Abstract

This paper reports a hybrid system, which is capable to accommodate 96 users using only 8 optical CDMA codes carried by 12 WDM channels spaced by 25GHz. A user’s data at rate of 5Gbps, and 40Gbps per channel is achieved and transmitted over 93.4km of optical fiber. The simulation results verified that the concept of CDMA technology has the ability to reduce the four-wave mixing (FWM) nonlinear effect since the energy of a bit is spared over chips sequence. In addition, the results revealed that longer code length is recommended to have better bit error rate performance under the impact of FWM effect. Moreover, the squeezing of the chip interval into 25% of bit duration guarantees the avoidance of inter-symbol interference (ISI).
