ABSTRACT: In this paper, we discuss and analyze an optical code
division multiple access for multiple user system. Media access control
implementation has been considered. For fulfilling the huge need of bandwidth
services, technology tends to move to optical networks and three major optical
systems come into existence. Code division of the optical network is most used
and real concept interacted with users up to this time. Optical code division
multiple access provides complete spectrum to each and every user for the time
of accessing the channel. In the paper, we have proposed network architecture
with optical encoder and decoder along with optical code translator which is
supporting multiple user systems. We integrate the code translator with
encoding and decoding of optical code to use the optical network at full extent
and present the simulation validation results of 6 Gb/s 3-hop transmission by
use of proposed architecture. Further, we have implemented experimentation with 6
users 3 Gb/s optical code division multiple access network. Through simulation structure,
it is shown that the combination of encoding with EDFA in multiple user
environment system provides improvement in bit error rate and also improves the
multiple access interference. With increase of users in the network, MAI
value increases and our proposed scheme controls interference in
the network.
