1550nm EDFA Module for Optical Distributed System
This optical amplifier is high stability output EDFA. The key components of the product are high reliability PUMP laser. A unique APC (Automatic Power Control), AGC (Auto Gain Control) and ATC (Automatic Temperature Control) circuit insures the high stability and reliability output power or Gain, the unique optical circuit design ensures the excellent optical performance. The high stability and high precision MPU system to ensure the control, adjustment and monitor are intelligent and easy.
The optical circuit design especially for Analog CATV system as follows: (1)Low noise ensure better CNR for Analog system is sensitive for noise. (2) Good Spectral flatness in the operating signal to ensure better CSO. (3) Good Spectral flatness in whole C- bands to fit the upgrade in future NGB.
