HSA4300 series is a low noise pre-EDFA which designed specifically for single wavelength optic transmission system. It is installed in the front of optical receiver, used for improving the receiving sensitivity of the optical receiver, and extending the signal transmission distance.
HSA4300 adopts the world's top class pump laser. Its excellent optic performance, advanced eletronic circuit and low consumption greatly reduced the heat power consumption of whole unit. 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 commutation and SNMP network management port. The laser will switch off automatically if optical power is missing, which offers security protection for the laser. All the optical port can be installed in the front panel, also can be in the back panel if customers specify.
