A new technique invented to suppress the four wave mixing (FWM) effects in spectral amplitude coding (SAC) optical code division multiple access (OCDMA). This technique based on adding idle code at the sideband of the code construction to generate the virtual FWM power at the sideband of the signal, and then filtering these virtual FWM power from the original FWM power in the system. Moreover, in terms of cost, the reported technique is considered a cost-effective as the LED light source is used to generate the sideband codes. In this paper, this technique applied for multi weight (MW) code as an example of SAC-OCDMA codes. The results showed that after suppression the FWM power, the BER get better performance in the system, for example, the BER value before using the technique is 1.4 × 10-11, and after using the technique is 4.4 × 10-19.
That was the Abstract of my paper that I will publish it for international Conference preferably IEEE Conference in the future.
