This is a 2.0m (6.6ft) SC (male) to SC (male) green OM4 duplex OFNP (Plenum-rated) patch straight cable that is used for high speed data transfer. An OM4 cable has a core size of 50m microns that supports 10 Gigabit Ethernet at lengths measuring up to 550 meters , and 100 Gigabit Ethernet measuring up to 150 meters and is reverse compatible with OM3. OFNP (Plenum-rated) cables must self-extinguish and prevent re-ignition. Duplex cabling provides two-strands of fiber and is most commonly used in applications that utilize one lane to transmit and one lane to receive.
