This is a 1m FC (male) to LC (male) aqua duplex riser-rated fiber patch cable. An OM4 cable has a core size of 50 microns that can support 10 Gigabit Ethernet at lengths measuring up to 400 meters. It is most commonly used for 10 Gigabit Ethernet applications. 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. Our patch cables are 100% compliant for all of your networking needs.
