Alcatel-Lucent Enhances 100G Transmission with Coherent Detection

Alcatel-Lucent enhanced its optical networking portfolio with next-generation coherent technology for dealing with transmission impairments, which become extremely severe at speeds higher than 100 Gbps. The technology uses proprietary algorithms in digital signal processing. It has been demonstrated in a 112 Gbps field trial over an existing, heavy loaded real-traffic fiber link of Telefonica's network during which live traffic was transmitted over 1,088 km between four cities, in Spain.


Alcatel-Lucent is implementing next-generation coherent detection in key optical platforms with the goal of helping service providers transform their existing networks to ease the strain caused by high bandwidth applications, while maintaining superior performance. Additionally, the technology will seamlessly support further evolution to higher speeds than 100G over the same future-proof platform when the market dictates.


Alcatel-Lucent said its optical networking portfolio allows for dynamic wavelength assignment and restoration, as well as transmission of any hybrid traffic mix. Ensuring the optimized use of existing fiber plants, it can transmit mixed 10, 40 and 100G signals without the need for guard bands or network reengineering, and traverse multiple nodes without additional regeneration. As a result, operators can implement highly-flexible and scalable meshed transmission networks to cost-effectively carry services in response to end customer demands, today and in the future.


"The advancements to our optical portfolio further confirm the role of optical networking as a critical enabler for competitive transformation to seamlessly move to higher capacities fast and reliably," said Romano Valussi, president of Alcatel-Lucent's Optics activities. "In combination with our customer focus is set to help operators accelerate time to service for new applications, simplify their operations and improve performance for better total cost of ownership."http://www.alcatel-lucent.com
