1540 nm to 1575 nm, 18 dB Gain, Raman AmplifierOptilab Raman Amplifier Rackmount Units are designed for distributed Raman amplification in C Band. The RA C3 18 R unit provides over 18 dB On Off gain flattened amplification from 1540 nm to 1575 nm, thus can support up to 50 DWDM channels. Each of the two pump channels is configured with two high power pump laser diodes at 1444 and 1462 nm and one polarization beam combiner (PBC). The unit includes micro controller based laser current control
