Performance Analysis And Improvement Of (2-10) Gbps WDM PON using EDFA amplifiers

In this paper, we have investigated a data transmission of 2 to 10 Gbps WDM PONs with 32 ONUs and single EDFA amplifiers, using optisystem software, and designed such transmitters in terms of fiber length, power of continuous wave(cw) laser, data rate and number of users. We have focused on how to achieve appropriate Q-factors and bit error rates, by analyzing the performance on the basis of transmission distance from 5 to 100 km in terms of Q-factor, minimum BER and output power. When dispersions are lowest and ONUs number is highest, EDFA-EDFA provides better Q-factors, and lower BERs and output powers.
