Rosenberger OSI installs highly effective fiber optic solution for transmission system operator TenneT


Utility company now benefits from state-of-the-art IT technology from the cabling specialist in its control centers

Augsburg, January 14, 2020 – Rosenberger Optical Solutions & Infrastructure (Rosenberger OSI), manufacturer of innovative fiber optic cabling infrastructures in Europe, has completed an extensive fiber optic project for the utility company TenneT. Rosenberger OSI has implemented several workstations and training workplaces in TenneT's control room as part of a concept for seamless monitoring of the operating status of its networks and interaction with the data center. Among other things, PreCONNECT® SMAP-G2 19” distribution panels as well as OM4 PreCONNECT® STANDARD Trunks were used. 

TenneT is one of the leading transmission system operators (TSOs) for electricity in Europe. The utility company employs more than 4,500 people and operates about 23,000 kilometers of high-voltage lines and cables. Around 41 million households and companies in Germany and the Netherlands are supplied with electricity via the power grid. The company has set up monitoring control centers at locations in northern and southern Germany to ensure secure network operation around-the-clock. 


Monitoring the operating status

In order to guarantee network availability and security in the future, TenneT launched the "KVM Matrix" project and commissioned Rosenberger OSI to plan and implement the solution. KVM stands for Keyboard, Video, Mouse and is the basic requirement for seamless monitoring of the operating status with high-calibre monitoring and control systems. A connection between the control stations and the data center enables dedicated data visualization directly at the workstations of the control centers despite the physical distance.


Tight installation schedule

The project was implemented by Rosenberger OSI within 20 days. As part of the project, Rosenberger OSI implemented several workstations and training workplaces in TenneT's control room. In addition, there are further workstations in the back office. The various cable types were subjected to the necessary measurements before acceptance. This included the factory measurement of the fiber optic cables as well as the OTDR measurement by on-site service. The service team used 96-fiber OM4 PreCONNECT® STANDARD trunks for the connection between the control room, the data center as well as the training rooms and the office area. PreCONNECT® SMAP-G2 1HE and 2HE as well as 1HE and 2HE splice housings were used for the installation of the trunks at the corresponding cord ends, for example in the control room. Additional splicing work was necessary in order to properly implement the trunk.



Equipped for the future

“Despite the sometimes somewhat critical conditions in the installation environment, the Rosenberger OSI team has implemented our specifications in an exemplary manner,” says Patrick Bernasch-Mellech, responsible for Data & Application Management at TenneT, pleased with the completion of the work. “The individual installation steps were carried out according to our specifications within the promised time frame. The ongoing operation was not interrupted.”
