HWA4400|Zhejiang GT Lasers Tech. Co., Ltd.

GT LASERS HWA4400 series is a fixed gain EDFA which is specifically designed for C-Band DWDM optic transmission system, accord with various communication technology requirements of 44 channels DWDM system. It adopts nowadays excellent optical performance, advanced electronic control technology and complete software functionalities. Excellent total integration electronic transient control technology ensures amplifier to achieve the locking of optimal flat gain (OFG) in large dynamic input optical power range.

HWA4400 adopts the world's top class pump laser; advanced electronic circuit and low consumption design, greatly reduced the heat power consumption of complete equipment. Perfect FGC, ATC control, excellent design in the ventilation and heat-dissipation, ensures the long life and high reliability work of pump laser. The LCD at the front panel offers the work index and warning alarm of all equipment. RS232 and RJ45 offer serial communication and SNMP network management port. The laser will switch off automatically if optical power is missing, which offers security protection for the laser.

HWA4400 is suitable for DWDM booster amplifier (BA) and DWDM preamplifier (PA).
