9000EDFA-D, 9000EDFA-B, 9000EDFA-L & 9000EDFA-P

Erbium Doped Fiber Amplifiers

The 9000EDFA series are high quality, erbium doped fiber amplifiers used to extend signals in long haul optical communications applications. Available in boost, inline and pre-amp configurations, the different models cover various transmission scenarios at points all along the optical communications path. Combined with Evertz optical transmitters, receivers and DWDM multiplexing products, the 9000EDFA series amplifiers offer a complete solution for long haul signal transmission.


  • Low noise figure
  • Low power consumption
  • Wide operating wavelength range
  • 9000EDFA-P pre-amplifier has high input sensitivity for amplifying weak signals at the end of the optical path
  • 9000EDFA-L inline amplifier combines high input sensitivity and high output power for amplifying optical signals at points within a long haul path
  • 9000EDFA-B boost amplifier provides high optical launch power at the beginning of a long haul path or optical distribution system
  • 9000EDFA-D-AGC may be used as an inline or pre-amplifier. It contains a gain flattening filter for use in DWDM systems with high channel counts and multiple hops. Automatic Gain Control (AGC) allows the unit to respond dynamically to changes in the optical input power and/or number of carriers

* 9000EDFA is strictly for DWDM applications
* 9000EDFA to be used ONLY in Single Mode Fiber applications
* Always consult Evertz for applications assisstance when specifying EDFAs
