Monheim to Donauwörth

Production of local junction cable

Customer: Deutsche Telekom AG
Construction time: September 2017
During the execution period of only 10 work days 7 x 16,400 m SpeedPipes (= total length of Speednet pipes installed: 114.8 km) and 21,100 m fibre optic cable with 96 fibres were blown in.

Heilbronn to Sinsheim

Blow-in of fibre optic cable and SpeedPipes into existing pipes

Customer: Deutsche Telekom AG

New fibre optic cable with a length of around 35 km was laid between Heilbronn and Sinsheim. 53 pits for drawing had to be created over the entire distance and 17 km Speednet pipes were installed.

Various FTTC projects in southern Germany

DLR – blow-in of fibre optic bundles into compressed air pipes of main copper cable

Customer: Deutsche Telekom AG
Construction time: 2016 – 2017
This special technology makes it possible to blow fibre optic bundles into compressed air pipes in existing copper main cables with compressed air surveillance. This upgrade method helps to prevent underground engineering works in high quality surfaces and bridge existing gaps in existing routes. Up to the present about 25 km of fibre optic bundles were blown in during various FTTC projects by means of this technology.

FTTC (Fibre to the Curb) fibre optic upgrade

Customer: Deutsche Telekom AG
Construction time: March 2013 – 2018
The upgrade with fibre optic cable to the curb to the multifunctional cabinet was carried out on schedule in over 60 cities in Baden-Württemberg. The cities Tübingen, Böblingen, Ludwigsburg, Göppingen and Reutlingen were among these cities. A total of over 10,000 km of fibre optic cable, SpeedPipes, Speednet pipe bundles and composite tubing for FTTC projects of Deutsche Telekom was blown in or drawn in during these projects.

Lörrach, FTTH fibre optic cable upgrade

Customer: Deutsche Telekom AG
Construction time: March - October 2013
A total of over 220km of mini/micro fibre optic cables was blown in and over 400 km of SpeedPipes and Speednet pipe bundles were drawn in during a Construction time of about 7 months. 1,693 house connections were connected to the fibre optic network including all the required installation and measuring works, as well as fire-retarding sealings up to the “turnkey” handover to the Client.

Bettenhausen

Fibre optic cable laying of submarine cable in the pressure tunnel of a water power plant

Customer: EnBW AG
Construction time: November 2012 und January 2013
A continuous fibre optic cable was laid through the 2.84 km long pressure tunnel of the water power plant from the barrage dam Heimbach to the equipment building at the pressure pipe line in Bettenhausen. Empty conduits and power cables were also laid into the pressure pipe line, which has an incline of 62 m on almost 200 m. Due to the positive experience all splicing and installation works for the fibre optic cable were also awarded to LEONHARD WEISS.

DLR – blowing in of fibre optic bundles in small compressed air pipes

Customer: Deutsche Telekom AG
Construction time: 2016 - 2017
With this special technology fibre optic bundles are blown into existing main cables under compressed air supervision into the small compressed air pipes. This method helps to avoid underground construction works in high quality surfaces and bridge existing gaps in lines. Up to the present approx. 10 km fibre optic cables were blown in by means of this technology in various FTTC projects.

FTTC - Fibre to the Curb

Customer: Deutsche Telekom AG
Construction time: 2013 - 2018
In over 45 cities in Baden-Württemberg, like Tübingen, Ludwigsburg, Göppingen and Reutlingen the laying of fibre optic cable to the curb to the multi-function-cabinet was completed on schedule. Up to the present a total of over 6,000 km of fibre optic cables, SpeedPipes, Speednet pipe bundles and composite tubing for FTTC projects of Deutsche Telekom were blown in or drawn in.

Fibre optic cable Heilbronn - Sinsheim

Customer: Deutsche Telekom AG
Construction time: March - October 2013
Between Heilbronn and Sinsheim a new fibre optic cable was laid, which is about 35 km long. During this project 53 drawing pits were constructed over the total distance and 17 km of micro pipes were installed.

FTTH fibre optic upgrade Lörrach

Customer: Deutsche Telekom AG
Construction time: March - October 2013
A total of over 220 km of mini/micro fibre optic cable was blown in during the Construction time of about 7 months and over 400 km SpeedPipes and Speednet pipe bundles were drawn in. 1,693 buildings were connected directly to the fibre optic network, including all installation and measuring works in connection with this assignment, as well as fire sealings up to the “turnkey“ handover to the Client.
