OCDMA over conventional TDM PON leads to increase access network capacity by multiplexing TDM signals with OCDMA codes. We propose a novel sourceless ONU for OCDMA-TDM PON within a centralized light source placed at OLT. Sparser and longer extended quadratic congruence (EQC) codes with good correlation properties are used as optical CDMA en/decoders. However, multiple access interference (MAI) can limit the number of simultaneous users in this system. We analyze BER performance of sourceless OCDMA-TDM PON using four different EQC codes. Finally, network scalability and throughput performance of the proposed scheme are analyzed. These analyses over OCDMA-TDM PON show an upgrade of bandwidth and network capacity with an advantage of sourceless ONUs compared to the conventional TDM PON.
