Siemens Sets New Network Speed Record

Germany's Siemens AG has set a new speed record for electrical
processing of data through a fiber-optic cable, it said on Wednesday,
opening the possibility of cheaper Internet and data networks.

Siemens said in a statement it had processed data using exclusively
electrical means at 107 gigabits per second -- roughly two full DVDs
per second -- and sent it over a single optical fiber channel in a 100
mile-long (161-kilometre) U.S. network, the first time outside of a

Online games, music and video downloads are generating increasing
amounts of Internet traffic, creating a need for ever faster and
affordable transmission.

The test, 2.5 times faster than a previous maximum transmission
performance per channel, was done in cooperation with Germany's Micram
Microelectronic, the Fraunhofer Institute for Telecommunications and
Eindhoven Technical University of the Netherlands.

Siemens said the advantage of its method of using electrical
processing only was that it removed the need to split signals into
multiple, lower data-rate signals to avoid bottlenecks -- which makes
transmission slower and more expensive.

"Such a system would be particularly interesting for the future
100-gigabit Ethernet on which the telecommunication providers are
currently working," Siemens said.

Ethernet networking technology powers the vast majority of local
computer networks, such as corporate networks, but is increasingly
important for larger networks, due to its flexibility, as the
technology becomes cheaper.

Siemens said it expected the first products based on the prototype
could be on the market within a few years.
