Fiber Optical Communication Systems, Modulation Techniques and Its Applications

Abstract

Fiber optic communication has expanded significantly in the fields of data transmission and communication engineering in the modern communication environment. Wave propagation is guided by optical fibres.it is made up of wired parts. Compared to twisted pair and coaxial cable, it has a greater bandwidth efficiency. This essay attempts to describe recent developments in fiber-optic communication, various modulation techniques used in contemporary systems, and wireless technology applications.
