A standard roll of 24-core optical fiber cable is typically 1000 feet (approximately 305 meters).

Most commercially available 24-core fiber optic cables, whether indoor/outdoor or plenum-rated, are supplied on 1000-foot spools. For example, CableWholesale offers both black indoor/outdoor and yellow plenum 24-fiber singlemode cables in 1000-foot rolls, designed for long-distance high-speed transmission and compliant with ITU-T G.652.D and G.657.A1 standards (9/125 µm singlemode) for optimal performance at 1310nm and 1550nm wavelengths . For outdoor loose tube or ADSS (All Dielectric Self-Supporting) cables, lengths can vary depending on installation requirements, but standard rolls are often supplied in 100-meter increments or longer spools, with the exact length adjustable based on aerial span or duct installation needs .

Key Considerations

• Indoor/Outdoor Riser or Plenum Cables: Typically 1000 feet per spool, suitable for vertical risers, elevator shafts, or office plenum spaces.
• ADSS or Outdoor Loose Tube Cables: Supplied on drums, lengths may range from 100 meters to several hundred meters depending on project specifications.
• Custom Orders: Manufacturers can provide longer or shorter rolls to match specific deployment needs, especially for aerial or duct installations. In summary, for most standard applications, a 24-core optical fiber cable roll is 1000 feet, but specialized outdoor or aerial cables may come in shorter or custom lengths depending on installation requirements .
