Abstract
-
This thesis addresses both the technical and economic performance issues of several novel local distribution fiber/coaxial CATV network architectures that are capable of supporting low-cost broadband services including analog/digital entertainment video, and at the same time meet the demand of achieving a high optical power budget, required for deeper fiber penetration. Specifically, this work proposes and analyzes several novel local distribution CATV architectures that utilize a 1.3 {dollar}\mu{dollar}m Semiconductor Optical Amplifier (SOA) based transmitter as well as a combination of fiber and coaxial cable as an upgrade to narrowband fiber-to-the-curb (FTTC) network architectures. Fiber-to-the-home (FTTC) architectures will also be investigated. The main characteristic of the proposed network architectures is the innovation of using a 1.3 {dollar}\mu{dollar}m SOA as an external modulator at the transmitter end of the proposed network architectures. This represents a major milestone in achieving the above mentioned objectives. As will be shown, in addition to performing the modulation function, the required high optical power budget can now be obtained through 1.3 {dollar}\mu{dollar}m amplification and consequently there is no need to dismantle the already deployed 1.3 {dollar}\mu{dollar}m zero-dispersion single mode fibers.;The overall objective of this work is to investigate and analyze, through computer simulation and modeling, the performance of all the critical elements necessary for the implementation of high-capacity, high-performance, cost-effective local loop distribution CATV networks based on subcarrier-multiplexed fiber communications technology. We will implement a flexible, powerful computer modeling tool for evaluating the end to end performance of the proposed local distribution CATV network architecture.;Eventually, we want to be able to model the end-to-end performance of any signal that passes through the network. This will permit us to compare and devise candidate subcarrier-multiplexed local distribution CATV network architectures and determine the appropriate field of use for each. In addition, this will enable us to determine how to use the capabilities of each architecture to best advantage and provide insight into which Subcarrier-Multiplexed local distribution CATV architecture should be stressed.
