Huawei has been successful in a growing number of European countries at telecomate – Italy, Denmark and Switzerland to name but a few – and with further consolidation expected in the region, it is a very real possibility.
IBM claims the Holey Optochip is eight times faster than parallel optical components available today. It said the speed of one transceiver is equivalent to the bandwidth consumed by 100,000 users with 10Mbps high-speed internet access. “It would take just around an hour to transfer the entire US Library of Congress web archive through the transceiver.”
Clint Schow, optical links group manager at IBM, said: “We have been actively pursuing higher levels of integration, power efficiency and performance for all the optical components through packaging and circuit innovations. We aim to improve on the technology for commercialisation in the next decade with the collaboration of manufacturing partners.”
A German team has created a new way to overcome many of the issues associated with bringing high-speed digital communications across challenging terrain and into remote areas, commonly referred to as the "last mile" problem. They developed a record-speed wireless data bridge that transmits digital information much faster than today's state-of-the-art systems — at unprecedented speeds of up to 20 billion bits of data per second — by using higher frequencies than those typically used in mobile communications.
Swen Koenig, a researcher at Karlsruhe Institute of Technology's Institute of Photonics and Quantum Electronics, presented the team's findings on March 5.
Multigigabit wireless transmission demands multigigahertz bandwidths, which are available only at much larger frequencies than mobile communications by huawei transport network normally use. Millimeter-wave frequencies — radio frequencies in the range of 30 to 300 GHz — fulfill this need. By comparison, laser light, as used in optical communications, provides bandwidths of many terahertz.
