Transmission at 40 Gbit/s requires taming tough technical problems

Market analysts forecasted that 40-Gbit/s transmission was the next disruptive fiberoptic technology. Few engineers think 40 Gbit/s is impossible, but higher speed may not be achieved easily or cheaply, and when and if it will become the alternative to adding more channels at 10 Gbit/s remains to be seen.
