• Colt demonstrates how Nokia’s sixth generation super-coherent Photonic Service Engine  can be used to quickly add scale and performance to optical networks.
• Colt delivers new 800G high-speed line capacity over existing open optical line system using Nokia’s PSE-6s platform.

Nokia announced that Colt Technology Services, a global digital infrastructure company, successfully trialed Nokia’s sixth generation super-coherent optics to increase the scale and performance of its optical network. Using Nokia’s PSE-6s solution, Colt successfully completed a long-haul production network trial achieving 800G line capacity over a 1,500 Km network connecting Madrid, Spain to Lisbon, Portugal. This capability will enable Colt to increase the capacity while reducing the total cost of ownership and improving power efficiency.

With the proliferation of bandwidth-hungry applications like streaming, cloud computing and 5G services, operators are having to continually upgrade their network capacity to meet the rising demand for data and new high speed services. Next generation coherent optics like Nokia’s PSE-6s can help operators meet this challenge by significantly increasing the data-carrying capabilities of its existing optical infrastructure.

Deployed over real-world conditions, including aerial fibre cables, as an alien wavelength, over 22 spans involving ROADMs in CDC configuration, Colt was able to achieve 800Gb/s data transmission over a 1,500km fibre network. Nokia’s PSE-6s stands ready to support future 800G customer demand in addition to 400G and 100G applications. With this trial, Colt takes the next step to augment its optical network with next generation data transport capability and meet future customer demands.

Rafael DeFermin, SVP Network Infrastructure, Europe Regional Business Center at Nokia, said: “With data volumes growing exponentially every year, there continues to be an increased focus by operators on the cost and power consumption per bit. But it’s not just about meeting the demands of today’s networks, it’s also about shaping the future of connectivity. Nokia’s PSE-6s solution allows operators like Colt to position themselves at the forefront of the industry and use their existing network to deliver the unmatched speed, efficiency and reliability essential for meeting both current and future evolving customer demands.”

Vivek Gaur, VP of Network Engineering at Colt, said: “This trial highlights our commitment to work with our technology partners to provide scalable and flexible high-bandwidth services across our entire optical network backbone. We are excited by the results of Nokia’s of PSE-6 super coherent optics and see their solution as an important enabler to effectively stay ahead of demand for new high-speed optical services.”
