This paper presents a performance evaluation based on elaborated analytical expressions of error probability for broadband access network in the case of a combined technique of Dense Wavelength Division Multiplexing (DWDM) and One Dimensional Optical Orthogonal Codes (1D-OOC). Optical sources with relatively large spectrum has been considered and simulated. Besides the Multiple Access Interference (MAI) at the receiver due to the access method which is Optical Code Division Multiple Access (OCDMA), the emitted radiation of these sources in a dense WDM communication link introduces additional interference. Conventional Correlation Receiver (CCR) and Parallel Interference Cancellation (PIC) receiver limitations are discussed.
