Infinera: Super-Channels DWDM Transmission Beyond 100Gb/s

A number of different industry surveys indicate that total internet demand is growing at about 40% per year. This growth is driven mainly by increasing video traffic in the network and by mobile access, with video clients shipping on an all smart phones and tablets, enabling video to be consumed more conveniently via network connections anywhere, anytime. Service providers are faced with compounded growth in demand for network capacity. Technological advances to date have allowed an increase in DWDM data rates to 100 Gb/s per optical carrier, but these technologies will soon be close to their practical or theoretical limits. This whitepaper looks at how super-channels offer a practical and timely solution to the problems of scaling operational processes, optimizing fiber capacity and reach, and supporting the next generation of client services beyond 100G.
