This is a 3.0 m (9.8 ft) LC (male) to LC (male) aqua duplex riser-rated armored fiber patch cable. An OM4 cable has a core size of 50 m microns that supports 10 Gigabit Ethernet at lengths measuring up to 550 meters, and 100 Gigabit Ethernet measuring up to 150 meters and is reverse compatible with OM3. This optical fiber, nonconductive, riser (OFNR) cable is best suited for use in interior fiber-optic applications. A duplex cable is a two-strand fiber optic patch cable that works best with transceivers that both transmit and receive.
