ABSTRACT:
A cable comprises a leakproof tube containing at least one optical fiber together with a filler material which holds the fiber(s) in place inside the tube and which provides the tube with longitudinal sealing. The filling ratio of the fiber-holding material is less than a determined limit so as to provide at least one expansion volume inside the tube so that the partial pressure of hydrogen remains low enough to avoid giving rise to significant attenuation in the transmission properties of the optical fiber.
