Abstract

Optical Code Division Multiple Access (OCDMA) systems are parts of a multiple access scheme that allows multiple users to share a common fiber. OCDMA utilize codes depicted by optical spectra/spatial. There are various types of OCDMA codes. The most typical OCDMA code used are Double Weight (DW) family code. DW family code consists of Modified Double Weight (MDW), Enhanced Double Weight (EDW) and recently developed Flexible Double Weight (FDW) code. Each code has its uniqueness in terms of code weight, basic code users and code length which contributes to the Bit Error Rate (BER) and signal quality at the receiver. The newly proposed system is the Hybrid FDW/EDW code, which combines FDW and EDW codes using the polarization technique. DW family code is considered a non-hybrid system in this research. According to the results, Hybrid systems outperform the non-hybrid system in terms of BER and transmission distance. Hybrid FDW/EDW systems can reach up to 80 km, non-hybrid FDW can reach 60 km, and non-hybrid EDW can reach 50 km. This combination using polarization extends the transmission distance, increase the number of users and support high data rates for the hybrid systems.
