GlobalConnect completed successful 400G coherent transmission with metro

Infinera and GlobalConnect completed a field trial over 50 GHz that demonstrated seamless interoperability with deployed metro transport infrastructure.

Infinera and GlobalConnect announced that they completed successfully a field trial demonstrating 400 gigabits per second (400G) coherent transmission over a 50 gigahertz (GHz) fixed grid metro transport network concurrently with pre-existing 10G channels. GlobalConnect boosted the capacity of a 10G-engineered OOK-based network by going from 10G to 400G per wavelength while increasing the fiber capacity to 32 terabits on an existing 50 GHz fixed grid metro network. They conducted over a live GlobalConnect optical link in the Oslo metropolitan area using the Infinera Groove G30 Compact Modular Platform.

Meet growing capacity demands

This field trial also shows GlobalConnect’s ability to efficiently and cost-effectively scale its current optical transport network to meet growing capacity demands while preserving its investment in deployed infrastructure with leading-edge optical technology from Infinera.

They made error-free testing, including multiple 300G and 400G alien wavelength transmission use cases over a live metro network link initially designed for and currently running 10G wavelengths using on-off keying (OOK) modulation technology.

GlobalConnect, which owns 42,000 km fiber network and 18,000 sqm high-security data center space in Northern Europe, provides the foundation for a wide range of carrier-class services for wholesale and corporate customers. Anders Kuhn Saaby, CTO, GlobalConnect said,

“With the explosive growth in data traffic and acceleration of digital transformation, optical network flexibility and scalability remain critical to our ability to be responsive to our customers’ evolving communications needs,” said “We remain committed to advancing our fiber infrastructure with cutting-edge technologies to keep pace with growing capacity demands and allow us to expand our addressable market.”

The Infinera Groove G30 is an open, disaggregated networking solution that compatible with third-party optical line systems and diverse network environments. These solutions include conventional 10G-engineered non-coherent metro networks designed with OOK, a legacy transport technology that poses limitations for upgrading to higher-capacity wavelengths.

Glenn Laxdal, Senior Vice President of Disaggregated, Edge, and Access Solutions at Infinera, said:

“We were pleased to work with GlobalConnect to showcase the state-of-the-art performance of our Groove G30 compact modular solution.”

“This solution helps network operators eliminate the technology roadblocks to seamless scaling of conventional 10G network infrastructure to meet higher-capacity customer demands cost-effectively.” he added.
