  • Method and arrangement for installing optical fibre cable elements
    Patent number: 6341188
    Abstract: The present invention relates to a method and to an arrangement for installing in a duct optical fiber cable elements, such as combined groups of optical fiber ribbon cables. In order to enable the cable element to be blown into a duct (11), an optical fiber ribbon cable body (1) that has electrical contact devices provided at one end thereof and which comprises a plurality of optical fiber ribbons (2) placed one upon the other has been held together with helically wound elastic tape (3) with successive turns of the tape mutually overlapping. The external helical cross-surface thus obtained can be acted upon by a by-passing air stream, such as to drive the cable body forwards in the duct.
