Does YJ optical cable contain PVC

Fiber optic splice closure knowledge brief Published 07 Mar 2023

Prepared for preliminary research by the RIVO OPTICAL knowledge desk. Confirm cable count, splice capacity, sealing class, tray layout, protection sleeves and installation requirements against current standards and product documentation.

Yes, YJ optical cables typically have a PVC outer sheath.

YJ optical cables, such as the GJFJV indoor fiber optic cables, are constructed with multiple layers for protection and strength. The optical fibers themselves are coated with protective materials, often including aramid yarn for reinforcement, and then encased in an outer sheath made of PVC (polyvinyl chloride), which provides flame retardancy, chemical resistance, and mechanical protection for indoor applications .

Key Features of YJ Optical Cables
  • Insulation and Sheath: The fibers are individually coated and then bundled with a PVC outer jacket, which is flame-retardant and abrasion-resistant .
  • Strength Members: Aramid yarn or similar materials are used to provide tensile strength and prevent fiber breakage.
  • Applications: These cables are suitable for indoor distribution, tunnels, and light-duty outdoor use when combined with PE tubes. They are non-conductive and resistant to electromagnetic interference .
  • Safety: PVC sheathing ensures the cable meets fire safety standards and provides durability in typical installation environments.
Summary

In short, YJ optical cables do contain PVC, primarily in the outer sheath, while the core optical fibers are protected by other materials like aramid yarn and buffer coatings. This combination ensures both mechanical protection and compliance with safety standards for indoor and controlled outdoor environments .
