This is a black 1,000ft black plenum 12 strand indoor/outdoor fiber optic cable intended for long distance runs at high speeds. It is composed of 12 singlemode fibers (9 micron core) inside a water blocking Aramid yarn wrapped in a black PVC outer jacket. Singlemode fiber is optimized to work with fiber optic equipment using light wave lengths of 1310nm (nanometers) or 1550nm. The cladding diameter is 125 microns.

The core and cladding of our black bulk indoor/outdoor 12 strand fiber optic cable is constructed using a high quality singlemode fiber that is ITU-T G.652.D compliant and backwards compatible with other legacy singlemode fibers.

This particular cable is Plenum Rated. Plenum spaces are the area between floors or above office areas for heating/cooling airflow. If an office were to catch fire, this plenum area could easily allow the spread of the fire to more floors or across the entire building. Plenum-rated cables are jacketed with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP) for less toxicity during a fire.
