Dynamic characteristics of aerial fiber optic cable

A finite element model has been developed to evaluate the dynamic response of aerial fiber optic cables. The results of several dynamic excitation scenarios are presented and discussed. These include wind galloping and sudden movement of a support pole when impacted at high speed by a vehicle. Fiber optic cable splice closures attached to the support strand are potentially vulnerable under these conditions. Inertial loads derived from the computer simulations are given for evaluating the mechanical reliability of splices, splice trays, etc., contained within aerial splice closures
