The fiber optic cable is pulled too tight

Exceeding a fiber optic cable's maximum pulling tension permanently damages aramid strength members and induces microbends that increase link loss. This guide covers tension limits by cable type, proper pulling grip attachment, compatible lubricants, and installation. Fiber optic cable is strong, reliable and built for long-term performance, but it still needs to be handled correctly during installation. Most fiber damage does not come from normal operation after the system is live. It happens during installation, when excessive pulling force, tight bends. The light produced by fiber optic lasers is invisible to the human eye. It is crucial to form a conscious habit of absolutely never looking directly into that end face. It's. The basic approach to pulling fiber-optic cable and copper cable is similar; however, optical fiber has a few idiosyncrasies. Unlike copper, fiber is delicate glass that demands respect and precision.
