Siemens Achieve Transmission Rates Of 107 Gbits/S !!!

In cooperation with Micram, the Fraunhofer Institute for Telecommunications and Eindhoven Technical University, Siemens has successfully tested the network of the future. This involved the 100% electrical processing of data rates of 107 Gbits per second and transmission over a 100 mile long fiber-optic route in the U.S. – the first time this has ever been done outside the laboratory. The record performance was made possible by a newly developed transmission and receiving system that processes the data by purely electrical means directly before and after its conversion into optical signals. The test was conducted at a long-haul network at one of world’s largest optical network operators, in which Siemens has previously deployed a 40 Gbits per second optical network for commercial use.

Ultra-high bandwidth capacity in core network will be required to cater the traffic generated by online games, music, and video downloads. By 2011, legal music downloads alone will account for 36 percent of the entire music business in Europe according to market research institute Forrester Research. And network operators are reacting to this development: They’re not only expanding their access networks with broadband technology, but are also having to adapt the capacities of their optical core networks accordingly. To prepare for the data traffic volume of the future, Siemens is already working to develop key technologies within its labs.

A few months ago, Siemens researchers already proved the feasibility of a receiver with 100% electrical processing for optical transmission at 107 Gbits per second in which the signal from the photo diode is picked up and processed directly by a chip. Now the next step has been taken and the optical transmitter has been “fully electrified.” Siemens has thus developed a system that processes data 100% electrically directly before and after conversion from electrical into optical signals, and vice versa. The system can handle data volumes of 107 Gbits per second, which is currently a record. 107 Gbits is approximately equivalent to the amount of data that fits on two DVDs today.

Intel Launches Intel Next-Gen Wireless-N!

Intel introduced the Intel Next-Gen Wireless-N network connection, an upgrade to the wireless component found inside Intel Centrino Duo mobile technology and other Intel-based laptops that helps consumers better connect to wireless networks.
As notebook PCs increasingly download broadband-intense content such as movies, videos and music, a more powerful networking solution is needed. Based on the draft 802.11n Wi-Fi specification, the Intel Next-Gen Wireless-N technology addresses that need by offering users up to five times(b) the performance and twice the wireless range – while providing up to an extra hour of notebook battery life when compared to existing Draft-N products. The new wireless-N technology improves the home network experience – especially when multiple people access their wireless network simultaneously and enjoy bandwidth consuming applications such as audio and video entertainment. Intel’s Next-Gen Wireless-N product reduces “dead spots” in the home; optimizes high-definition (HD) entertainment experiences such as streaming HD movies; improves battery life and provides the benefit of working with existing 802.11 a/b/g access points.
