ALU and T-Mobile Conduct 400G Network Trial

Alcatel-Lucent and T-Mobile Czech Republic have successfully completed a trial of 400 Gbps data transmission over an existing network in the Czech Republic. The trial will enable the operator to upgrade its networks, thus paving the way for new high-speed ultra-broadband services. This is the first trial of 400 Gbps data transport using existing network between Prague and Hradec Králové to obtain an advanced technical solution for the delivery of high capacity services in Czech Republic.

T-Mobile Czech Republic is rolling out mobile broadband services across the country and expects 97% of the local population to be covered by 3G and LTE networks, by the end of this year. The trial – over a distance of 320km – aimed to demonstrate the ability of T-Mobile’s existing network to meet increasing consumer demand for data capacity as well as provide even higher capacity enterprise and wholesale services in future.

The trial used Alcatel-Lucent’s 400G agile optical networking technology over T-Mobile’s existing dense wave division multiplexing (DWDM) network infrastructure, demonstrating how optical networks are able to evolve to meet future demands without the need for huge infrastructure investments.

Alcatel-Lucent used its 1830 Photonic Service Switch (PSS) together with the 400G Photonic Service Engine (PSE) over the 320km for the trial. The 400G PSE – developed by Alcatel-Lucent’s research arm, Bell Labs – dramatically boosts the performance of today’s 100G networks, laying the foundation for 400G-speed transport in the future while minimizing space and power requirements.

Alcatel-Lucent’s 400G technology allows operators to scale without costly reengineering or the need to expand their footprint, enabling a fourfold increase in density over current 100G solutions. 400G technology effectively enables the transmission of the data capacity equivalent of 88 Blu-ray Discs in a single second.
