In this paper, we use different types of polarization schemes to measure polarization mode dispersion in WDM system and analyse the BER, Q factor and Eye diagram of various channels. We investigate that if polarization angle can be controlled with the help of polarization controller at ellipticity=+45/-450, azimuth= 00 corresponding to right hand/left hand circular polarization then the overall results shows improvement of Q-factor and BER in case of odd and even channels of the system. The polarization mode dispersion in this mode is also lower than other polarization modes.Keywords

In this paper, we demonstrate a FTTH B-PON system with triple play broadcast catv 64-QAM at 1550-nm and voice over ip and high speed internet at 1.25GBPS data link at 1500-nm, downstream configuration with 1:64 splitting and 20-km reach. Our investigations aim at finding the cost effective solutions for fibre-to-the-home (FTTH) network deployment. Ftth b-pon system using 64-QAM shows total attenuation from fiber spans and splitters is about 29.698 dB for data and for video is 29.296 dB and input power to the receiver is about -25.707dBm for data and for video is -25.520dBm. This article follows the progress in moving fiber toward the home using FTTH and major architectural changes that have reduced costs while increasing capabilities to meet today's needs.
