Arelion Completes Multi-vendor, Multi-layer Field Trial

Arelion (formerly Telia Carrier) announced it has taken the next step in converging its IP and optical networking layers through a series of trials conducted with Acacia and Cisco over multiple, third-party, open-line systems. On a live fiber route with existing ROADM infrastructure between Hamburg and Copenhagen, Arelion leveraged Acacia Bright 400ZR+ QSFP-DD coherent modules with greater than +1 dBm transmit power between Cisco 8000 and NCS 5700 router platforms. The trial demonstrated the seamless integration of routed optical networking with DWDM transponders carrying wavelength services.

Acacia’s Bright 400ZR+ pluggable coherent optical modules can plug into Cisco routers, enabling Arelion’s further adoption of the simpler and more scalable architecture of routed optical networking, combining innovations in silicon, optics and routing systems.

This architecture simplifies the network layer stack and meets the increasing bandwidth demands of Arelion’s customers while it reduces capital and operational expenditures.

Through the demonstration of 400G coherent connections, Arelion demonstrated the interworking of brownfield long-haul applications built with third-party optical line systems. Arelion will continue its organic expansion providing its service provider and enterprise customers with the opportunity to improve customer experience, efficient connectivity investment and better pricing.
