Dispersion Compensation in OCDMA system using DCF and Fiber Grating
نویسندگان
چکیده
OCDMA is a technique by which large number of users can access the network simultaneously i.e. at the same time. As the number of user increases, the dispersion and interference begin to rise, which led to high bit error rate and low quality of service of the system. Due to high bit error rate, the transmission of data becomes unsecure and error prone. Therefore to remove or minimize the dispersion in 8 user OCDMA system with single mode fiber, DCF (Dispersion Compensation Fiber) and Fiber Grating technique is used along with the single mode fiber. In this paper, it is shown that with the use of DCF, dispersion is compensated to a large extent in 8 user OCDMA system. The comparison of DCF is made with Fiber Grating according to the results obtained, DCF is found to be better compensator as compared to Fiber Grating.

Chromatic dispersion from optical fiber is the most important problem that produces temporal skews and destroys the rectangular structure of code patterns in the spectra-amplitude-coding-based optical code-division multiple-access (SAC-OCDMA) system. Thus, the balance detection scheme does not work perfectly to cancel multiple access interference (MAI) and the system performance will be degrade...
