EDFA-C-PA-Flat Gain

 Erbium-doped Fiber Amplifier EDFA

Multi wavelength/Multi channel, 1540nm~1565nm(C-Band)

It can simultaneously amplify multiple wavelength signals in the C-band and keep the gains between the wavelengths consistent.

Pre - Amplifier PA :  Preamplifier, for amplification of small optical signals in the range of -45 ~ -25 dBm, with a typical gain of 35 dB;
