This is a 100m 4xLC (male) to 4xLC (male) aqua 4-strand fiber trunk cable. An OM4 cable has a core size of 50 microns that can support 100 Gigabit Ethernet at lengths measuring up to 150 meters. It is most commonly used for 100 Gigabit Ethernet applications. This optical fiber and nonconductive cable is best suited for use in exterior 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.
