Title (EN) OPTICAL FIBRE CABLE
(FR) CABLE A FIBRES OPTIQUES
Abstract:
(EN) An optical cable comprises a strength member (1) extending along the cable, an extruded plastics sheath (5, 5') that envelops the strength member and contains at least one tubular passage (2, 2') in which is loosely housed at least one optical fibre (3), the strength member (1) and the sheath (5, 5') being non-concentric. The cable may be terminated by: (i) cutting the sheath (5, 5') circumferentially with a single cut which cuts or scores any tube located in the sheath that defines the or each tubular passage (2); (ii) breaking or kinking the strength member (1) by bending; and (iii) removing the sheath (5, 5') to expose the or each optical fibre(s) (3). The cable is relatively inexpensive to manufacture and can be terminated in a relatively simple manner at a customer entry enclosure.
(FR) Câble à fibres optiques comprenant une armature (1) qui s'étend le long du câble, une gaine de plastique extrudée (5, 5') qui enveloppe l'armature et qui contient au moins un passage tubulaire (2, 2') renfermant au moins une fibre optique (3) dans une structure libre, l'armature (1) et la gaine (5, 5') étant non concentriques. La terminaison du câble peut se réaliser de la manière suivante: (i) en coupant la gaine (5, 5') à sa périphérie par une seule entaille ou encoche qui sectionne le ou les tubes se trouvant dans la gaine qui définit le ou chaque passage tubulaire (2); (ii) en cassant ou en déformant l'armature (1) en pliant le câble; puis (iii) en retirant la gaine (5, 5') pour mettre à nu la ou les fibres optiques (3). Le coût de fabrication du câble est peu élevé et le raccordement à une borne d'entrée d'abonné est relativement simple à réaliser.
