France Telecom-Orange is upgrading its optical fiber network linking Paris and London using 100G technology from Alcatel-Lucent. The deployment follows a field trial in the autumn on the 720 km Paris-London route, which was already supporting 10 Gbps channels. For this trial, Alcatel-Lucent enhanced its existing 1626 Light Manager with 100G next-generation coherent technology through the 1830 Photonic Service Switch (PSS).
Didier Duriez, Senior Vice President International and Backbone Networks Factory at France Telecom-Orange said: “the deployment of a 100G optical transmission demonstrates our Group’s commitment to improve the performance of our networks on a long-term basis in order to address the exponential bandwidth needs of our customers. 100G technologies can expand the data capacity of our existing fiber links to the multi-terabit capacity necessary to handle exploding traffic growth over longer distances, with an optimized investment.”

- Earlier this month, Alcatel-Lucent announced a series of improvements to its single-carrier, 100G coherent technology that enables optical waves to travel up to 30% farther, even over poor quality fiber, while opening up many more use cases for 100G optical transport links.
The gains, which are achieved using improved signal processing algorithms developed by Bell Labs for overcoming impairments in the fiber, are being delivered in a 100G eXtended Reach (XR) card for the Alcatel-Lucent 1830 Photonic Service Switch (PSS). The platform is now able to transmit a combination of 10G, 40G and 100G rates on different wavelengths of an optical fiber for up to 2000 kilometers and beyond — representing up to a 30 percent increase in reach.
