Abstract:

The ever-increasing demand for broadband services by end-user devices utilising 3G/4G/LTE and the projected 5G in the last mile will require sustaining broadband supply from fibre-linked terminals. The eventual outcome of the high demand for broadband is strained optical and electronic devices. The backbone optical fibre transport systems and techniques such as dense wavelength division multiplexing (DWDM), higher modulation formats, coherent detection and signal amplification have increased both fibre capacity and spectrum efficiency. A major challenge to fibre capacity and spectrum efficienc

Abstract:

A class of low nonlinearity dispersion-shifted and dispersion-flattened fibers for broadband and long haul applications is presented. The refractive index profiles of these fibers assume a depressed-core multi-clad geometry in order to achieve effective-areas much larger than those in conventional optical fibers. A systematic approach for designing large effective-area dispersion-shifted fibers, using a reference W-index profile to initiate the design, is presented. Transmission properties, including effective-area, mode-field-diameter, dispersion, dispersion slope, cutoff wavelength, and bend

Abstract:

The primary aim of the thesis is to determine the spectrum efficiency and power penalty of multi-level Subcarrier Multiplexing (SCM) transmission. To perform quantitative analysis, this thesis first develops a fiber transmission model. When there is one SCM transmission channel, it is found that the power penalty due to multi-level is 5 dB per bit at the same bit error rate (BER). For multiple channel SCM transmission, to reduce adjacent channel interference (ACI), it is found that binary transmission has the best spectrum efficiency for Non-Return-to-Zero (NRZ) pulses at the same BER.

Abstract:

Many erbium doped fiber amplifier (EDFA) based multi-wavelength optical networks employ techniques such as burst-switching or packet switching where the time interval between traffic blocks can be long enough to induce EDFA optical power transients. The optical power transients are created by abrupt changes in the average input power to the EDFAs and can adversely affect the performance of the network. To mitigate the effects of EDFA optical power transients on optical networks, a method called power shaping where heads and tails are joined to the beginning and end of a traffic block is invest

Abstract:

With ever-increasing networking bandwidth demand imposed by data explosion in recent years, optical source generation plays a more and more important role in fiber optical communications. Today wavelength-division-multiplexing (WDM) which refers to encoding independent information onto different wavelengths becomes a widely used technique to increase the transmission bandwidth. However, current WDM system usually requires one single laser source for each distinct wavelength channel which is relatively expensive and cumbersome. Moreover, current WDM system is usually confined to conventional ba

The focus of this thesis is the computation of bit error rate in an optical fiber communication system when an avalanche photodiode (APD) is used for detection. The use of the APD increases the complexity of the BER calculation because it introduces an additional noise phenomenon: shot noise (plus multiplication noise). There are several methods to compute the BER. This thesis considers three of these methods: the Gaussian approximation, the saddlepoint approximation and a numerical quadrature method. An in-depth analysis of each computation method is presented after a thorough study of APD ch

How to communicate ?Human beings use the voice or gestures to give shape to their ideas. In digital communications, a modulation scheme is used to give shape to bits of information, i.e. to convert zeros and ones into an analog waveform. The question of an ideal modulation scheme is discussed in this thesis and we study the one that seems the most promising to us. The orthogonal frequency division multiplexing (OFDM) modulation is the most popular multicarrier modulation scheme nowadays. The main advantage of OFDM is its simplicity.

The demand for faster data transmission is ever increasing. Wavelength division multiplexing (WDM) presents as a viable solution to increase the data transmission rate significantly. WDM systems are based on the ability to transmit multiple wavelengths simultaneously down the fibre. Unlike time division multiplexing (TDM) systems, WDM systems do not increase the data transfer by increasing the transmission rate of a single channel. In WDM systems the data rate per channel remains the same, only multiple channels carry data across the link. Dense wavelength division multiplexing (DWDM) promises
