EDFA booster amplifier C-band DWDM EDFA card

Description

The C-Band DWDM EDFA Booster Amplifier is designed to provide reliable optical signal amplification for DWDM transmission networks. Featuring a stable pump laser, advanced optical circuitry, and intelligent control technology, it delivers consistent optical output performance while maintaining low noise characteristics.

Superior optical performance for digital fiber communication systems. A specialized gain-flattening filter (GFF), combined with an exceptional optical path design, optimizes flatness and noise to the best possible levels.  This DWDM EDFA Booster Amplifier supports 40 to 80 channels with flatness above 35nm.

For network management and system monitoring, the amplifier includes an intelligent MPU-based control platform, OLED display, and LED status indicators. Operators can monitor and manage device status via various interfaces—such as SNMP, Ethernet, and RS-232—enabling seamless integration with existing network management systems.
