This is a 1000-foot spool ofzip cord fiber optic cable - Aqua, designed specifically for largeinstallations that require terminations. The cable is made of multimode fiberand has a 50-micron core, enabling it to transmit data at 10 Gigabit speedsover short distances. Multimode fiber works best with fiber optic equipmentthat uses light wavelengths of either 850nm or 1300nm. The cord is duplex,meaning it allows for synchronous communication between devices. The cable iscompliant with standards and has a superior OFNP (plenum) safety fire ratingthat meets UL 910 regulations, replacing OFNR (riser) rated cable.
