Telia, Coriant Partner on 400G Backbone

Telia Carrier and Coriant have introduced 400G-capable Coriant CloudWave Optics technology in Telia Carrier’s pan-European backbone network, starting with a Copenhagen-Frankfurt link.

The power-efficient coherent interface technology will enable Telia Carrier to double the capacity on its DWDM infrastructure and further reduce network latency for its wholesale customers.

“As our customers in Europe experience increased demand for capacity to support their business-critical applications, we are committed to investing in best-in-class innovation to stay at the forefront of service excellence,” said Mattias Fridström, CTO, Telia Carrier. “The Coriant solution enables us to significantly improve utilization of our existing DWDM infrastructure and rapidly provision new services to meet our customers’ dynamic connectivity requirements.”

The first implementation of Coriant CloudWave Optics in Telia Carrier’s hiT 7300-based pan-European backbone network will include the 400G-enabled fiber route between the cities Copenhagen and Frankfurt. With optical link control and software programmable modulation capabilities, the Coriant solution will also enable Telia Carrier to maximize reach and performance throughout their wider network, including in challenging fiber routes such as subsea long haul transmission to London, a major Internet hub in the region.

“We are pleased to extend our long-standing relationship with Telia Carrier and continue to deliver the technology innovation that allows them to unlock the full potential of their DWDM infrastructure,” said Tarcisio Ribeiro executive vice president, Global Sales and Services at Coriant. “The Coriant solution demonstrates the real-world value of optical layer programmability and fast service deployment.”
