  This work 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. This paper has investigated the kind
of optical sources with large spectrum bandwidth which could be accepted for a
targeted bit error rate (BER) and given number of users in broadband access
network supporting DWDM with optical orthogonal codes.
