Up to +37 dBm Integrated Pre-Amp EYDFA, Big ModuleThe Optilab EYDFA XX PA BM is designed to amplify optical signals up to 37 dBm average power for high power applications at 1550 nm wavelength range. The EYDFA XX PA BM incorporates two stages of amplification based on multi mode pumping technology using Er Yb double clad fiber. The optical gain of the amplifier exceeds 35 dB via the EDFA pre amplifier, which allows a low input signal level of 20 dBm. The Preamplifier is connected via external
