Speed and reliable networks are the prior requirements in this emerging world. Communication is exploring in a broadway every day. Digital or Analog communication, both need the best communication medium which can help to boost up the data transfer from source to destination.  In this article, we have discussed the past, present, and future scenarios of optical communication and its evaluation in the current world. Also, we have discussed the basics of optical communication, their requirements, the development of optical fiber communication in a different field, and applications of optical fiber communication. Primarily, we cover the basic introduction of the earlier communication system compare with the optical communication system. Later on, the advantages of the optical communication system have been shared.
