    Single-mode fiber splicing requires quite a precise core alignment for the adjustment of core eccentricity and outer diameter discrepancies. Several core alignment methods have been developed. The typical four methods are as follows: 1) remote injection and remote detection systems (RIRDS), 2) remote injection and local detection systems (LDS), 3) local injection and detection systems (LIDS), 4) c...

    This paper reports the results of a study aimed at understanding the design process for fiber optic systems in subscriber lines, also known as loop network. Since loop spans are typically shorter and traffic volumes lower than interoffice trunks, the required performance level of a fiber optic system is often less than the maximum Obtainable from the technology. This affords us an opportunity to s... View full abstract»

  • Applications of Optical Fibers for Overhead Transmission Lines

    Publication Year: 1986, Page(s):699 - 705
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (712 KB)

    Optical fibers are increasingly in use for overhead transmission lines. Optical fiber cables for overhead transmission lines can be classified into three types; composite type, winding type, and self-supporting type. For the composite type, an FRP-covered optical fiber unit is suitable because of its good thermal and mechanical characteristics. Winding-type fiber cable is least expensive to instal...

    When using an OTDR, fault-locating accuracy can be improved if the nature of the fiber discontinuity can be taken into account in estimating the true distance to the fault. Basically, two types of faults can be encountered: reflective and nonreflective faults. Recognizing that the slope of the rising part of the back-reflected pulse is a function of the optical reflectivity at the fault, a scheme ... View full abstract»

  • Meeting the Fiber Optic Challenge with Vibratory Cable Plows

    Publication Year: 1986, Page(s):693 - 698
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (816 KB)

    To date, much of the installed direct buried fiber optic cable has been placed by large crawler-mounted plows. However, in many areas, such as along highway rights-of-way and other routes with numerous road crossings, smaller-sized rubber-tired machines would be advantageous. Four-wheel drive vibratory cable plows have been utilized extensively by the telecommunications industry when installing co... View full abstract»

    Because of the present emphasis on placement of long unspliced lengths of fiber optic cable, conventional lubricants are being pushed to their limits. This paper discusses an installation where a newgeneration lubricant, consisting of silicone oil and tiny plastic ball bearings, was used to lower the effective coefficient of friction to 0.09. This allowed the contractor to place fiber optic cable ... View full abstract»

    When installing junction optical fiber cable, which essentially must be longer than conventional metallic-conductor cable to effectively reduce splice loss, the applied tensile load must be within tolerable limits to prevent an increase in loss and a decrease in lifetime. It has recently become possible to meet this requirement through the development of a new cable installation system which makes... View full abstract»

    A radically new approach to optical fiber cable design and installation is described. Packages containing a number of optical fibers were drawn into preinstalled empty bores (tubes) using the viscous drag of air. The drag force acting on the fiber package is distributed along its length, which makes it possible to introduce fibers into complicated routes, with low strain. In this paper, we will co...

    The problems of splice closure are discussed briefly and the options available for optical fiber cable systems are reviewed. It is concluded that for long-haul point-to-point cables, absolute security is paramount, and that for these, welded splice closures should be used. For optical fiber cables in local distribution networks, however, closures which can easily be reentered are needed. This requ... View full abstract»
