This is a 9.0m (29.5ft) LC (male) to SC (male) aqua OM4 duplex 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. 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. Our patch cables are 100% compliant for all of your networking needs and are guaranteed by federal law to not affect or void OEM warranties.
