Tensile force of aerial optical cable
For fiber optic cable, the tensile strength of a cable represents the highest load or pulling force that can be placed upon any cable before any damage occurs to the fibers or their optical properties and characteristics. Planning for proper clearances requires knowing the "sag" characteristics of the proposed installation. 26 describes characteristics, construction and test methods of optical fibre cables for aerial application (including lashed cables), but does not apply to optical ground wire (OPGW) cables or metal armour self-supporting (MASS) cables. Tension and Sag The 2007 National Electrical Safety Code (NESC) addresses Tension and Sag in Sections 235. These cables are normally provided with a metal laminate,( aluminum foil or corrugated steel tape), to protect them against moisture. 3 OFS MiDia® FX plus and DuctSaver® FX cables are designed specifically for blown cable applications in underground plant.
