[b]Intel[/b]'s Components Research Lab is working on ways to replace copper wiring between motherboards and chips inside computers with faster, more energy-efficient optical fibre.

[blockquote]The lab has created a prototype system with chips connected to each other through eight optical channels transferring data at more than 1 gigabit of data per second for an aggregate bandwidth of over 8Gbps (gigabits per second). The individual channels, called waveguides, can transfer data at up to 3Gbps.
