Abstract
-
The thesis is a complete component and system level analysis and feasibility study of self-healing local exchange ring networks based on wavelength division multiplexing (WDM) technology. Two type WDM ring have been studied: two-fiber uni-directional path-switched and line-switched ring, four-fiber bi-directional line-switched ring. The scalability, survivability of the WDM optical high-capacity ring networks have been investigated, analyzed and optimized through the computer simulation and modeling. The optimization of critical elements necessary for the implementation of such a optical ring network have been fully investigated. A 21-node uni-directional path switched self-healing ring with an aggregate capacity of 210 Gbit/s (assuming 10 G/s SONET ADMs are used) has been designed without using any external device to balance the gain flatness. An 11-node full mesh connection bi-directional line switched self-healing ring with an aggregate capacity of 825 Gbit/s has also been designed and assessed. The signals quality has also been assessed in each node for either drop and pass according to the unique wavelength assignment. The average signal to noise ratio of better than 25 dB with a gain variation less than 5 dB have been achieved without using any external gain variation devices.
