Armored Plenum 6-Strand OS2 9/125 Singlemode Fiber Cable — Corning SMF-28 Ultra, Yellow Spool, 500 foot

Designed for demanding indoor installations, this 6-strand OS2 (9/125) singlemode distribution cable comes on a 500 foot yellow spool. A spiral steel armor jacket protects the cable from impact and mechanical stresses, improving durability in harsh or high-traffic environments. Inside are six Corning SMF-28 Ultra singlemode fibers, engineered for low attenuation at 1310nm and 1550nm to support reliable, long-reach network performance. The plenum-rated yellow outer jacket allows safe installation in air plenums and other spaces that require higher fire-safety standards.
