Last week CNET reported that according to their source Apple is expected to introduce its Light Peak based connection technology soon.
Light Peak is an optical cable interface devised by Apple and developed by Intel to connect devices, which is significantly faster than even USB 3.0. USB 3.0 which is 10 times faster than USB 2.0 (current generation MacBooks come with USB 2.0 ports) can manage a theoretically maximum throughput of 4.8Gbps while Light Peak can manage 10Gbps in both directions simultaneously.
