German equipment vendor ADVA Optical Networking has snagged a high-profile customer for its proprietary 100G metro optical system in the shape of the Amsterdam Internet Exchange (AMS-IX), one of the largest internet exchanges in the world.
This is the first publically announced customer for ADVA’s metro 100G system.  The 100G system is based on a direct-detection scheme using four 28Gbps channels in a single ITU grid assignment, and offers a cost-effective solution for 100Gbps data transport across distances of up to 500km, the company claims (see ADVA's 100 Gigabit card targets the metro).

AMS-IX will deploy ADVA’s FSP 3000 platform as part of its new core network infrastructure connecting data centers throughout Amsterdam. Available as a line card for the FSP 3000, the 100G capability will double AMS-IX's current network capacity in order to meet growing bandwidth demands.
AMS-IX says it worked closely with ADVA to test the 100G system thoroughly both at ADVA’s facility in Meiningen, Germany, and again on a live testbed. At the end of this process, the organisation was persuaded that the system would meet its need for a high-capacity system operating in a metro environment.

"We are experiencing exponential growth in data transported over the exchange platform," said Henk Steenman, CTO at AMS-IX. "We expect that this growth will continue in the next three years. To accommodate this development we are expanding and upgrading the core of our network. Upgrades will be based on new 100G technology and ADVA Optical Networking provides us with a 100G optical network solution to be used in the Amsterdam metro area."
Other vendors are developing 100G direct-detection schemes for the metro, but the market is still in its infancy (see Metro 100G direct detection gains momentum).
