1525 nm to 1605 nm, 15 dB Gain, Raman AmplifierOptilab Raman Amplifier Rackmount Units are designed for distributed Raman amplification in both the C Band and L Band. The RA CL3 15 R unit provides over 15 dB On Off gain flattened amplification from 1535 nm to 1609 nm, thus can support up to 200 DWDM channels. Each of the four pump channels is configured with two high power pump laser diodes and one polarization beam combiner (PBC). The unit includes micro controller based laser current control
