Nokia Siemens Networks 
announced the transmission of 100 Gbps line rate over a record 4,000 km span of undersea cable. The trial of the Submarine Line Terminal Equipment (SLTE) solution was performed over a submarine segment between Florida and Puerto Rico for a major submarine cable network. As part of the demonstration, Nokia Siemens Networks also achieved 40G DWDM transmission over a distance of 9,000 km.
Nokia Siemens Networks’ SLTE solution based on its hiT 7300 platform increases the capacity of the already deployed undersea cable links by adding 40G and 100G DWDM channel and bandwidth management capabilities to support current and future network requirements. Nokia Siemens Networks’ SLTE solution with new transmission capacities of 40G and 100G will be commercially available this year.
“Our global customers are faced with a continuous need to expand their installed network capacity to keep up with the tremendous increase in traffic requirements,” said Pathmal Gunawardana, head of Transport Networks business unit, North America, Nokia Siemens Networks. “As we support them in terrestrial network expansions, it made perfect sense to do the same for their global networks as well, which often include submarine cable links. While terrestrial networks increase capacity, these submarine cable links often remain a bottleneck.”http://www.nsn.com
