Security as well as capacity in optical transmission link could become a critical issue for some applications such as military networks or enterprise networks. The security sensitive data such as military transactions, financial transactions, medical records, intellectual property etc., which is to be securely transmitted, is done through the internet. The exponential growth in information throughput on the internet increases the transmission of confidential and commercially sensitive data through optical networks. With this, the potential risk of security of this valuable information also increases as tapping of the optical signal from a fiber could be easily done by using inexpensive equipment. Physical layer security is thus becoming an impelling request in the next generation of optical networks. OCDMA technology is an attractive solution for these applications since it provides format-independent security in physical layer while guaranteeing appreciably wide bandwidth. Enhanced information security is often said to be inherent in OCDMA technology due to its coded nature.
