EDFA (Erbium-doped Optical Fiber Amplifer)

What is WDM EDFA?

  An erbium-doped fiber amplifier (EDFA) is a device that amplifies an optical fiber signal (from CATV).  An WDM EDFA is used to integrated 1550nm CATV (optical signal) and 1490nm /1310nm data stream from the PON into single fiber transmission.

  EDFA-1550W series high power single mode EDFA is characterized with low noise, high linearity. Build-in well-performed CWDM integrated 1490nm /1310nm data stream from the OLT and ONU into single fiber transmission through EDFA, reducing component count and improve system performance and reliability. 

  EDFA-1550W series adopts single mode pump, EDF and multi-pumps integration technique. Optimized for low noise, allow for clear transmission of video, voice and data signals. Its noise figure and reliability is much better than Double-clad Yb/Er Amplifiers. 

  • EDFA-1550WA: 1U chassis, total output power >1000mW, 8 uplink optical ports, for OLT+8 1550nm output optical port, multiply 1310/1490 data stream.
  • EDFA-1550WB: 2U chassis, total output power >4000mW, max. 32 uplink optical ports, for OLT+32 1550nm output optical port, multiply 1310/1490 data stream.

EDFA Application

EDFA is an optical repeater device that is used to boost the intensity of optical signals being carried through a fiber optic communications system. An optical fiber is doped with the rare earth element erbium so that the glass fiber can absorb light at one frequency and emit light at another frequency.
