The technique of optical CDMA allows the division of resources and data in the
telecommunications networks optical, in a simultaneous and asynchronous way.
The interest of the optical CMDA is in the use of a broad band-width on the support of
transmission which is the optical fiber.
The transmission of the data in an optical CDMA connection, can be introduce many
limitations that the interference of multiple accesses (IAM), which is result by the products of
inter correlation not nulls of the codes used.
In our work the objective is the evaluation of performance of an incoherent connection
CDMA optical with direct sequence (DS-OCDMA) using the optical orthogonal codes
(OOC), and treat the effect of the interference of multiple access (IAM).
A detailed study of the telecommunications networks optical was being done, with a
description of DS-OCDMA.
The implementation of an optical connection CDMA was be realized by using the
software of simulation COMSIS with an evaluation of its performances.
