Product Description This is a black 1000 foot spool of indoor/outdoor plenum rated fiber optic distribution cable intended for large installations of short range runs at LAN Speeds. It is composed of 24 multimode fibers (62.5 micron core) inside a water blocking Aramid yarn wrapped in a black PVC outer jacket. Multimode fiber is optimized to work with fiber optic equipment using light wave lengths of 850nm (nanometers) or 1300nm. The cladding diameter is 125 microns.

The Graded-Step core and cladding of our black bulk 62.5/125 indoor/outdoor fiber optic cable is constructed using a high quality Corning InfiniCor 300 multimode fiber that is compliant with TIA/EIA 492AAAA-A, IEC 60793-2-10 and ISO/IEC 111801 (type OM1 fiber).

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, NFPA 262, of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP) for less toxicity during a fire.
