Jaapani tehnohiiud Fujitsu, NEC ja Anritsu demonstreerisid 100Gbit/s ühendust tavaliste optiliste sideliinide kaudu, kasutades erinevate tootjate seadmeid, mis väidetavalt on maailma esimene selletaoline edukas test. Telekomide omavaheliseks ühendamiseks mõeldud 100 Gigabit ühendus oleks senistest 2,5 kuni 10 korda kiirem.

Tokyo and Atsugi, Japan, December 13, 2011 — Fujitsu Limited(1), NEC Corporation(2), and Anritsu Corporation(3) today jointly announced that, in field tests, for the first time in the world they successfully demonstrated interoperability testing for optical network interface technology allowing telecommunications carriers to connect to each other at 100 Gigabit-class speeds, some 2.5- to 10-times faster than current speeds. Accordingly, this is the first time in the world that the transmission of 100 Gbps Ethernet signals over multiple optical networks using equipment from multiple vendors has been successfully demonstrated.
Demonstration Overview and Results
Fujitsu, NEC, and Anritsu participated in the effort to develop an interface that complied with Optical Transport Network (OTN)(5) technology for transmitting 100-Gbps Ethernet signals over an optical network, standardized by the ITU-T(6) in 2010. Fujitsu and NEC performed an assessment of interoperability and a basic performance assessment of an OTN interface that accommodates 100-Gbps Ethernet, on prototype equipment from multiple vendors, using instrumentation provided by Anritsu. These tests were the world's first to successfully demonstrate the interoperability of equipment using this interface, and they confirmed that 100-Gbps Ethernet signals were transmitted with 100% transmission efficiency. This interface technology will enable the optical networks of different telecommunications carriers to be interoperable at 100 Gigabit-class speeds, 2.5- to 10-times as fast as current speed levels.
These 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 (chaired by Naoki Yamanaka of Keio University)(7) of the Kei-hanna Info-Communication Open Laboratory. This is the first time that multiple vendors have demonstrated such results using an open and neutral R&D environment as provided by the Open Laboratory. |
