Infinera (NASDAQ: INFN) and Northern European digital infrastructure provider GlobalConnect say they have conducted a successful field trial of 300- and 400-Gbps coherent transmission technology. The exercise was conducted on a metro network in Oslo, Norway, with a 50-GHz wavelength grid, alongside existing 10-Gbps channels.
The collaborators used an Infinera Groove G30 as the transport platform to support 300-Gbps and 400-Gbps alien wavelength use cases across an infrastructure originally engineered for 10-Gbps wavelengths using on/off keying (see “Denmark's GlobalConnect taps Ciena for 10-GbE network”; the service provider also has worked with Cyan and Transmode). The trial demonstrated the ability of GlobalConnect’s existing fiber network to gain additional capacity through this method.
