although attenuation is significantly lower for optical fiber than for other media, it still occurs in both multimode and single-mode transmission. WebDec 22, 2015 · Its purpose is to detect, locate, and measure elements at any location on a fiber optic link. OTDR works like radar—it sends pulse down the fiber and looks for a return signal, creating a display called a “trace”or …
