Product Description This is a black 2000-foot spool of indoor/outdoor-rated fiber optic distribution cable intended for long-distance runs at high speeds. It is composed of 12 single-mode fibers (9-micron core) inside a water-blocking Aramid yarn, wrapped in a black PVC outer jacket. Single-mode fiber is optimized to work with fiber optic equipment using light wavelengths of 1310nm (nanometers) or 1550nm. The cladding diameter is 125 microns.

The core and cladding of our black bulk indoor/outdoor fiber optic cable is constructed using a high-quality YOFC singlemode fiber that is ITU-T G.657.A1 compliant and backwards compatible with other legacy singlemode fibers.

This particular cable is Riser-Rated (CMR), meaning it complies with UL 1666. It is for usage in vertical tray applications without environmental air. Examples being: cable runs between floors through cable risers or in elevator shafts. These cables self-extinguish, preventing the flame from traveling up the cable in a vertical burn test. This fiber optic cable is solidly constructed, UL-rated, and RoHS-compliant.
