A Wavelength Multiplexed Bidirectional Fiber Ring Network

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