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

Ruggedized single-mode OS2 9/125 12-strand distribution bulk fiber in a high-visibility yellow jacket, engineered for high-density backbone runs and demanding pathway pulls. Built with fluoropolymer, flame-retardant plenum materials and a helically stranded core, this cable delivers a compact, high strength-to-weight design for limited conduit space and tight bends—while preserving the low-loss performance OS2 is known for.

• OS2 single-mode (9/125) — optimized for long runs, backbone links, and low attenuation.
• 12-strand capacity — ideal for trunks between MDF/IDF closets, rack rows, and cross-connects.
• OFNP plenum-rated — suitable for air-handling/plenum spaces and strict indoor code requirements.
• Indoor/Outdoor distribution build — designed for conduit pulls and protected exterior routing segments.
• 900µm tight-buffered fibers — connectors can terminate directly to the fiber, reducing fanout kits and splice labor.
• High crush resistance — may reduce or eliminate the need for innerduct in many pathways.
• Helically stranded core — improved flexibility and survivability in difficult pulls and tight bends.
• Armor option — 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.
