EDFA (Erbium-Doped Fiber Amplifier) optical amplifier card developed by GIGALIGHT is specifically designed for long-distance digital optical fiber communication systems in conjunction with dispersion equipment. It features a highly reliable pump laser as its core component and incorporates unique ATC (Automatic Temperature Control) and ACC (Constant Pump Current Control) circuits, ensuring high stability and reliability of output power. With a professionally designed GFF (Gain Flattening Filter) and excellent optical path design, it achieves optimal flatness and noise performance. It supports APC (Automatic Power Control) and AGC (Automatic Gain Control) functions.


  • Supports DWDM systems with C-band optical amplification
  • Supports optional OSC signal input amplification function
  • Supports maximum saturated output power of +23dB, minimum input power of -35dB
  • Supports power amplification, line amplification (second-stage optical amplification), pre-amplification
  • Monitoring capabilities: pump drive current, pump output power, pump switch, pump temperature, input optical power, output optical power, module temperature
  • Supports configurable pump switch, AGC mode, and APC mode (adjustable input and output optical power)
  • Supports optical monitoring port (MON)
  • Supports SNMP-based unified network management platform, with CLI (telnet and console), Web, and NetRiver (graphical interface) management methods.
