Abstract– In this paper, the performance of simultaneous transmission of 4 channelsusing 16 QAM OFDM Passive Optical Networks. The 4 channels transmit the datasimultaneously over single fibre link. The performance is evaluated for 100 km fibreand results are compared with the different length of transmission. The systemhas been evaluated using BER calculations and Q-Factor values. An acceptableperformance over a link length of 100 Km is observed for this transmissionscheme.
