Single unit fiber optic plenum cables utilize buffered fiber designs for pulling and installation robustness. Contractors specializing in field connectorization favor these cables for two reasons. Individual colors on the buffered fibers help with identification, while the overall jacket diameter is kept as small as possible to facilitate installations around multiple bends, turns and corners. Cables with improved attenuation available and low smoke zero halogen available. Cables with extended 10 Gigabit Ethernet support distances available. The aramid fiber strength member provides plenty of installation strength for multi-floor pulls. Standard colors are yellow for single-mode, orange for multi-mode and teal for 10 gigabit. RoHS and REACH compliant.
