Sanef renews the maintenance of its motorway network’s optical fibre

Sogetrel Group has been chosen by Sanef, the French freeway concessionaire, for the maintenance of its fibre optic motorway networks in 5 lots spread over different geographical areas. These independent networks allow for private and secure connection of tolls, video surveillance systems, power supply for various stations and many other jobs. This will allow road users to enjoy the best conditions of safety and fluidity.

Highly qualified technical teams

Sanef’s mission is to promote the sustainable mobility of goods and people and to contribute to the dynamism of the regions through its networks and toll solutions. It is in this context that we have won the entire curative maintenance of the fiber optic infrastructures on all of Sanef’s operating networks. This contract is a one-year framework agreement renewable for a maximum of three years.

The service represents 50 interventions per year, which requires the establishment of highly qualified technical teams on call 24 hours a day for connection, maintenance, civil engineering and re-commissioning of the optical fiber network. The objective? Guarantee the continuity of the network within the allotted time.

The national management of the project is carried out from the Ile-de-France via our Mobility expertise center. Sogetrel commits itself to provide Sanef with a dedicated storage center on each motorway axis of the 5 winning lots.

RATP overhauls its antenna and radio equipment on its entire network

Sogetrel Group, a historical partner of RATP for the deployment and maintenance of its communication networks, has been entrusted with a maintenance mission for RATP's antenna and radio equipment within the framework of a 3-year contract.

A specific know-how

New illustration of our expertise in the field of radio: the RATP entrusts us with the preventive and corrective maintenance and the small works associated with its antenna systems and radio equipment (PMR, TETRA, 3RD, UIC, Acropol, Wifi, GSM, 3G/4G). This will allow us to continue our development in the “non-operator” telecom segments.

The contract provides for maintenance and remote maintenance on the entire RATP network through the control and preventive and corrective maintenance of antenna infrastructures. In the event of a breakdown, our teams will guarantee continuity of service and ensure that the equipment is restored to operational condition.

RATP will have a centralized management of all requests thanks to a single contact person, associated with a team entirely dedicated and led by our Mobility expertise.

Voies Navigables de France deploys optical fiber on the river network

While Voies Navigables de France (VNF) and the State have signed a contract of objectives and performance until 2029, waterways are more than ever at the heart of the ecological transition. Part of the credits is allocated to the deployment of the optical fiber along the Briare canal (45) for the motorized section. A mission entrusted to the Sogetrel Group.

Quality and reliability

VNF has chosen us for the connection of the locks in optical fiber over 14 km along the Briare canal for the motorized section.

The objective? Facilitate infrastructure management while improving the quality and reliability of the service provided (network monitoring, automation and remote control of locks and mobile points). Our service includes the supply of optical fiber, but also the drawing of the fiber in existing ducts, the installation of a drawing chamber in front of the works, the connection within the works with the corresponding protections and, finally, the commissioning tests.
