Bulk Fiber SM/04-Strand, OS1, 9/125, Mil-Tac — Black — PN 91-804520-0000K

Ruggedized single-mode OS1 9/125 4-strand “Mil-Tac” bulk fiber engineered for demanding indoor pathways and long pulls where conventional cable can be too fragile. Built with a fluoropolymer, flame-retardant plenum jacket and a helically stranded core, this design delivers high strength-to-weight performance, tight-bend survivability, and excellent mechanical protection—ideal for ducts, plenums, and air-handling spaces.

• Indoor-only plenum construction — flexible, flame-retardant jacketed design for air-handling spaces.
• High crush resistance — may reduce or eliminate the need for innerduct in many pathways.
• 900µm tight-buffered fibers — connectors can terminate directly to the fiber, reducing fanout kits and splice labor.
• Compact & pull-friendly — excellent strength-to-weight ratio for limited conduit space and tight bends.
• Helically stranded core — added flexibility and survivability in difficult installations.
• Armor option — can be ordered with interlocking armor as an alternative to conduit.
• UL Listed / NEC compliant — listed in accordance with NEC 770.179(A) for ducts, plenums, and air-handling spaces.
