The promise of 400G to meet growing customer demand

DE-CIX has been rapidly expanding to new locations and seeing traffic grow by as much as about 30% per year at its exchanges. During the 2020 pandemic lockdowns, traffic suddenly increased at an even faster rate. This growing customer demand prompted the internet exchange provider to take a serious look at 400G.
DE-CIX CTO Dr. Thomas King explains why 400G is the key to staying ahead of traffic growth and customer expectations: “Our largest customers are already asking for 400G, and we see massive growth potential in this area. This technology is extremely exciting on many levels, allowing us to create an entirely new experience for customers with simpler and faster service provisioning. We needed to be able to turn up additional capacity quickly and efficiently and we knew 400G was the answer.”

Easy-to-use open line systems from Smartoptics deliver 400G

When a new potentially game-changing technology like 400G comes along, DE-CIX conducts an extensive vendor review. In this case, the Internet Exchange provider was looking for a DWDM vendor with excellent stability and quality to match DE-CIX’s own high standards for services provided to its customers.
“As a long-standing key advocate for open line systems and a recent 400G pioneer, Smartoptics emerged as the clear-cut winner, who met our requirements best. One of the greatest differentiators is that Smartoptics products are so easy to use – it’s basically plug and play. This won them extra points in our selection process, and we were, and remain to this day, confident that we made the right choice,” Dr. King explains.

A fully redundant, cost-effective and future-proof network architecture

DE-CIX evaluated the two paths available for 400G network architectures: ROADM and point to point (P2P), both supported by Smartoptics. DE-CIX opted to go the P2P route, directly connecting all core and edge routers in the four core hubs of its backbone network. This fully meshed router setup enables them to ensure full redundancy and maximum capacity.

Since this new type of network for 400G – based on the Smartoptics open line system – requires fewer infrastructure components that are essentially plug and play, it will allow DE-CIX to simplify both its network architecture and operations. This results in cost savings on both the CAPEX and OPEX side. Initially, the Smartoptics open line systems were implemented on DE-CIX’s Frankfurt backbone network to provide 400G, with other locations to follow.

“The massive implementation project in Frankfurt is progressing very smoothly. We’re really impressed with how well it works so far, and we appreciate how future-proof the solution is. Smartoptics is highly professional, agile, and quick to respond to our needs. We look forward to continuing to work with them far into the future as we roll out high-speed DWDM to more locations,” says Dr. King.
