C-band (* Note 1) erbium doped fiber Pre-amplifier (PA amplifier for short) is an amplifier specially used for weak optical signals in the range of - 45dbm ~ - 25dBm. The typical gain of small signal is as high as 35 ~ 45 dB and has low noise figure. It is usually used before a photodetector to improve its detection ability for weak optical signals.

*Note 1: This EDFA product can be used to amplify any single or multiple wavelength signals within its operating wavelength range, but the flatness of the gain spectrum is not considered when multiple wavelength signals are input. As shown in the figure on this page, the EDFA-C-PA-35 small signal amplifier can achieve high-gain amplification for input signals of different wavelengths within the C-band (note that multiple wavelengths in the figure are not simultaneously input into the EDFA). When the input power of a single wavelength is -35dBm, the effective gain is greater than 35dB, and the signal-to-background noise ratio of the amplified signal is greater than 30dB.
