Effect of Dispersion on SS-WDM Systems
(Virginia Tech, 1998-09-18)
The purpose of this thesis is to investigate the effect of dispersion on a spectrum-sliced WDM (SS-WDM) system, specifically a system employing a single-mode optical fiber. The system performance is expressed in term of ...
Measurements, analysis and modeling of the performance of direct detection receivers with an optical preamplifier
(Virginia Tech, 1993-07-16)
In the last few years, erbium-doped fiber amplifiers (EDFAs) have been investigated extensively both for their superior amplification characteristics and their applicability to future optical fiber communication systems. ...
Saddlepoint Approximation for Calculating Performance of Spectrum-Sliced WDM Systems
(Virginia Tech, 1999-07-12)
<p>Spectrum slicing is a novel technique for the implementation of wavelength-division multiplexing (WDM). While conventional WDM systems employ laser diodes operating at discrete wavelengths as carriers for the different ...
The effects of noise in CATV distribution networks with star couplers and fiber amplifiers
(Virginia Tech, 1994-09-07)
An Improved Approach to Fault Tolerant Redundant Fiber Optic Ring Design for Polled Data Networks
(Virginia Tech, 2000-02-24)
This research investigates alternate methods of implementing a redundant communications ring for polled network applications. FDDI and a unique solution (the tone method) designed specifically for this application are ...
Analysis, Design and Performance Evaluation of Optical Fiber Spectrum-Sliced WDM Systems
(Virginia Tech, 1997-06-03)
Analysis, Design and Performance Evaluation of Optical Fiber Spectrum-Sliced WDM Systems by Vivek Arya Dr. Ira Jacobs, Chairman Electrical Engineering ABSTRACT This dissertation investigates the design and performance ...
Influence of the Number of Degrees of Freedom on the Capacity of Incoherent Optical Fiber Communication Systems
(Virginia Tech, 2006-05-01)
The purpose of this dissertation is to find the channel capacity in optical fiber communication systems when incoherent detection is used with single (polarization filtering) and two-polarizations (no polarization filtering). ...
Survivability Analysis of Two Specific 16-Node, 24-Link Communication Networks
(Virginia Tech, 1998-07-15)
A highly survivable communication network is desirable, as service disruption is usually not tolerated. In this thesis we mainly investigate and discuss the survivability of two specific communication networks, termed ...
Variational Calculation of Optimum Dispersion Compensation for Nonlinear Dispersive Fibers
(Virginia Tech, 2000-05-17)
In fiber optic communication systems, the main linear phenomenon that causes optical pulse broadening is called dispersion, which limits the transmission data rate and distance. The principle nonlinear effect, called ...
Selective cancellation of interference for CDMA
(Virginia Tech, 1996-01-11)
<p>Recently, it has been shown that Multiple Access Interference (MAl) cancellation is a promising technique for improving the performance and capacity of the reverse link in a Code Division Multiple Access (CDMA) cellular ...
