Telekom Austria tests 400G

The Telekom Austria Group has successfully tested the 400G high-speed technology between Zagreb in Croatia and Ljubljana in Slovenia, demonstrating once again its innovative strength.

This field trial was conducted between February 24 and March 6, 2014 and focused on testing the 400 Gbps technology on already existing fibre optic cables.

“The continuing increase in data volumes in the years to come will require the timely planning of new technologies over long-distance networks. The use of digital services will become increasingly important going forward. The smooth transmission of voice telephony, mobile and fixed net Internet as well as high-definition cable television is an important precondition to be able to meet the needs of an ever-growing customer base,” said Gunther Ottendorfer, chief technology officer, Telekom Austria Group.

High-speed transmissions demand increasingly powerful networks between the most important hubs, not only within Austria, but also at an international level. Especially for companies operating on a global scale, a high-quality network is imperative.

Against this backdrop, Telekom Austria Group’s high-performance backbone networks play a crucial role particularly for services such as business applications e.g. bank transactions, CRM and SAP systems, which are of utmost importance for Wholesale customers.

This is why the group seeks to test technologies in corresponding field trials as early as possible to be sure it can make important timely decisions for future network planning. In this way, investments in high-speed technologies and high-performance networks for the coming decades can be best prepared.

Jointly with its longstanding technology partner Alcatel-Lucent, Telekom Austria Group’s experts and technicians were able to demonstrate via this field trial that, between the capitals Zagreb and Ljubljana, it is possible to achieve a fourfold increase in data rates from 100 Gbps to 400 Gbps using already existing fiber optic cables.

Luis Martinez Amago, president, Europe, Middle East and Africa of Alcatel-Lucent said, “This is the latest in a growing number of trials that show how our 400G Photonic Service Engine can boost the performance of today’s optical transport networks. Alcatel-Lucent’s 400G solution will help the company ensure the reliable transport of high-demand residential and mission-critical business services.”

The performance and agility of the Alcatel-Lucent 400G solution, based on the 1830 Photonic Service Switch (PSS) and the Photonic Service Engine (PSE), delivers increased capacity to support growing and dynamic packet-based services in the most efficient and cost-effective way.

Under the motto “Greentouch Initiative” the 400G transport is reducing power requirement by 47 percent and space requirement by 65 percent versus the current 100G technology. Also 400G quadruples the current wavelength capacity from 100 to 400G and thus increases total capacity up to 15.4 Terabyte.

As a first mover, the Telekom Austria Group launched the first commercially available 100G network in Europe in the spring of 2013. The main routes between Frankfurt and Sophia currently utilize a good capacity. The data volume of these 100G transmission lines was acquired by three large customers just three months after the launch of operations.
