Théâtre National Populaire de Villeurbanne - FRANCE

The TNP requires a complex topology, due to the geographical distribution of the working spaces.
The main site is joined to the Becker site (little stage) by a long tunnel. The stocking spaces are partly underground. The site has several different levels.

Each site has to allow a UHF intercommunication for the technical teams in charge on 3 distinctive networks (machinery, sound and lights) + 1 network for the control room

A technician who moves between the two sites must be able to inter-communicate with other members of his team.

Remains quite a sizable problem: how to reach over the 100 meters mark which goes from the main site to the Becker site?




Réponse Overline

A network of 'coordination little stage' and a network of 'coordination large stage' are created, allowing the users of those 2 networks to stay in inter-communication on the entire venue.

The 2 transmitters UC TX have to distribute their respective signals over the 2 sites. Overline has developed a ultra linear optical modulator/demodulator system, enabling the conversion of UHF signals into optical signals without digital conversion.

This system using the optical fiber technology enables the transportation of UHF antenna signals without any losses on a distance of more than 20km.

Single-mode optical fiber links the 2 sites.
Overline Systems uses this technology solution to ensure the antenna signal distribution over the 2 sites.
