A METHOD AND ARRANGEMENT FOR INSTALLING OPTICAL FIBRE CABLE ELEMENTS

摘要

The present invention relates to a method and to an arrangement for installi ng in a duct optical fibre cable elements, such as combined groups of optical fibre ribbon cables. In order to enable the cable element to be blown into a duct (11), an optical fibre ribbon cable body (1) that has electrical contact devices provided at one end thereof and whic h comprises a plurality of optical fibre ribbons (2) placed one upon the other has been held together with helically wound elastic rape (3) with successive turns of the tape mutually overlapping. The external helical cross-surface thus obtained can be acted upon by a by-passi ng air stream, such as to drive the cable body forwards in the duct.
