DRA module SPEC

The amplifier modules can be operated at constant pump power (Automatic Pump Power Control, APPC).

Product Introduction

This document specifies the requirements of a C-band distributed Raman amplifier. The amplifier modules can be operated at constant pump power (Automatic Pump Power Control, APPC). Different wavelength pump power can be adjusted to achieve smooth gain spectrum for the DWDM network application.  It can amplify the single channel signal, in order to achieve the best OSNR; the module integrated a narrow band filter to suppress the ASE power.
