Abstract

The crosstalk performance of coherent time-spreading OCDMA system based on superstructured fiber Bragg grating (SSFBG) is investigated with different input pulse width and grating refractive index modulation amplitude, and corresponding bit error rate (BER) performance was considered at different data-rate. Simulation results show that the crosstalk performance will be degraded with the increasing of input pulse width or grating refractive index modulation amplitude. Moreover, with fixed code length N = 127 and receiver bandwidth limitation, lower data-rate system has better tolerance to the increasing of input pulse width, while higher data-rate system has better tolerance to the increasing of grating refractive index modulation amplitude.
