This is a 2m LC (male) to LC (male) green duplex riser-rated fiber patch cable. An OM3 cable has a core size of 50 microns that supports 10 Gigabit Ethernet at lengths measuring up to 300 meters and 40 Gigabit or 100 Gigabit Ethernet measuring up to 100 meters. This riser cable is best for used in vertical tray applications such as between floors via cable risers or in elevator shafts. These cables must self extinguish. 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.
