GYFTC8S Steel Tape Armored Self-supporting Aerial FIG 8 Fiber Cable

GYFTC8S Steel Tape Armored Outdoor Self-supporting Figure 8 Aerial  Fiber Optic Cable

Description:

GYFTC8S fiber optic cable is a type of outdoor self-supporting aerial cable. Unique 8-shaped structure without additional steel messenger installation, which can effectively reduce the installation costs.  Small diameter and light weight, reducing the impact of wind and ice on the cable during operation. With non-metallic central strength member (FRP) and steel tape armored, designed for outdoor long-distance communication network with anti-rodent function.

Detailed Structure of GYFTC8S Aerial FIG8 Fiber Optic Cable:

• Fiber Unit：The 250μm optical fibers are placed into loose tubes made from high-modulus materials, and the inside of the loose tubes is filled with a waterproof compound, which plays a key protective role for the optical fibers.

• Central Strength Member：The center of the cable core is a non-metallic strength member. For some high cores like 144core, a layer of polyethylene (PE) is extruded on the strength member to reinforce the tensile strength.

• Cable Core：The loose tubes and filler ropes are stranded around the central strength member to form a compact circular cable core, and the gaps in the cable core are filled with a water-blocking filler to ensure good water-blocking performance.

• Sheath Structure：The cable core is longitudinally wrapped with a steel-plastic composite tape (PSP), and then a layer of polyethylene sheath is extruded in parallel with a galvanized or phosphated steel messenger to form a figure-8 structure.

Features:

• Figure-8 design: easy for self-supporting aerial installation, reducing installation costs.

• Good Mechanical Performance：The central strength member is made of non-metallic FRP (Fiber Reinforced Plastic), the messenger is made of corrosion-resistant phosphated steel wire; The figure-8 self-supporting structure features high tensile strength, and the longitudinally wrapped steel tape enhances the lateral pressure resistance of the optical cable, enabling it to withstand a certain degree of tensile and lateral pressure.

• Excellent Waterproof Performance：It has a full cross-section water-blocking structure. The loose tubes are filled with a special cable jelly, and the cable core gaps are filled with a water-blocking filler. The Corrugated Steel Tape improves the moisture penetration resistance of the optical cable, which can effectively prevent water from entering and protect the optical fibers.

• Stable Transmission Performance：High-quality optical fibers are selected, and the fiber excess length is precisely controlled, which ensures that the optical cable has excellent transmission, mechanical and temperature properties. It can work stably within the temperature range of -40°C to +70°C, which allows it to be used in various climatic conditions, from cold regions to hot and humid environmentsand, the service life can be more than 25 years.

Applications:

• Self-supporting aerial overhead fiber routes for telecom access, FTTH, FTTB, rural & suburban communication networks

• Aerial backhaul, community broadband, campus, park and mountain area fiber links

• Routes alongside power distribution lines (non-metallic core avoids EMI / lightning risk)

• Outdoor aerial access where rodent, rock fall or mechanical impact hazards exist (steel tape armor version preferred)

FAQs:

Q1: What is the typical span length?

Span depends on fiber count, messenger cross-section, wind & ice load, local overhead specification. Common span: 50–100 m. We can calculate and recommend messenger size according to your project conditions.

Q2: What messenger wire material is used?

Galvanized steel stranded messenger, integrated together with the optical unit in one figure‑8 HDPE sheath. No separate messenger or lashing wire needed.

Q3: Why add steel tape armor?

The corrugated steel tape armor provides anti-crush, anti-impact and anti-rodent protection. It is chosen for sites with rat bite risk, falling stones or frequent mechanical disturbance.

Q4: How about water blocking performance?

It adopts gel-filled loose tubes + water-blocking yarn/tape + longitudinally wrapped steel tape, with both radial and longitudinal water-blocking function, suitable for humid, rainy outdoor areas.
