Vendors demo interoperability of 100G optical interfaces

Fujitsu Ltd., NEC Corp., and Anritsu Corp. say they have successfully demonstrated the interoperability of 100G interfaces that comply with the Optical Transport Network (OTN) standard for transmitting 100-Gigabit Ethernet signals over an optical network. The trio claims this is the first time that 100G equipment from different vendors have been shown to interoperate over multiple networks.

Details of the test are being presented at Japan's biggest conference on optical communications, the 25th Symposium on Optical Communication Systems, running December 15–16, 2011, in Mishima, Shizuoka Prefecture in Japan.

For the demonstration, Fujitsu provided its FLASHWAVE 9500 DWDM transmission system equipped with OTN interface technology, and NEC supplied its SpectralWave DW7000 Series non-blocking optical transport and cross-connect system with the OTN interface technology.

Anritsu provided its MD1260A 100G analyzer as test instrumentation for the 100-Gbps Ethernet interfaces used in the tests.

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 (chaired by Naoki Yamanaka of Keio University) of the Kei-hanna Info-Communication Open Laboratory. The Open Laboratory provides an open and neutral R&D environment for conducting tests among multiple vendors.
