Title (EN) MANUFACTURE OF OPTICAL CABLE
(FR) FABRICATION DE CABLE OPTIQUE
Abstract:
(EN) Method and apparatus for locating viscous water blocking material (29) beneath a tube (24) in a groove of a core member of an optical cable. The material is laid into the base of the groove and the tube inserted into the groove so as to displace the material from the base and around the tube while a space between the tube and base of the groove remains filled with the material.
(FR) Procédé et appareil pour loger un matériau (29) bloquant l'eau visqueuse sous un tube (24) situé dans un sillon de l'âme d'un câble optique. Le matériau est déposé dans le fond du sillon et le tube est introduit dans le sillon afin de déplacer le matériau se trouvant dans le fond pour qu'il entoure ledit tube, alors qu'un espace situé entre le tube et le fond du sillon reste rempli de matériau.
