Description:

The paper explains that code division multiple access (CDMA) is a type of communication using multiplexing that help in radio transmission and wireless networks. The paper also explains optical code division multiple access (OCDMA) as a "next generation CDMA" technology which uses fiber-optic technology. The paper describes the method by which optical CDMA systems work and explains the steps necessary to achieve multiplexing. The paper then shows how a CDMA communication system based on optical codes is different from radio and wireless systems and possesses unique attributes and advantages. The paper looks at the various codes that have been designed for use in OCDMA devices and discusses the two categories of OCDMA devices. The paper explores the aspects of OCDMA on which research efforts are being organized and illustrates the technological barriers to the general acceptance of OCDMA devices. However, the paper concludes that OCDMA possesses a number of advantages which make it a promising candidate for the multiple-access networks of the future.

From the Paper:

"CDMA or Code Division Multiple Access is a type of communication using multiplexing. It provides a means of "multiple access to a physical medium". This medium can be a radio channel where a number of users use the medium simultaneously by utilizing different and unique orthogonal code sequences. The CDMA interface is related to the air interface only which is associated with the radio component of technology. CDMA facilitates the operators to offer network features as it finds suitable. CDMA technology best corresponds with data transfer where delays are expected and which possesses "bursty behavior" known as asynchronous data transfer. Various CDMA based technologies have been developed which help in radio transmission and wireless networks."
