  • Patent number: 7471861
    Abstract: Between an optical fiber (LF11, LFB12, LFB13) and a surrounding core covering (AH11, AH12, SB13) of an optical transmission element (OE11 to OE13) there is at least one dry and compressible fixating element (FE11 to FE13), which surrounds the optical fiber totally or partially, and which exerts a defined contact pressure against the core covering and against the optical fiber for fixating the optical fiber in the longitudinal direction of the transmission element. The fixating element is further formed and positioned in such a way, that position changes of the optical fiber due to bending or elongation are possible. In this way, unallowable attenuation increases in the optical fiber due to bending or position changes can be avoided.

  • Publication number: 20080080821
    Abstract: Between an optical fiber (LF11, LFB12, LFB13) and a surrounding slot element (AH11, AH12, SB13) of an optical transmission element (OE11 to OE13) there is at least one dry and compressible fixating element (FE11 to FE13), which surrounds the optical fiber totally or partially, and which exerts a defined contact pressure against the slot element and against the optical fiber for fixating the optical fiber in the longitudinal direction of the transmission element. The fixating element is further formed and positioned in such a way, that position changes of the optical fiber due to bending or elongation are possible. In this way, unallowable attenuation increases in the optical fiber due to bending or position changes can be avoided.

  • Publication number: 20020136510
    Abstract: A hybrid cable with optical fibers and metallic conductors has a cable jacket with a first slot (14) for reception of optical fibers (121, 122) as well as a second slot (24) for reception of the electrical conductors (221, 222). The parts (1, 2) of the cable jacket forming the slots are connected to one another with a crosspiece. The cable has a preferred bending line, which is formed by the symmetrical axis (4) of the cable. The cable is especially suited for optical signal transmission in combination with the transmission of electrical data signal or supply voltage.
