How to calculate the Tensile strength of a fiber optic cable? – Optical fiber cable design

A strength member is used to increase the tensile force which the cable will experience starting from manufacturing stage to the installation through ducts or directly buried or pulled through. To design a fiber optic cable, it is a must to know what elements contribute to increase the tensile force. This depends on installation methods and Standards used.
