IEEE researchers have found [PDF] that core networking usage is currently doubling every 18 months on an average and because of this they are estimating that the bandwidth availability has to be increased by 100-fold every 10 years. With such figures there are two different groups within the IEEE camp; one advocating speeds of up to 400Gbps while the other looking to go for 1Tbps.
When it comes to providing such high speed connectivity, technical requirements become the prime focus area. Trying to achieve 1Tbps or even 400Gbps transfer speeds would invariable involve cabling; either copper or fiber. When it comes to copper cables, 80 copper cables may be required to put together a dual-channel 1Tbps connection and this definitely won’t be pretty. Considering the cost, well it is definitely going to be high as well. Fiber is definitely going to be an obvious choice. But, there is no definitive data yet for the new Ethernet standard.
“…aggregating 25-gigabit connections into a group of 16 would get to 400Gbps, and 40 would get to 1Tbps. Doubling that so data could travel in both directions at that speed would mean 80 connections, and that would be “not pretty,” notes C|NET with an understatement from D’Ambrosia, chair of new Higher-Speed Ethernet Consensus group.
