  • Page 38: Instructions For Laying The Sscnet Iii Cable

    3.3.3 Instructions for laying the SSCNET III cable SSCNET III cable is made of optical fiber. Application of a power such as a major shock, abrupt bending, haul, lateral pressure, or torsion to the fiber-optic cable will deform or break the inside, disabling optical transmission. Read described item of this subsection carefully and handle it with caution.
  • Page 39  Lateral pressure Applying a lateral pressure to the fiber cable deforms the cable itself and applies pressure to the internal fiber, resulting in increase in transmission loss. If a larger pressure is further applied, the cable may be disconnected. As the same condition also occurs at cable laying, do not tighten up optical cable with a thing such as nylon band (TY-RAP).
