Low-loss 980-nm pump-signal WDMs allow multiplexing of signal and pump in EDFAs and can be supplied in SpecTran SMB-DO980B, Corning Flexcor, Corning CS-980, and Fibercore SM-980 fiber types. Component performance is consistent, and loss is typically less than 0.1 dB. Both C- and L-band versions are available with devices used for operation over both bands simultaneously.
