This is a 10m LC (male) to LC (male) yellow duplex plenum-rated fiber patch cable. OM2 cables have a standard jacket color of orange and a core size of 50m. They support 10 Gigabit Ethernet for lengths measuring up to 82 meters but are more commonly used for 1 Gigabit Ethernet applications. This plenum-rated cable is the only cable allowed in spaces defined as air plenum-rateds such as raised flooring systems and air handling ducts. Plenum-rated cables must self-extinguish and prevent re-ignition. 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. Our products are guaranteed by federal law to not affect or void OEM warranties.
