Single-fiber optical cable uses a single tight‑buffered fiber of Φ900 μm or Φ600 μm as the optical transmission medium. It is covered with a layer of aramid yarn as the tensile strength member, and the outermost layer is extruded with a polyvinyl chloride (PVC) or low‑smoke, halogen‑free, flame‑retardant (LSZH) sheath.
• Uses tight‑buffered fiber for easy stripping and termination
• Tight‑buffered fiber has good flame‑retardant properties
• Aramid strength members provide excellent tensile performance for the cable
• Outer sheath features corrosion resistance, waterproofing, UV protection, flame retardancy, and environmental friendliness
• Used for optical fiber patch cords or pigtails
• Suitable for indoor riser and plenum cabling
• Temperature measurement of cables and busbars
