Optical correspondence for different access has turn into the standard for scientists as the utility rate in optical correspondence these days is expanding quickly. As different gets to, the more clients uses the system, date rate, limit and security have turn into the discriminating issue for the optical framework. The development of remote correspondence with code-division multiple access (CDMA) system have persuaded the joining of CDMA method into optical system, as it is substantially more alluring since it permits different users in a local area network (LAN) environment to get to the same fiber channel non concurrently at all times. Besides, the power of CDMA method in remote system is yet to demonstrate that OCDMA offers security preferences over other various access frameworks by keeping up the nature of administrations. In this paper, the study on OCDMA is in light of exhibiting an analysis on Optical Spectral-Amplitude Code (SAC) OCDMA organized with uniform fiber Bragg gratings. It shows a three-clients SAC-OCDMA For three-client SAC-OCDMA system working at 1550 nm wavelength with 622 Mb/s information rate and 10 Gchip/s chip rate, the greatest suitable transmission separation for a bit mistake rate (BER) < 10-9 at 50km SMF utilizing RZ group [8].
