Intel demos 50 Gbps optical link

Intel has announced the development of an integrated, end-to-end, silicon-based optical system that can sustain a speed of 50Gbps.

A transmitter chip uses four hybrid silicon lasers running at 12.5Gbps each and operating at different wavelengths, modulates them into data-carrying pulses, then multiplexes those pulses into a single stream of light that it beams through an optical-fiber cable.

At the other end of that cable, a receiver chip demuliplexes the photon stream, distributes it to four germanium-silicon photoreceptors, which convert the pulses to electrical digital signals and sends that data further on its way.
