Measuring Parameters for Communication Systems.

      Аннотация: 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.
