Code interception technology for spectral phase-encoded OCDMA system by using super-structured fiber bragg grating (SSFBG)

The code interception of spectral phase-encode optical code division multiple access (OCDMA) system is studied. A theoretical model of code interception based on SSFBG is presented and then the eavesdropping principle is also analyzed in theoretically. The result of eavesdropping is simulated by Optisystem3.0 and Matlab7.1. The simulation results have shown that the information of spectral phase-encoded OCDMA system can be eavesdropped effectively by using this model.
