Back Tension Ratio is the measure used to describe the tension on the trailing end of a cable after a pulling operation and how that tension relates to the pulling force or the cable’s rated limits. This concept is essential because it helps ensure that the act of pulling the cable doesn’t overstress the cable once it’s in place, especially at entry points, around bends, or near terminations. By monitoring and controlling this ratio, field crews can adjust pulling speed, use lubrication, add slack, or alter routing to keep the back tension within safe bounds, protecting the cable’s integrity and the reliability of the installed link. The other listed terms aren’t standard terms used in outside plant tension calculations, so they don’t describe this commonly used safety and integrity-check metric.
