C Band Single Port EDFA EA-55D

C Band Single Port EDFA EA-55D
  • Summary
  • Features
  • Advantage
    EA-55D 1550nm C Band Gain Flatness Erbium Doped Fiber Amplifier (EDFA) can be divided as pre-amplifier, line EDFA, and power amplifier. It adopts 980nm or 1480nm DFB laser produced by JDSU, Fitel and other well-know world band semiconductor companies as pump source. It is also equipped with the light power output  stabilization  curcuit and temperature stability control circuit for pumping thermoelectric cooler , which ensure best machine performance and long-life laser stability.
