MetroWAVE-EDFA DWDM EDFA Optical Amplifiers

DWDM EDFA Optical Amplifiers

MetroWAVE-EDFA optical amplifiers provide multi-function, low noise, Erbium-Doped Fibre Amplifier (EDFA) solutions that are ideal for metro Dense Wavelength Division Multiplexing (DWDM) applications.

EDFA Optical Amplifier

EDFA Optical Amplifier & DCM Dispersion Compensation Device Application
  • Three Optical Amplifier C-band applications
    • Booster Amplifier
    • In-Line Amplifier
    • Pre-Amplifier
  • Metro DWDM distance extension
  • Output power levels from 13 ~ 22dBm supported
  • Gain of 8 ~ 33dBm supported
  • Low noise figure: typically 5dB
  • Flat Gain (<1dB variance) over the entire amplified band
  • Optional mid-stage port for dispersion compensation device

The MetroWAVE-EDFA family of C-Band EDFA Optical Amplifiers is part of the MetroWAVE family of fibre networking products. Product variants are available to support the amplifiers required for long haul DWDM networking.

  • Booster amplifiers maximise the available transmit power, supporting high input powers, high output powers and medium optical Gain. Boosters are designed to amplify aggregated optical inputs from DWDM multiplexers.
  • In-line amplifiers perform a repeater function in the middle of an optical link, supporting medium to low input powers, high output powers and high optical Gain, with a low noise figure.
  • Pre-amplifiers maximise the available receiver power, supporting medium to low input powers, medium output powers, and medium Gain.

Whilst Metrodata's fibre product ranges use industry standard user exchangeable SFPs, it is recommended that these are purchased from Metrodata to guarantee their specification and compatibility with each other. For all fibre transceivers including vendor compatible SFP, SFP+, XFP, X2 and XENPAK transceivers, with long distance, CWDM or DWDM specifications then please contact our Sales Team with your requirements.
