This book offers an insight into data centre transport technology centres and the principal techniques for modern communication transmission of ultra-wideband channels. Beginning with an introduction to digital transmission technologies and data centre networking, the text progresses to discussions on access and DC networking transmission technologies and super-channel transmission by multi-carrier sources, before concluding with a chapter on photonic signal processors. This comprehensive and up-to-date overview is an invaluable source for scientists, engineers, professors and mid-senior level students involved with data transmission and processing.
