ST/ST plenum-rated duplex 50/125 multimode fiber patch cable is specially designed for gigabit Ethernet, fiber channel, Infiniband, ATM and internet protocol applications plus its OFNP plenum-rated for in-wall use without conduit. It provides higher bandwidth and transmission rates and supports longer distances with lower loss than 62.5/125 fiber. This cable is fully compatible with multimode applications. The plenum rating provides the fire protection required to run this cable within walls and air plenums without using conduit. The patented injection molding process provides each connection greater durability in resisting pulls, strains and impacts from cabling installs. Each cable is 100% optically inspected and tested for insertion loss before you receive it. A pull-proof jacket design surrounds the popular 50/125 multimode fiber, immune to electrical interference.
