13

Borings

SITS carries out piloted borings (on curves) up to 11 cm in diameter and horizontal borings (without curves) up to 1 metre in diameter

14

Work between tracks

SITS carries out construction work between tracks by means of sheet piles that do not destabilise the track roadbed.

15

Temporary relocation of networks

SITS temporarily relocates networks by using tancarvilles.

What is a tancarville ?

When a task requires relocation of live cables, SITS possesses specific know-how in creating structures known as tancarvilles that relocate these cables onto an above-ground structure to protect them.

Installation of cables and fibre optics along railway tracks

Our railway civil engineering company is specialised in the installation of cables and HDPD tubes for fibre optics along railway tracks. With its mastery of the installation of copper cables and fibre optics, SITS plays a major role in railway signalling, the deployment of broadband networks for telecommunication operators and the creation of infrastructure for high-tension power transmission.

Methods for inserting fibre optics and microfibres in tubes

The demand for bandwidth and therefore for fibre optic lines is growing continuously. For the installation of fibre optics over great distances, our railway civil engineering company masters two phases :

  1. The installation of  high density polyethylene (HDPD) tubes.
  2. The insertion of fibre optics in these tubes by using either air or water.

We possess special competence in the insertion of fibre optics in tubes over long distances, by using either air or water; SITS was the pioneer for these methods in France starting in 1997.

Micro-tubing

SITS has also developed the method known as micro-tubing – the installation of microfibres in micro-tubes – for the major French telecommunication operators.

Connection of fibre optics over long distances with BPS.com

Thanks to its subsidiary BPS.com, the SITS France group possesses specific know-how in connecting, testing and measuring fibre optics.

In the context of installing telecommunication networks, the SITS France group thus offers a complete service range to its customers.

A path of least resistance for telecommunication operators

For a telecommunication operator seeking to reinforce its fibre-optic network, a railway line offers a direct path between cities with a single owner, limited access, few hard surfaces and few conflicts with other networks.
