Analysis of OCDMA Link using OHL Based Technique at 1550nm

Abstract

Researchers have looked at multiuser detection as a way to improve OCDMA connection performance over single-user detection. When transmitting binary data via an optical fibre, everyone uses amplitude shift keying (ASK), particularly for on/off keying modulation. The encoder applies a sequence coding to the binary data. Correlation at the end receiver makes it possible to obtain data by using a user-specific sequence code. The incoming signal is checked by the comparator against a predetermined threshold before any data recovery operations are performed. In our current research the performance investigation of OCDMA link is carried out at 1550nm Wavelength using OPTSIM Software version 8.2. The Data rate of 15Gbps is used for investigation purpose of the link. OHL and ON based techniques are used to calculate link evaluation. It has been significantly noted that the performance of ‘ON’ based link is much better than ‘OHL’ based systems.
