Abstract

In this paper, we analyze the performance of a hybrid optical time division multiplexing (OTDM) system with optical code division multiple access for spectral amplitude encoding (OCDMA), using very narrow filters with fiber Bragg gratings to the system as encoders and decoders in the transmitter and receiver. The performance of the system depends on variables such as: the length on kilometers of the fiber, the number of users, the bandwidth of Fiber Bragg Gratings, and the application of the Walsh Hadamard (WH) codes. The performance of the system is evaluated through the Quality (Q) factor and Bit Error Rate (BER) with different simulations, a comparison of the WH codes and the impact with the number of users is demonstrated.
