In the feature(next 4 years) we will transfer data up to 50Gbps, far more than actual Thunderbolt technology use.
The new technology will allow the transfer of a HD movie in one second, Intel research program in photonics started several years ago, when the company started to replace the transfers of data that was made using electrons.
The new type of connection requires the existence of a silicon chip transmitter and receiver, each integrating previous Intel proprietary technologies, such as hybrid silicon laser, high-speed optical modulators and photodetectors.
