GYFTC8Y Self-support Non-Armored Figure 8 Aerial Fiber Optic Cable

GYFTC8Y Non-Armored Self-supporting Aerial FIG8 Fiber Optic Cable 

Description:

GYFTC8Y is an outdoor loose-tube figure-8 self-supporting aerial fiber optic cable without metal armor layer, specially designed for overhead pole-mounted deployment.

Its unique integrated figure-8 profile combines an independent galvanized steel stranded messenger (top circular section) and fiber optic core unit (bottom circular section), connected by a unified PE web. The whole cable is extruded with one-piece black PE outer sheath.

The cable adopts central FRP non-metallic strength member + multi-loose-tube stranded core structure, fully water-blocked design, no steel/aluminum armor tape inside, lightweight and cost-effective. It eliminates the need for separate supporting steel strand during aerial laying, realizing one-step self-support installation for medium-short overhead spans (max 100–150m).

Features of GYFTC8Y Non-Armored Aerial FIG8 Cable:

• Integrated self-support figure-8 structure
  Built-in galvanized steel messenger eliminates separate supporting strands, speeding up aerial installation and cutting labor costs significantly.
• Lightweight non-armored design
  No metal armor tape reduces cable weight, lessens load on utility poles and lowers transport & laying expenses.
• Reliable mechanical performance
  High tensile strength fits overhead spans of 80–150 m; sufficient fiber excess length prevents extra attenuation under tension, bending or crushing.
• Full water-blocking construction
  Jelly-filled loose tubes, cable filling compound and optional water-swellable tape deliver superior longitudinal waterproof performance for outdoor use.
• Strong environmental adaptability
  UV-resistant black HDPE outer sheath works steadily at -40℃ ~ +70℃, resisting sunlight, rain, frost and outdoor aging.
• Lower lightning induction risk
  Absence of steel armor reduces induced lightning hazards, suitable for areas with mild lightning activity.

FAQs:

Q1: What is the maximum overhead span of GYFTC8Y?

Standard applicable span ranges from 80 m to 150 m. It is not recommended for spans over 150 m or regions with heavy ice, strong wind and frequent thunderstorms; ADSS cable is a better choice for long-span scenarios.

Q2: Does GYFTC8Y contain metal armor? Will it be easily struck by lightning?

There is no steel/aluminum armor layer inside the optical core, which reduces lightning induction risk compared with armored figure-8 cables. However, the messenger wire is galvanized steel; grounding treatment is still required in thunder-prone areas.

Q3: Can it be laid underground or pipeline?

Not recommended. It is specially designed for aerial overhead deployment;

Q4: What are the main advantages over armored figure 8 cables?

Lighter weight, lower pole load, lower raw material and transportation cost, faster stripping operation, simpler construction and lower lightning induction risk.
