During the run-up to what was expected to be a busy OFC 2020 Conference and Exhibition over the past few months, optical equipment manufacturers have been preparing 800G single wavelength coherent solutions for production. Several companies have shared information on recent 800G trials in live carrier networks and have released details of their 800G solutions that are production-ready and will be deployed in carrier networks over the coming months. The introduction of 800G coherent is a significant development supporting throughput per wavelength on metro links that is one third faster than the 600G coherent solutions introduced just two years ago and four to eight times faster than the 100/200G coherent links widely used today.
