Coriant has its roots in the Transmission Technology department of Siemens based in Munich, Germany, which was known as Übertragungstechnik (ÜT) in the 1990s.

In the 1990s, the technology at Siemens evolved from Plesiochronous Digital Hierarchy (PDH) to Synchronous Digital Hierarchy (SDH) at the STM-4 / STM-16 level, which offered transmission capacity of 2.5 Gbit/s.

This marked a significant shift towards higher transmission capacity, paving the way for future advancements.

The late 1990s and early 2000s saw the emergence of DWDM, which enabled even higher transmission capacity in the terabit per second region.

DWDM is also known as optical transport network (OTN), where a set of multiplex and encapsulation hierarchies is standardized.

Infinera has made a significant move by acquiring optical transport firm Coriant for $430 million. This acquisition will create one of the world's largest optical network equipment providers.

The combined company will have a powerful portfolio to support customers' transition from 4G to 5G, from Optical Transport Network (OTN) to packet and from closed to open network architectures.

Infinera expects the acquisition to approximately double its revenue. This is a significant boost for the company, especially as the next wave of global network spending begins.

The acquisition will also expand Infinera's customer base to serve nine of the top 10 global network operators and the top six global internet content providers. Five new network operators and three new internet content providers will be added to Infinera's customer base.

The combined company will benefit from Coriant's significant investments in software automation and open, disaggregated solutions, which have gained significant traction and wide-scale adoption by customers around the world.

Tom Fallon, CEO of Infinera, sees this acquisition as a fantastic opportunity to strengthen their ability to serve the world's largest network operators.

Telia Carrier has deployed Coriant 400G-capable technology in its pan-European backbone network.

This upgrade will enable Telia Carrier to double the capacity on its DWDM infrastructure.

The Coriant CloudWave Optics coherent interface technology is a key photonic layer technology that combines a leading signal processing engine, optimized integrated photonics, and embedded software intelligence.

This technology brings a new level of optical performance, efficiency, and scalability to infrastructure networks facing unprecedented traffic growth.

A 400G-enabled fiber route between Copenhagen, Denmark and Frankfurt, Germany is the first implementation of Coriant CloudWave Optics in Telia Carrier’s pan-European backbone network.

This solution will also enable Telia Carrier to maximize reach and performance throughout their wider network, including across challenging fiber routes like subsea long haul transmission to London.

The Coriant solution enables Telia Carrier to significantly improve utilization of its existing DWDM infrastructure and rapidly provision new services to meet customers’ dynamic connectivity requirements.

Telia Carrier’s Chief Technology Officer, Mattias Fridström, notes that the Coriant solution will help the company unlock the full potential of its DWDM infrastructure.

Coriant is pleased to extend its long-standing relationship with Telia Carrier and continue to deliver technology innovation that allows them to unlock the full potential of their DWDM infrastructure.

The Coriant solution demonstrates the real-world value of optical layer programmability and fast service deployment.
