Bahnhof, one of Sweden’s oldest and largest internet service providers, has chosen ADVA Optical Networking to overhaul its national backbone network in response to rapid growth in bandwidth demand from its enterprise and residential customers.
Using equipment and expertise from ADVA, the operator has implemented a meshed DWDM network, complete with multi-degree reconfigurable optical add-drop multiplexers (ROADMs), which link every city in the south of Sweden from Stockholm to Malmo. The long-haul network, which incorporates the Danish capital, Copenhagen, and Norway’s capital, Oslo, transmits capacity of 100Gb/s at every point.
‘Our customers put a lot of trust in us to provide reliable, secure services,’ said Gustav Bergquist, CTO, Bahnhof. ‘Now, in order to provide more homes and businesses with ultra-fast connectivity and offer 100Gb/s at fixed, attractive prices, we’re putting our trust in ADVA Optical Networking. Their team is supporting us at every stage from design to demos to deployment. They understand what’s important to us and to our customers.’
Commenting on the technical solution, he said: ‘Deploying the ADVA FSP 3000 with ROADM technology in our new national backbone will enable us to bring phenomenally high bandwidth to even more enterprises and deliver world-class triple-play services to more homes. Future-proofing is also vital so we’re investing in a solution that can scale alongside rising demand and the growth of the internet of things.’
The new 100Gb/s network features 48 nodes connected in a ring topology. Multi-degree ROADMs are deployed at 36 drop sites, creating remote cross-connections on the optical layer to boost availability and simplify operations. The freedom to add and drop traffic without deploying personnel enables Bahnhof to greatly improve service and operational agility.
The ADVA FSP 3000 supports 96 100Gb/s coherent optical channels and has a total capacity of 9.6Tb/s. Using muxponder cards, Bahnhof will be able to offer 10Gb/s or 100Gb/s connectivity to customers anywhere on its network. What’s more, the modular architecture of the ADVA FSP 3000 makes Bahnhof’s new infrastructure fully scalable for future growth and ready for the deployment of encryption at the optical network layer.
