Awareness of mobile apps and other wired and wireless devices are leading to more and more bandwidth hungry applications with an increasing demand for broadband services which are putting pressure on communication systems to increase their capacity. To attain such systems one must have increased feeder network capacity which can operate at higher carrier frequencies and make a benchmark with increased user population densities. Hence, optical communication system for long-haul channel transmission has become an integral part of today¿s society. Meanwhile, raising the carrier frequency and thus reducing the radio cell size leads to costly radio system while the installation and maintenance costs related to higher bandwidth silica fiber render its effect and hence making it impractical for in-home and office environment. OFDM is a challenging term to all constraints in optical system which has been proven as an outstanding and promising technique both for short distance as well as long-haul transmission at very high data rate.
