Overview:

The RED-C Sentior 2180 Gain Switched VG EDFA is based on a novel patent protected concept utilizing optical switches and lengths of un-pumped EDF which act as saturable absorbers. This design achieves a total gain range of up to 32 dB, with NF better than 6dB for all gains. In comparison, a typical VOA based VG EDFA can only achieve a gain range of up to 15 dB, which is usually accompanied by a few dB deterioration in NF at lower gains. Thus, the Gain Switched VG EDFA provides an excellent solution for applications requiring a single type of VG EDFA to cover a very wide gain range.
