Abstract

In this paper, two different configurations to enhance the system confidentiality in a multi-user environment are presented. All-optical scrambling, based on optical code division multiple access (OCDMA) encoders, is used to prevent signal decryption from unauthorized users. Eye diagrams and BER measurements are also presented to describe the systems performance.
