The product is a high stability output power EDFA. The stability Pump Laser and unique ATC (automatic temperature control)
and AGC (automatic gain control) circuit are employed in it as the key components to ensure the high stability and reliability
of output power. The unique optical circuit design ensures the excellent optical characteristics. The high stability and high
precision MPU system are employed to ensure the control adjustment and display are intelligent and user-friendly.
The optical circuit is designed especially for digital optical fiber communication system including:
(1) lower noise figure
(2) the high output booster and high sensitivity pre-amplifier improve the system loss budget
(3) Broad input power range and output power is adjustable easily.
Employing the intelligent temperature control system, the fan is on when the module temperature over 35℃, and it will stop
when the temperature goes under 30℃, which ensures the thermal stability and fan’s long life-time, moreover, the professional
air flow design can also ensure the best temperature stability.
