Register Hardware reports: [edited]
Intel has announced the development of an integrated, end-to-end, silicon-based optical system that it says may drive down the cost of high-speed, error-free interconnects to under a dollar per port.
The prototype "concept vehicle" that Intel unveiled Tuesday is essentially a two-chip system that can optically transmit and receive data at 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 on its way.
