Ultra Low Power Pre-EDFA EA55U
  • Summary
  • Features
  • Advantage
    EA55U is a high performance optic signal booster working within 1540~1565nm, Gain (Max.) reaches up to +10dB. EA55U adopts 2-stage amplifying process; first stage uses 980nm pump laser, and post-stage 1480nm. They are from JDSU or Fitel. Optimized perfect circuit design makes it possible to work in best condition, and extend pump lasers life. Module design plug-in Power supply And Built-in NMS module makes it easy to manage and maintain in local and remote by Ethernet network.
