    • Insulating material: A layer of insulating material is wrapped around the optical fiber, usually a non-metallic high-strength polymer, such as flame-retardant polyethylene (FRP) or flame-retardant polyamide (ARAMID).
    • Outer sheath: There is a protective sheath on the outside of the optical cable, usually made of polyethylene (PE) or other weather-resistant materials, to protect the optical cable from damage from the external environment.
  3. Transmission performance and technical indicators: The transmission performance and technical indicators of ADSS optical cable include:

    • Transmission rate: ADSS optical cable can support different transmission rates, such as 1Gbps, 10Gbps, 40Gbps or higher, depending on the fiber type and equipment used.
