GAO-WOA-103

Description

Overview

GAOTek EDFA C Band Pre Amplifier is designed for amplifying optical transmission system and supports Single wavelength application in Pre Amplifier and C-Band Multi wavelength application. It is used to regenerate optical signals at C-band without optical-electrical-optical conversion, and can further extend the transmission distance of signals.It is an Erbium doped fiber amplifier service board that supports both WDM and SDH/ PDH transmission systems. Also with this type of amplifier, WDM transmission can be achieved by using DWDM multiplexer or de-multiplexer, which is especially suitable for long-distance trunk line networks. The Amplifier is also suitable for MAN (metropolitan area network), access networks and various SDH/PDH transmission systems.

Features

  • Supports amplification through two stages. OADM or DCM modules can be accessed in the middle.
  • Supports Single as well as Multi Wavelength Applications.
  • It also supports adjustable gain but this is an optional feature.
  • The Amplifier supports both high and flat gains.
  • Parameters can be set and viewed in the graphical interface.
  • It has low noise so that there are fewer disturbances.
  • ACC, APC and AGC are optionally supported features.
  • Compact structure and modular design which supports hot plug.
