Telecom network vendor Alcatel-Lucent and T-Mobile Czech Republic have completed their 400G trials.
400G data transmission trials over an existing network in the Czech Republic will assist T-Mobile Czech Republic to boost the launch of its mobile broadband services across the country. T-Mobile Czech Republic is targeting to cover 97 percent of the local population by 3G and LTE networks in 2015-end.
Vladimir Klein, CTO of T-Mobile Czech Republic, said: “Besides our existing commitments, delivering high-bandwidth access via TeraStream, it’s also key for us to permanently verify new and innovative technology options.”
The trial – over a distance of 320km – aimed to demonstrate the ability of T-Mobile network will assist in meeting growing demand for data capacity from consumers at present, enterprise and wholesale services in the 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.
The 400G PSE – developed by Alcatel-Lucent’s research arm, Bell Labs – boosts the performance of 100G networks, laying the foundation for 400G-speed transport in the future while minimizing space and power requirements.
Alcatel-Lucent’s 400G technology allows telecom 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.
Alan Ilczyszyn, territory sales manager of Alcatel-Lucent said: “These 400G technology trials show the real application of our 1830 PSS DWDM optical transport network solution in allowing providers to smoothly evolve capacity and grow as their customer demands grow.”
