A fiber optic cable suitable for indoor applications includes a core tube surrounding a plurality of coated optical fibers; a jacket formed of flame-retardant polymer material surrounding the core tube; and at least one layer of strength members disposed between said core tube and said jacket. The jacket has an outer diameter of not greater than about seven mm and the coated optical fibers experience a short-term increase in signal attenuation of no more than about 0.01 dB when the cable is looped in a radius of 5 centimeters.
La présente invention a pour objet un câble à fibres optiques convenant aux applications intérieures; celui-ci comporte un tube central enfermant une pluralité de fibres optiques enduites; une gaine, composée d'un matériau polymère difficilement combustible entoure le tube central; au moins une couche d'éléments résistants est disposée entre le tube central et la gaine. La gaine possède un diamètre extérieur ne dépassant pas environ sept millimètres et les fibres optiques sont soumises à une augmentation courte durée de l'affaiblissement du signal de moins d'environ 0,01 dB lorsque le câble est enroulé selon un rayon de 5 centimètres.
