STN6200-RA is a backward transmission signal amplifier by using Raman effects. This product can be widely used in SDH, DWDM and long-distance transmission scenario. It can both amplify optical signals, and improve the OSNR (Optical Signal-to-Noise Ratio) of the system and greatly extend the transmission distance.
