IBM researchers have unveiled a prototype technology which could offer transmission of data at up to eight terabits per second -- equivalent to around 5,000 high definition video streams -- with just 100 watts of power consumption.
Such a system, if it can be commercialised and brought in at a reasonable cost, could be used for bringing ubiquitous high definition content.
As high definition video becomes more widespread, this technology may enable widespread HD video sharing and video on-demand by dramatically increasing the bandwidth of video servers. Web serving sites that host videos could use the technology to access libraries with millions of high-definition movies and video clips in seconds, speeding up access for users. By incorporating an optical data port in laptops, HD video recorders, personal mp3 and video players, cell phones, or PDAs, HD video content could be stored and displayed on high- resolution external screens.
The optically-enabled circuit boards, or "Optocards" employ an array of low-loss polymer optical waveguides to conduct light between transmitters and receivers. The complete databus constructed with these Optocards not only incorporates a large number of high-speed channels, but also closely packs them to achieve unprecedented density: each waveguide channel is smaller in size than a human hair. The packaging approach for the complete system is unique in that it utilises hybrid chip integration to produce a highly integrated optical module, or "Optochip"
