These materials have enhanced flame-retardant qualities as compared to PVC but are much more costly. Where PVC can do the job, it’s the jacket material of choice. KEY TERM Slitting Cord Inside some UTP cable jackets is a polyester or nylon string called the slitting cord or slitting string. The purpose of this cord is to assist with slicing the jacket open when more than an inch or two of jacket needs to be removed. Some cable installers love them; many find them a nuisance, as they get in the way during termination.
6). Graded-index fiber is preferred because less light is lost as the signal travels around bends in the cable. 5/125-micron).
