A fiber optic installation structure and method therefor includes a duct having an inner tube, at least one optical waveguide, and a jacket and is disposed within a channel of a paved surface. The jacket generally surrounds the inner tube. When the duct is disposed within a channel defined by a paved surface, a friction fit is created between the duct and the channel for holding the duct in place. Thereafter, a filling material is used for overlying the duct and at least partially filling a channel. In other embodiments, the jacket is capable of being compressed when installed into the channel. The duct may include an armor layer disposed between the inner tube and the jacket for protecting the inner tube. Moreover, at least one optical waveguide may be disposed within at least a portion of the inner tube of the duct and may be introduced after the duct is installed in the paved surface.

L'invention concerne une structure d'installation de fibres optiques et un procédé associé. Ladite structure comporte un conduit ayant un tube interne, au moins un guide d'onde optique, et une gaine et qui est disposée dans un canal d'une surface revêtue. La gaine enveloppe généralement le tube interne. Lorsque le conduit est posé dans un canal défini par une surface revêtue, un ajustement serré se crée entre le conduit et le canal, le conduit étant ainsi maintenu en place. On utilise ensuite un matériau de remplissage pour recouvrir le conduit et remplir au moins partiellement le canal. Dans d'autres modes de réalisation, on peut comprimer la gaine lorsqu'elle est posée dans le canal. Le conduit peut comporter une couche blindée posée entre le tube interne et la gaine de façon à protéger ledit tube interne. De plus, au moins un guide d'onde optique peut être posé à l'intérieur d'une partie du tube interne du conduit, il peut également être introduit une fois le conduit posé dans la surface revêtue.
