We analyze teletraffic capacity performance of a WDM/DS-OCDMA Passive Optical Network. Hybrid WDM/DS-OCDMA PON is proposed to increase user capacity performance and to be a cost effective method per wavelength of a WDM PON. For each prime code used in this system, an appropriate simultaneous capacity threshold has been evaluated in a manner to ensure good transmission performance (BER~10*** 9). Since this capacity threshold is inferior to the nominal resource capacity of the considered code, a soft blocking of the system has been determined even if resources in the system are still available. The teletraffic capacity of the WDM/DS-OCDMA system has been then analyzed under the maximum of soft blocking probability constraint for different prime codes. This value is dependent on the probability of channel activity factor. It is demonstrated that using extended quadratic congruent codes (EQC) with better correlation properties, causes the teletraffic capacity to be closer to the nominal teletraffic capacity.
