During the past few decades, the world has seen astonishing changes in the communication system due to advancement in technologies. Communication is a significant part of our everyday life. The increase in usage of multimedia services such as voice, images data, video and data communications requires great transmission capability. In optical communication, the channel (optical fibers) plays a vital role.Here we will discuss a commun-ication system that uses optical fibers. From a security point of view, these quick developments in information services must be secured from attacks. Subsequently, network security concerns have now been increased because of the immense measure of data that streams in a communication media. The exponential development in information throughput on the Internet demands the transmission of sensitive and confidential information over the optical networks. With this development, the possible risks of security of this sensitive data additionally increased as the tapping of the signal from an optical fiber could be effectively done by utilizing then expensive hardware. OCDMA is a technique which can be used to eliminate the problem of multiple user access and traffic growth on the web in optical systems. This paper will review the concepts of OCDMA, including its components, advantages, disadvantages, and different security concerns.
