Corning 12-strand OS2 9/125 singlemode fiber on a 2000-foot spool, built for mixed indoor and outdoor plenum installations. The fiber meets ITU-T G.652.D specifications and remains backward compatible with earlier singlemode types for broad interoperability. Safety-focused construction includes a plenum rating suitable for building air spaces and a low-smoke PVC or FEP outer jacket to limit smoke/toxic gas emission and reduce flame spread. A water-blocking Aramid yarn core provides moisture resistance and added tensile strength, ensuring dependable performance in a variety of installation environments.
