ADSS Fiber Optic Cable

Rodent Repellency

Flat FRP Bite Repellent: Made of glass fiber cross-linked with resin. Glass fiber is thin and brittle, and can injure a rodent's mouth when chewed. The resin cross-linking increases the fiber's stiffness and density, resulting in superior rodent repellency and effective resistance to rodent bites.

Glass Yarn Bite Repellent: Less effective. Due to its small diameter and lack of rigidity, glass yarn fibers easily become entangled with the sheathing material when chewed, resulting in less damage to the rodent's mouth.

Mechanical Properties

Flat FRP Bite Repellent: Features high tensile strength (≥1200 MPa) and elastic modulus (≥50 GPa), enhancing the cable's tensile strength and self-supporting capacity, making it an ideal self-supporting tensile component.

Glass Yarn Bite Repellent: Lacks self-supporting capacity, resulting in reduced tensile strength if the outer sheath is damaged, and offers no protection against rodent punctures.

Construction Difficulty

Flat FRP Bite Repellent: The production process is complex, the cable is relatively rigid, bending is difficult, and splicing the FRP tape is time-consuming.

Glass yarn bite protection: Installation can cause injuries, and the winding and securing of glass yarn is complex. A large amount of glass yarn is required to achieve rodent-proofing, increasing the difficulty of installation.

Cost

Flat FRP bite protection: Due to the complex materials and production process, the cost is relatively high.

Glass yarn bite protection: Although the cost of a single piece of glass yarn is relatively low, it requires large quantities, and the production process increases costs, making the overall cost high.

Environmental Protection

Flat FRP bite protection: The resin cross-linking process reduces the problem of loose glass fibers, making it more environmentally friendly.

Glass yarn bite protection: Loose glass fibers are prone to scattering, potentially affecting the environment and human health, making it less environmentally friendly.

Ultra-small & lightweight

With a 6.6–8.2 mm outer diameter and 45–65 kg/km weight, it lowers wind load and fits tight pole routes for fast upgrades.

One model, broad coverage

Supports 2–288 fibers and 80–400 m spans, simplifying procurement and reducing total cost across access, backhaul, and metro builds.

Long-span reliability

Dual jackets and aramid reinforcement deliver 3.2–4.5 kN rated tensile strength for stable 200–300 m spans, including high-voltage corridors.

Dielectric with rodent defense

Flat FRP (fiber-reinforced plastic) armor provides up to 3000 N/100 mm crush resistance and 2.5/5.0 kN tensile for durable roadside and rural deployment.
