Freeform Ribbon™ Indoor RoHS Riser Cable – 1728F

RPRC - High Count

Sumitomo Electric Lightwave’s Freeform Ribbon™ Indoor Riser Rated cables feature a flame retardant outer jacket and 250μm color-coded optical fibers for easy fiber identification. The Freeform Ribbon™ is splice compatible with conventional ribbon and a smaller cable diameter – increasing density resulting in smaller cable outside diameter. Flexible dielectric strength members provide mechanical durability within a flame retardant jacket and the non-preferential bend axis allows for easy installation in space-constrained areas. The Cables meets UL 1666 and CSA FT4  specifications.




  • Dry Central Tube Design for Easy Installation; No Mess When Splicing
  • Pliable Ribbon Technology allows higher fiber density in small duct spaces
  • 12 Fiber Ribbon Groupings For Ease and Compatibility with Multi-Fiber Connectors
  • Color-Coded Optical Fibers for Quick and Easy Identification
  • RoHS Compliant
