Japan in reach of terabit per second optical transfer speeds.
Wireless Method Helps Optical Communications Break Speed Barrier
TOKYO (Nikkei)--A research team at Tohoku University has developed a way to boost optical communications beyond the technical speed barrier by exploiting a data-transmission method normally used for cellular phones and other wireless means of communication.
The university team has solved the stability problem using a special laser that makes it feasible to pipe data down a glass fibre using the QAM method at blistering speeds. Although we shouldn't expect to be choosing from internet connections rated in Tbit/s anytime soon, the development could one day make us look back on ADSL as fondly as we now do our 56K modems.
