The pulling force must be kept below a designated limit for the specific cable being installed. For outside plant (OSP) fiber optic cables, the limit is usually 600 pounds. They operate in -60°C to +85°C temperatures. Proper tensile strength testing helps you prevent cable damage and maintain network. Here is a brief answer. Understanding key cable specifications assists. Fiber optic cable is strong, reliable and built for long-term performance, but it still needs to be handled correctly during installation. It happens during installation, when excessive pulling force, tight bends. Sufficient excess cable is needed to allow splicing in a controlled environment, usually a splicing trailer, and the storage of excess cable must be considered in the planning stage.
