This is a 2m LC (male) to SC (male) orange duplex plenum-rated fiber patch cable. An OM1 cable has a core size of 62.5 microns that can support 10 Gigabit Ethernet at lengths measuring up to 33 meters. It is most commonly used for 100 Megabit Ethernet applications. This plenum cable is the only cable allowed in spaces defined as air plenums such as raised flooring systems and air handling ducts. Plenum 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.
