EDFA

[rajkumar gupta]

Hi..everyone
—-I am designing 8/16/32 channels DWDM system.When i used Bandwith of MUX/DMUX from 10GHZ to 100GHZ .the system performance has increased.Why this ishappening? and If i used 100GHz it will be correct or there is any formula to decide the value of bandwidth for MUX/DMUX.
Please help..
—-another problem is ..In 32 channel DWDM system with all compensation techniques or OPC technique, when i used EDFA in between SMF and DCF …it doesn’t give good result but when i remove EDFA ..the performance has increased.What is reason behind this..please clear..because we use EDFA to improve the signal strength but here its opposite..

Hello Rajkumar,
The bandwidth of the MUX/DEMUX is crucial in your DWDM system. Please find attached a paper that discussed this issue that will give you some guidance.
