Product Description

Product Introduction

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. Professional design GFF (gain flattening filter) with excellent optical path design make flatness and noise reach the best optimization. It can provide 40~80 channels, and flatness above 35nm.

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.
The design of dual Power Mixed and hot swap provides longer MTBF. Also, the power system can be backed up.
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.

Intelligent network management system. Perfectly network interface: Ethernet, RS-485 and RS-232 network interface，and the open mib ensure the connectivity with all other network management systems.
