Alliance enables transmission of 100Gb/s Ethernet signals over multiple optical networks

1 min read

Fujitsu, NEC and Anritsu have successfully demonstrated interoperability testing for optical network interface technology allowing telecommunications carriers to connect to each other at 100Gb class speeds – a world first.

According to the companies, this is around 2.5 to 10 times faster than current speeds and the first time that the transmission of 100Gb/s Ethernet signals over multiple optical networks using equipment from multiple vendors has been successfully demonstrated. All three companies participated in the joint effort to develop an interface that compiled with Optical Transport Network (OTN) technology for transmitting 100Gb/s Ethernet signals over an optical network, standardised by the International Telecommunication Union-Telecommunication Sector (ITU-T) in 2010. Fujitsu and NEC performed an assessment of interoperability and a basic performance assessment of an OTN interface that accommodates 100Gb/s Ethernet, on prototype equipment from multiple vendors, using instrumentation provided by Anritsu. The tests were the world's first to successfully demonstrate the interoperability of equipment using this interface. The tests were carried out as part of the 'Ethernet over OTN Technology R&D Project', one of the joint research topics for collaboration among industry, academia and government being pursued by the Interoperability Working Group of the Kei-hanna Info-Communication Open Laboratory. Details of the field tests will be presented from 15 to 16 December at the 25th Symposium on Optical Communication Systems, Japan.
