Abstract
We put forward the first all-optical optical code-division multiple-access(OCDMA) system with 2 users based on variable code shift keying(CSK). The all-optical exclusive OR logical gate in the system employs the ultrafast performance of optical fiber nonlinear effect and operates without wavelength transforming. In our system, the data rate is 10Gb/s and the transmission distance in optical fiber of G.652 is 20 km. A quantitative analysis of data confidentiality is presented. Compared with other secure systems, our system can greatly improve the confidentiality of the transmitted information.
