Fiber optic cable tensile strain

Most fiber optic cables allow roughly 1,800 to 4,500 Newtons (400 to 1,000 lbf) of pulling tension, and exceeding this limit during conduit pulls risks severe microfractures and higher light attenuation. Understanding the strain transfer mechanism is required to interpret strain sensing results for fiber optic cables. Interpretation of fiber optic sensing. Fiber optics are the high-speed engines of global connection. We believe that with the right approach to structural integrity, these incredible tools can provide decades of flawless service. Proper tensile strength testing helps you prevent cable damage and maintain network.
