Optical Fibre Cable
Figure-8 Self-Supporting Aerial Cable
GYTC8S
Integral steel messenger · no separate lashing · 2–144 fibres
A figure-8 profile with the steel messenger built into the sheath, so the cable goes up in one pass — no separate messenger, no lashing crew. On short and medium pole spans this is usually the cheapest aerial route once labour is counted.
Key features
- Figure-8 design, easy for self-supporting aerial installation, reducing installation costs
- Small size, light weight and soft, easy for installation
- Hydrolysis resistant loose tube
- Tube gel ensures critical protection of fiber
- Corrugated steel tape(CST) enhancing moisture-proof

The fibers are positioned in loose tubes that are made of high-modulus plastic and filled with tube gel. The tubes (and fillers) are stranded around a metallic central strength member to form a cable core.The core is filled with water-blocking compound and armored with corrugated steel tape(CST). Stranded steel wires are applied as the messenger. Finally, a figure-8 PE outer jacket is extruded.
