A Wavelength Multiplexed Bidirectional Fiber Ring Network

Abstract

In this project, an eight-node optical fiber ring network was built that functions as a precursor to a local area network. The network uses four wavelength division multiplexed (WDM) channels and eight bidirectional add-drop multiplexers (BADM) to route analog or digital data between individual nodes. Specific wavelength channels are routed bi-directionally through the eight nodes, minimizing the number of hops a message must take to reach its destination. Information on multiple wavelengths propagates through the BADMs in both directions. Each BADM adds (drops) two wavelengths to (from) the ring network. The BADMs are constructed using thin film filters, an all-optical technology. Because the number of optical/electrical/optical conversions were reduced in this network, the benefits of optical fiber can be better utilized in small-scale networks. Showing that local area networks can operate at high data rates in a single fiber ring, while maintaining scalability and modularity, would significantly enhance the possibility of installing smaller-scale optical fiber networks.
