1550nm CATV 8PON E/YDFA EA-55XX

1550nm CATV 8PON E/YDFA EA-55XX
  • Summary
  • Features
  • Advantage
    EA-55XX is a fiber amplifier which is especially designed for CATV network. As the EDFA's wavelength is 1550nm, it is in line withhe low-loss band of fiber and its technology has been ralatively mature,so widely used. 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.
