Has achieved a milestone in data transfer speed. This can truly be dubbed as 'enter the network of future!'
n cooperation with Micram, the Fraunhofer Institute for Telecommunications (Heinrich-Hertz-Institut) and Eindhoven Technical University, Siemens has successfully tested the network of the future.
Recently and for the first time made public, Siemens researchers have successfully tested transmission at 107 Gbits per second with 100 per cent electrical processing in the transmitter and receiver, the first time this has ever been achieved outside the laboratory. On a 100 mile test route in the US, they have succeeded in bettering the current maximum transmission performance per channel by a factor of 2.5.
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 worldâ€™s largest optical network operators, in which Siemens has previously deployed a 40 Gbits per second optical network for commercial use.
This record performance is made possible by a newly developed transmission and receiving system which can process data directly before and after its conversion into optical signals using electrical processing only. On the high-speed routes of the Internet, data is transported in the form of light signals.
Until now, for very high data rates, signals had to be split into multiple lower data rate signals and later be reconverted from optical to electrical in order to avoid data bottlenecks in the downstream electronics. This adds cost and reduces system capacity.
A few months ago, Siemens researchers proved the feasibility of a receiver with 100 per cent 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 per cent 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.
