We propose an optimization model minimizing number of wavelengths in passive optical backbone networks and obtaining the same resource usage as in networks based on active switching while reducing both cost and power consumption.
By utilizing advanced optical coherent transmission and electrical compensation technologies, two novel passive wide area network (WAN) solutions, filterless and semi-filterless optical networks, are able to eliminate the usage of the expensive active photonic reconfigurable components by interconnecting the nodes with passive optical power splitters/combiners and using tunable transceivers. Therefore,...
Advances in optical coherent transmission and electrical compensation technologies (such as coherent receiver and forward error correction FEC) have stimulated ideas for novel optical network architectures. Recently proposed passive wide area network solution, referred to as filterless optical network [1–2] eliminates or minimizes the usage of active photonic reconfigurable network elements. In this...
