Gain Flatting of DWDM/WDM Networks in Long Haul Networks

Abstract

In the conventional amplifier there is two way conversion of the signal which is totally eradicated in the network which no-doubt enhance the overall performance of the DWDM in the long haul networks with the use of the modern optical amplifier. In this paper we optimise the gain of the 8 DWDM channel over entire conventional band i.e. C band. The gain flattening is done with the help of the Gain Flattening Filter (GFFs) as well as DCF. Numerical simulation result shows that both techniques can minimise unevenness of gain in all the prescribed WDM channels.
