Abstract
Abstract In order to protect electrical and fiber optic cables in a central telephone office terminal equipment frame, the cables are controlled and managed so as to be releasably retained in a service loop within a fiber management panel. The releasable retention is performed by a stretched extension spring selected, dimensioned and stretched in such a manner with respect to the diameter of the cables that each cable can be gently but firmly retained when pressed into the gap between adjacent coils. The retention spring permits emergency release of the cable in the event of mishandling of the equipment by service personnel.
