GYFTC8F is an all-dielectric, non-armored, loose tube stranded figure-8 self-supporting aerial fiber optic cable.
Model Definition:
GY: Outdoor communication optical cable
F: Fully non-metallic (all FRP, no steel components)
T: Loose tube stranded gel-filled
C: Self-supporting aerial type
8: Figure-8 cross-section profile
F: FRP solid rod as integrated messenger wire, no metal armor
The cable adopts an integrated figure-8 co-extruded sheath, consisting of two parallel circular sections connected by a thin PE web:
Lower large circle: Optical transmission core with central FRP strength member;
Upper small circle: Independent solid FRP messenger rod as the full load-bearing component for aerial spanning.
No steel tape, aluminum tape or metal armor inside the cable, achieving complete non-metallic design to eliminate electromagnetic induction risks. Fiber count ranges from 2 to 144 cores, compatible with G.652D, G.657A1/A2 single-mode fibers for FTTx, access network aerial deployment near high-voltage power lines.
| Layer | Composition |
| 1. Optical Fiber | 250μm color-coded single-mode optical fibers, low attenuation, low bending loss, standard color identification for easy splicing and core management. |
| 2. PBT Loose Tube Gel-filled | High-modulus PBT loose tubes house optical fibers; each tube holds 6–12 fibers. Special thixotropic water-blocking jelly fills tubes to isolate fibers from moisture, buffer mechanical shock and stabilize transmission performance under wide temperature ranges. |
| 3. Central FRP Strength Member | Solid glass fiber reinforced plastic rod at cable core center, provides radial crush resistance and secondary tensile protection for the fiber unit, fully non-conductive. |
| 4. Cable Core Water-Blocking System | Loose tubes and plastic filler rods are stranded around central FRP into a compact circular core; gaps fully filled with water-blocking yarn and jelly, realizing full-section longitudinal & radial waterproofing to prevent water penetration along the cable length. |
| 5. Connecting Web | Thin integrated PE strip linking the fiber core section and FRP messenger section; designed for easy tearing during cable termination to separate messenger and fiber units without damaging optical cores. |
| 6. FRP Messenger Rod | Solid high-tensile FRP rod in the upper figure-8 circular chamber, the primary load-bearing component to support cable self-weight, wind and ice loads during aerial installation; zero metal avoids EMI and lightning induction. |
7. Single PE Outer Sheath (Non-Armored) | HDPE black sheath co-extruded to wrap both fiber core and FRP messenger as one integrated figure-8 profile. No metal armor layer, lightweight, UV-resistant, anti-aging for outdoor overhead exposure. |
Structure layer sequence (from inner to outer):
Optical Fiber → Water-blocking Jelly → PBT Loose Tube → Central FRP Strength Member → Filler Rod + Core Water-blocking Compound → Integrated PE Web → FRP Messenger Rod → Co-extruded FIG8 Outer Sheath
All-Dielectric Anti-EMI & Anti-Lightning
Integrated Self-Supporting Figure-8 Design
Non-Armored Lightweight & Flexible
Superior Waterproof & Temperature Adaptability
Stable Mechanical Performance
Low Maintenance & Long Service Life over 25 years
Rural villages, suburban residential areas, shantytowns and building-to-building overhead fiber drops, replacing metal messenger figure-8 cables for EMI-sensitive zones.
Parallel laying with power transmission overhead wires; fully non-metallic design avoids induced electricity risks, the core advantage over steel-strand figure-8 cables (GYTC8S/GYFTC8Y).
Pole-to-tower short-span aerial fiber for 5G micro base station signal backhaul, lightweight for fast mass deployment.
4. Strong Electromagnetic Interference Industrial Zones
Factories, transformer stations, railway power supply corridors and electrified railway overhead communication links where metal optical cables suffer EMI interference.
GYFTC8F: All FRP messenger, zero metal, anti-lightning & anti-EMI, lightweight;
GYTC8S: Steel strand messenger, conductive, cannot be laid near high-voltage power lines, heavier weight.
No. The messenger rod and core strength member are both solid FRP; no steel tape, aluminum tape, steel strand or metal armor. It is a full dielectric cable.
FRP is non-conductive to avoid induced current and lightning damage when installed parallel to power lines; FRP will not rust in coastal/salty environments, lighter weight reduces pole load.
Standard safe span up to 100 meters under normal wind and light ice load. For heavy ice areas, ADSS cable is recommended instead.
Yes. Custom fiber counts, special low-friction sheath, high UV-resistant sheath, color-marked sheath and customized FRP tensile strength are acceptable.
