The full form of RoF is Radio over Frequency technology. Present generation is the era of the network. Thus, the entire information interchanges over the network and the data traffic may occur on the network due to excessive data being transferred. Radio over Frequency is a technique that offers access to the bandwidth of channel. Hence, it is utilized to regulate traffic over the network in the condition of wireless networks. In this paper, mainly attention on communication channels such as ophthalmic wireless communication (OWC) and free space optics (FSO). Multiple encoding formats such as NRZ, CS-RZ, DRZ, and MDRZ are also discussed in this paper to transmit information along with modulation signals

With the advancement in the technology, the needs of the users are also growing. The demand for higher bandwidth is one of these requirements. In order to fulfill this, Fiber Optic communication is developed. It transfers the data in the form of light waves and also achieves higher data transmission rate by facilitating the wider bandwidth for transmission. This mode of communication uses various encoding schemes such as NRZ and various communication channels to improve the quality of communication.The implementation is done by using optisystem. The various encoding schemes are implemented with three different communication channels. It is observed that MDRZ outnumber rest of the encoding scheme with respect to the value of BER and Q. Factor.
