Intel is giving us sneak peak into the Future by revealing the first chip that uses light aka photonics to send data. With Four lasers being used in the prototype, its able to convert light into data at about 50Gbps, something which is un-achievable using wires carrying electrical signals.
The Light Peak optical interconnect can transfer data at 10Gbits/sec in both directions, and is touted as an all-in-one replacement for USB, DisplayPort and HDMI and all others in competition. At such speeds, You can transfer a Full HD 1080p BluRay movie in a second!
Intel has demonstrated working Light Peak models twice this year, as the technology moves ever closer to launch. But today it pulled a surprise by announcing an even faster potential successor to Light Peak.
The new interface uses an indium phosphide hybrid laser inside the controller chip. By encoding data at 12.5Gbits/sec across four laser beams of differing wavelengths, the connector yields a total bandwidth of 50Gbits/sec, five times that offered by Light Peak.
“50Gbits/sec is just the beginning,” says Intel, as they plan to scale the interface up to 1Tbit/sec in the coming future.
The new interface should also be cheaper to produce than original Light Peak concept, thanks to its simple integrated design. With low-cost optics, in the future everything can be connected by fibre.
Optical data is seeing its first practical application in Light Peak, which tops out at just 10Gbps and is intended primarily to speed up peripherals in the coming 2-3 years.
