::Intel Silicon Photonics.....50 Gbps Transfer Speeds.

Using copper cables to transfer data around a computer? Get your head out of the sand, Old timer! Intel thinks that's on the outs and is touting its recent accomplishments with Silicon Photonics and integrated lasers, using light pulses to move data at 50Gbps (last time we heard Intel tout the tech was when it hit 40Gbps speeds in 2007). The emphasis is on low-cost, high-speed fiber optics, the removal of cable clutter, and with the speed boost, the ability to try new system designs by being able to space chips and components farther apart from one another without as much hit on speed -- all theoretical at this point, of course. Researchers hopes to hit terabit per second speeds further down the line. 
Lets just wait and see this technology hit homes.
