EDFA

 

The product 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 is specially designed for digital optical fiber communication system including:(1)lower noise figure;(2)high output booster and high sensitivity Pre-Amplifier improve the system loss budget(3)Broad input power range and output power adjustable make it use easily

The design of dual power mixed hot swap make it has longer MTBF. Also the power system can be backup.

Employ the intelligent temperature control system, the fan is on when the module temperature above 45, meanwhile it will stop as the temperature is below40, which ensure the thermal stability and fan life-time. Professional air duct design ensure the best temperature stability.
