A Fiber Optic Longitudinal Slitter is a precision-engineered mechanical device designed to slit the outer jacket of fiber optic cables along their longitudinal axis. It easily slits the PVC cable jacket into two haves before crimping, in both field and plant applications, time is saved and consistency is resulted with this precise and innovative tool. Tool. Safely slit and ring fiber optic and armored cables (4-10mm OD). These cutting shears feature the following: JIC-186 Kevlar Shears, Adjustable Joint Screw, Serrated Blade for Gripping JIC-190 Flush Cut Kevlar® Cutters. A fiber cable sheath longitudinal and horizontal cutter is an indispensable tool for fiber optic technicians, ensuring clean and efficient stripping of the cable's protective sheath for installation, maintenance, and repair tasks.
