Attenuator Application

Generally, multimode systems do not need attenuators as multimode sources rarely have enough power output to saturate receivers. While Singlemode systems, especially short links, often have too much power and need attenuators. Ordinarily collocated with SM transceivers and cables to better stabilize link and realize steady & efficient transmission system.
