1U 1550nm CATV Fiber Amplifier EDFA PON EDFA

Product Details

Product Introduction

This optical amplifier is high stability output EDFA. The key component of the product is the high reliability PUMP laser. A unique APC (Automatic Power Control), AGC (Auto Gain Control) and ATC (Automatic Temperature Control) circuit ensure the high stability and reliability output power or gain, and the unique optical circuit design ensures the excellent optical performance. The high stability and high precision MPU system ensure that the control, adjustment and monitor are intelligent and user-friendly.
The optical circuit design characteristics, especially for Analog CATV system, are shown as below:
(1) Excellent CNR performance with low noise for Analog system which highly concerns noise.
(2) Good Spectral flatness in the operating signal which ensures better CSO.
(3) Good Spectral flatness in whole C-bands allows the future upgrade in NGB.
