Abstract

This paper introduces an Optical Code Division
multiplexing (OCDMA) system using two code keying
encryptions. In this paper proposed OCDMA system is designed
using Semiconductor optical amplifiers (SOAs) which has
nonlinear character and can implementor different logic
functions. SOA based 2 × 1 Codeword Multiplexer (CMUX) is
designed to multiplex the user data and a 1 × 2 Codeword DE
Multiplexer (CDEMUX) to demodulate the user data. Then a
multiple user access is provided using WDM system to design the
whole OCDMA system. Transmission distance of 70 km is
achieved with acceptable bit error rate and Q factor. Open eye
diagram is also verified at the receiving end.
