US Signal Shares Results of Trailblazing 100G Network Upgrade

The 100G coherent trial was performed over an in-service 10G-engineered network between Chicago, Ill. and Kalamazoo, Mich. The successful trial confirmed that US Signal will deploy in-service, 100G coherent technology on networks originally designed for 10G transmission without any re-engineering, thereby extending the value and return on investment of the company's existing fiber network.
