Optical Code Division Multiple Access

Free Space Optical (FSO) Communication is the technology in the optical communication system in which the light travelling in free space is used to transmit data wirelessly for computer networking or telecommunication. Several years ago Optical code division multiple access (OCDMA) systems have proven to be a helpful in combining the flexibility of CDMA technique with unlimited bandwidth of fiber to achieve high speed connectivity with high quality of transmission. It combines the large bandwidth of optical with the flexibility of the CDMA technique to achieve high speed connectivity.
