Bulk Fiber SM/12-Strand, OS2, 9/125, OFNP, Indoor (Distribution) — Yellow

Ruggedized single-mode OS2 9/125 12-strand distribution bulk fiber in a high-visibility yellow jacket, engineered specifically for indoor plenum pathways where high density, low loss, and long-pull survivability matter. Built with fluoropolymer, flame-retardant plenum materials and a helically stranded core, this compact design fits limited conduit space, handles tight bends, and protects fibers during demanding installs—while delivering the long-distance performance OS2 is known for.

• OS2 single-mode (9/125) — optimized for long runs, backbone links, and low attenuation.
• 12-strand capacity — ideal for high-density trunks between MDF/IDF closets, rack rows, and cross-connects.
• OFNP plenum-rated — suitable for ducts, plenums, and air-handling spaces with strict indoor code requirements.
• Compact, pull-friendly design — high strength-to-weight ratio for limited conduit space and long, tight-bend pulls.
• Helically stranded core — improved flexibility, mechanical protection, and survivability in difficult installations.
• 900µm tight-buffered fibers — terminate connectors directly to the fiber, reducing fanout kits and splice labor.
• High crush resistance — may reduce or eliminate the need for innerduct in many pathways.
• Armor option available — can be ordered with interlocking armor as an alternative to conduit installation.
• UL Listed / NEC compliant — listed in accordance with NEC 770.179(A) for use in ducts, plenums, and air-handling spaces.
