With the emergence of network driven applications and high speed requirements in communication along with security and large bandwidth, there is a need for a network technique which is capable of providing all the above with a reduced cost. A multiple access technique called Optical Code Division Multiple Access (OCDMA) seems to be fulfilling the above criteria. OCDMA combines the large bandwidth of the optical fiber communication and CDMA technique to achieve the high speed connectivity. The performance of the OCDMA system is reduced due to Multiple Access Interference (MAI). To enhance the performance various detection techniques are used. The software used for simulation is OptiSystem from Optiwave. It has been shown that the bit error rate (BER) is equal to less than 10-9.

Abstract


With the emergence of network driven applications and high speed requirements in communication along with security and large bandwidth, there is a need for a network technique which is capable of providing all the above with a reduced cost. A multiple access technique called Optical Code Division Multiple Access (OCDMA) seems to be fulfilling the above criteria. OCDMA combines the large bandwidth of the optical fiber communication and CDMA technique to achieve the high speed connectivity. The performance of the OCDMA system is reduced due to Multiple Access Interference (MAI). To enhance the performance various detection techniques are used. The software used for simulation is OptiSystem from Optiwave. It has been shown that the bit error rate (BER) is equal to less than 10-9.
