Measuring Parameters for Communication Systems

Aim of this book is to analyze the performance of RAMAN EDFA and SOA amplifiers separately at 10 Gbps data rates for 60 channel WDM systems up to a fiber length of 280 km. Depending upon the results the performance of the 3 amplifiers has been compared. It is observed that RAMAN Amplifier provides the better result in terms of Q factor up to a fiber distance of approximately 20 km and in terms of BER up to a distance of approximately 40 km among all the 3 amplifiers. EDFA starts providing better Q factor after a fiber distance of approximately 20 km and better BER After a fiber distance of approximately 40 km among all the 3 amplifiers. But power received is minimum in case of RAMAN Amplifier. In terms of power received SOA provide better result up to a fiber distance of approximately 120 km after that EDFA provide better result in terms of power received among all the 3 amplifiers. Finally the Eye diagram has also been analyzed.
