A research team, headed by Xiang Zhang, a UC Berkeley engineering professor, has built an ultra-small optical device that can control the switching on and off of light pulses using Graphene. This extraordinary device is guaranteed to revolutionise communication, both in terms of speed and how we do it, in the very near future.

Two independent groups have developed a fiber optic cable capable to transferring data at an incredible rate of 100 Terabits per second. This unbelievable speed is far greater than anything available today.
