The LambdaDriver® EM1600-OAR modules use an advanced Raman technology for optical signal amplification, used in large capacity digital communication and long-haul broadband DWDM networks. These modules extend the single span reach by at least 50 km in comparison to the conventional EDFA type amplifi ers. Raman amplifi ers also improve the Optical-Signal-to-Noise-Ratio (OSNR) in amplifi ed long-haul networks because they do not introduce noise whereas typical EDFA amplifi ers have a nominal noise figure of about 5.5 dB.
