Optical Code Division Multiple Access (OCDMA) using Double Weight (DW) codes for local area network

This paper describes the performance evaluation of the Optical Code Division Multiple Access (OCDMA) technique using Double Weight (DW) Code. This technique was implemented in local area environment which is applied in ring network and the performance analysis was carried out using optical communication simulation software. Details of the simulation result on OCDMA in terms of bit error rate (BER), power received and eye pattern are demonstrated and discussed.
