CO-OFDM is a very attractive modulation and multiplexing technique that is used in wideband optical systems as well as optical wireless systems. Several advantages of optical orthogonal systems is good efficiency of spectrum utilization and channel robustness. Number of small subcarriers is used to transmit data from one source and generally termed as multicarrier transmission. OFDM, a modulation as well as multiplexing technique is the origin of several telecommunications standards counting DTT and radio broadcasting. OFDM is even the source of nearly all DSL standards, and within this situation OFDM is generally known as discrete multitone (DMT). Regardless of the benefits offered by OFDM and its prevalent usage in wireless communications, it has been considered for optical communications during the last years. OFDM is a technique in which sequential data tributary transformed into parallel stream. The concept of OFDM is to divide the broadcast bandwidth into a number of orthogonal subcarriers in order to transmit the symbols using these subcarriers in parallel.In this paper, description of OFDM systems their concepts has been discussed with their several applications.
