Overview
DIGICAST EDFA series is a low noise, high performance, FTTP high power multi-ports optical amplifier with gain spectrum band within 1540~1563nm. Each output port for optical amplifier has built-in well-performed CWDM. Every external up-link optical port of optical amplifier can connect with OLT very conveniently.
DIGICAST optical amplifier can be compatible with any FTTx PON Technology. It offers a flexible and low-cost solution for CATV large area coverage of metropolises and medium-sized cities. Perfect APC, ACC and ATC control, excellent design in the ventilation and heat-dissipation ensure the long life and high reliable work of pump laser.
Features:
Built-in WDM multiplexer-- mix the PON outputs from the OLTs optional
High Stability and Reliability--The front panel key can set up and modify the device performance parameters to meet different network design requirements
Excellent protection circuit design -- The front panel indicator lights monitor and instruct the running status of device parameters in real time, easy to find problems in time
High Output Power and High Gain---The 2U product supports total output power up to 38dBm, and supports the output power adjustable function with an adjustable range of +0.5~-4dB
Friendly network management interface--support WEB network management and SNMP, WEB interface is rich in functions
Dual power supply-- Dual power supply with one-touch pull-out and hot backup design
