Alcatel-Lucent and T-Mobile Czech Republic have successfully completed a trial of 400 gigabits-per-second data transmission over an existing network in the Czech Republic, paving the way for new high-speed ultra-broadband services. The first Czech trial of 400G-speed data transport is running on the existing network between Prague and Hradec Králové.
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 – is aimed at demonstrating 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. For the trial, Alcatel-Lucent used its 1830 Photonic Service Switch (PSS) together with the 400G Photonic Service Engine (PSE) over the 320km.
