Development of Optical Code Division Multiple Access (OCDMA) for Local Area Network (LAN)

Abstract

Nowadays, communication is very important at any place, time and situation. The transmission of the signal can be in wireless or cable. There are three type of division multiple accesses that use in communication system which are Time Division Multiple (TDMA), Wavelength Division Multiple Access (WDMA) and Code Division Multiple Access (CDMA). CDMA has been recognized to provide efficiency, security, and multi-access benefits in wireless communication. This has triggered interest in providing similar advantages for optical communication systems. The technology of optical fiber telecommunication is developing rapidly. Optical code division multiple access (OCDMA) is an interesting subject of research because of its proposed as a natural solution to achieving asynchronous, high-speed connectivity in a local area network environment. The performance of any OCDMA system strongly depends on the code properties. The application of codes had been develop need to be improved to get the good transmission performance in OCDMA system. Optical CDMA is shown to be competitive with other networking technologies such as WDMA and TDMA, but has the benefit of more flexibility, simpler protocols, and no need for centralized network control.
