Cutting fiber optic cables is much like cutting conventional cables, with only a slight difference. Take a sharp blade or wire strippers and cut through the jacket material, only then pull off the jacket. 1 Improper use of a respooler (Figure 1) can cause damage to a cable jacket or result in wavy fiber in tight buffered cables due to cable crossovers or excessive tensile loading. They transmit data as pulses of light through strands of glass or plastic, providing high-speed internet, seamless data exchange, and efficient signal distribution. However, due to their fragile nature, cutting. High quality heavy duty fiber cable cutters, Kevlar fiber strength member cutters, scissors/snips kits for fiber optic technicians, hot plastic fiber cutters & more. Specifically fiber used for internet.
