A novel optical code-division multiple access (OCDMA) transmission system with all-optical exclusive xor encryption architecture is proposed and demonstrated. This all-optical system conducts OCDMA code swapping based on xor operation. This multilayer approach eliminates radio-frequency data radiation and improves the confidentiality of the transmission system.
