Performance Analysis of Receivers in WDM for Extended Reach Passive Optical Networks
Abstract
In this paper we have investigated and analyzed the performance of receivers for different classes of WDM PON system for next generation Passive Optical Networks. The performance is analyzed using Manchester coding for different receivers using various data rates and various fibre distances at the optical network unit in a 32 user WDM PON and DWDM PON. The experimental results are analyzed using the parameters BER, Qfactor and Eye Pattern. The simulation results revealed that the performance gain of around 2.5 Gbps in terms of data carrying capacity per user over a distance of could be achieved if APD receivers are used in the receiver side downstream direction.
