What are some techniques for fiber optic communication
Because the effect of dispersion increases with the length of the fiber, a fiber transmission system is often characterized by its bandwidth–distance product, usually expressed in units of ·km. This value is a product of bandwidth and distance because there is a trade-off between the bandwidth of the signal and the distance over which it can be carried. The process of optical communication breaks down into a few simple steps: E/O converters use light-emitting elements such as semiconductor lasers, O/E converters use light-receiving elements such as photodiodes, and optical elements such as lenses are used at the input and output. The light is a form of carrier wave that is modulated to carry information. Co pared to twisted pair and coaxial cable, it has a greater bandwidth efficiency. This essay attempts to describe recent developments in fiber-optic communication, various modulatio light pulses, is one of the rapidly.
