An optical fiber is an important communication channel as it proposes a high bandwidth and less attenuation, and can be easy challenging assistances such as huge-quality data transmission and others in computer networks. The basic optical transmission system consists of three basic elements which are fiber media (transmission channel), light sources as the input (covert electric signal into optic signal) and light detector as the output (convert optic signal into electric signal). FBG is the key component in optical communication system as, dispersion compensators, filters and flatteners gain. There is need to introduce mechanism that should be capable to provide data security in less time. More over there is need to introduce energy efficient mechanism that should be capable to reduce the size of packet during data transmission. There are several problems that are faced due to attenuation in fiber optics. There is need of repeater in order to regenerate the signals. Process working principle of proposed technique that is being used enhancement of security in steganography has been discussed with process flow and result. It states how brute force and timing attack are not applicable on proposed technique.
