[Name of the Institute]Abstract

This thesis deals with the limiting factors in the design of a long-haul fiber-optic communication system, and the techniques used to suppress their resulting impairments. These limiting factors include both linear and nonlinear effects, such as fiber chromatic dispersion and the Kerr nonlinearity, and the modulator-induced nonlinearity. In the next chapters, the conditional probability density function (PDF) of the received electrical signal given transmitted bit '1'/,0' for a coherent fiber-optic transmission system based on binary phase shift keying (BPSK) is mathematically derived. Both amplified spontaneous emission (ASE) noise and fiber nonlinearity are taken into account. The results show that the conditional PDF of given bit '1' or '0' is asymmetric when intra channel four-wave mixing (IFWM) is dominant, while it becomes nearly symmetric when the variance of ASE is much larger than that due to IFWM. The standard deviation of the received signal is calculated analytically. The system parameters, including optimum dispersion map and pre-compensation ratio, are optimized by analytically calculating variance of IFWM. Significant computation efforts can be saved using this approach as compared to full numerical simulations of the nonlinear Schrodinger equation, without losing much accuracy.

Parallel Fibers in between receiver and transmitter

Introduction

Technology and communication are now interlinked with each other up to a huge extent. In fact, it will be fair to say that various scientists, researchers and research institutes have dedicated their time in order to propose, plan and implement various technological wonders and gadgets in order to achieve effective communication means and methods. It has been long since scientist and other experts in the communication field have been working on finding ways to ensure accurate and erroneous data and information transmission in order to achieve effective communication between two devices or ultimately the human operators operating those devices. Hence, after years of research, many such tools and ways were proposed, researched and implemented by the scientists. Out of many, the use and applications of fiber in the fields of communication is a common practice. Therefore, fibers in various forms through different methods are used to ensure non-erroneous data transmission and ultimately achieving affective communication.

Literature Review

Fiber Optics are undoubtedly the most recognized means of communication in various devices. Originated first in the year 1970s, the use of fiber or fiber optics has rejuvenated the industry of telecommunication and all the related aspects. Moreover, they have also played an important role in the advent, development and progress of Information age. In fact, because of the unlimited advantages that it has to offer, optic fiber communication has overshadowed the use and application of copper wire networks in all the core networks.

Therefore, all researchers, scientists and other professionals have diverted their attention to this particular field of communication. Hence, many researches since have been put forth a number of ideas and theories in relevance to the topic. These researches so far have discussed the characteristics of the fiber optics, their uses and applications in several fields and ...
