Page 30: Sscnet Iii Cable Laying
WIRING 3.3.1 SSCNET III cable laying SSCNET ΙΙΙ cable is made of optical fiber. Application of a power, such as a major shock, lateral pressure, haul, and abrupt bending or twisting, to the optical fiber will deform or break the inside, disabling optical transmission. - Page 31 WIRING (3) Tension Applied tension to fiber optics causes external force to concentrate in the section where fiber optics are fixed and an optical connector is connected, increasing transmission loss. If a larger pressure is further applied, this could cause a disconnection of optical fibers and a damage to the optical connector. For cable laying, handle without putting forced tension.
