White VIPER pigtail is a section of fiber optic cable with an SC APC connector on one end and cut fiber on the other end. A cable with a flat cross-section for easier pushing through shafts. LSOH coating. Tool-free stripping of the cable to any distance makes it ideal for multifamily residential units. Drop-type pigtails are most often used to connect subscriber equipment to a fiber optic network in residential and office buildings.
