With a commitment to technology that supports the rapid growth of new applications and services in the international NREN community, Europe-based research and education network SURFnet recently demonstrated 100G dense wavelength-division multiplexing (DWDM) solution between Amsterdam and Geneva.
SURFnet completed a technology test of Cisco's 100G DWDM solution between the National Supercomputing Center, SARA, in Amsterdam, the Netherlands, and CERN in Geneva, Switzerland, using the Cisco (News - Alert) ONS 15454 M6 Multiservice Transport Platform.
An error-free transmission of a 100G alien wavelength using Cisco single carrier coherent optical technology was observed between Amsterdam and Geneva across SURFnet's existing 1650km optical DWDM system. The Cisco 100G coherent DWDM solution used during the testing allowed for re-utilization of SURFnet’s existing fiber infrastructure without any disruption while enabling new 100G data services.
According to Cisco, this evaluation demonstrates the ability of the company to offer 100 Gigabit technologies, which meet the requirements of the Next Generation Internet for core, edge, data center, and transport.
As a research and education network, SURFnet facilitates collaboration between researchers, teachers, and students in the Netherlands using information and computing technology. Together with partners, it offers high speed communication services between leading innovation centers and universities in Europe and throughout the world.
According to a press release, the test involved introducing 100G single carrier optical interfaces into SURFnet's existing optical infrastructure made up of a combination of 10G, 40G, and 100G wavelengths. The 100G DWDM solution by Cisco was operational in a short duration without any disruption to the existing network.
The test indicates that SURFnet can leverage its current infrastructure and help protect its network investment while supporting new 100G data services over the existing fiber infrastructure. Precisely, the 100G technology enables SURFnet to use its existing 50GHz spectrum band more efficiently and provide cost-effective all-optical connectivity across international borders.
The Cisco ONS 15454 M6 platform, which was used for the testing, can support 42 x 100G wavelengths in a single bay.
Roeland Nuijts, optical network architect, SURFnet, said in a statement, “This 100G alien wavelength demonstration is another important step in the future of international networking across geographical, technical and administrative borders. Being able to use high-bandwidth wavelengths over open transmission systems from different equipment vendors supports new approaches to networking. The use of all-optical alien wavelength 100G technology is what will enable cost-effective international research networking.”
