Nokia Siemens Networks has conducted laboratory tests that successfully transmits data at speeds 200Gigabit per second (200g) through a standard optical fiber. The success of this trial marks an important step towards network 400g.
The test was conducted following the recent announcement of Nokia Siemens Networks on equipment Dense Wavelength Division Multiplexing (DWDM) is ready to support speeds of up to 400g. It is estimated, the network operator will be able to hold the optical network is ready to 400g in 2011.
"Our latest test shows that this time it is possible to reuse the existing optical fiber network and double the speed of up to 200g per wavelength," said Oliver Jahreis, Head of Product Management for WDM Networks, Nokia Siemens Networks, in his statement, October 4, 2010 .
This development, said Jahreis, an important milestone and shows that we are on the right track towards a cost-effective approach to network 400g and so on.
Jahreis mention, when demand for high capacity transport network continues to increase, network operators need to increase its speed per wavelength in their existing networks. "This will help the operators get the most from their investment, because it adds additional fiber optic lines to meet capacity requirements is an expensive option," he said.
The move to 400g is the next step in the deployment of optical transport, following 10/40/100G network today.
"The use of existing optical fiber back to the evolution towards a higher network capacity will protect the investments of the operators, and provide higher data speeds to end users," said Jahreis.
Nokia Siemens Networks is conducting this trial at the research and development center in Munich using prototype equipment developed.
