A study of optical modulation and higher transmission capacity

Abstract

In this paper the assessment of different approaches to overcome the capacity shortage in optical fiber communication. Optical transmitters, receivers and media are not preferred owing of high cost, unavailability of complex hardware setups and economic infeasibility of upgrading media. Consequently, Optical modulation is the sole and promising technique with cost effectiveness in the current scenario. By incorporating certain modulation scheme in optical transmitter and receiver only data-to-be-sent is required to modulate before sending. It will help to cater this capacity crisis quite effectively.
