Optical Fibre Cable
Stranded Loose Tube Steel-Tape Armoured Cable
GYTS
Corrugated steel-tape armour · 2–288 fibres · duct and direct-buried
Same stranded loose-tube core as GYTA, but armoured with corrugated steel tape (PSP) instead of aluminium. Choose it where crush and rodent risk are the deciding factors — direct burial, rocky ground, industrial sites.
Key features
- Good mechanical and thermal performance
- Steel wire as the central strength member
- Hydrolysis resistant loose tube
- Tube filling compound ensures critical protection of fiber
- Specially designed stranded structure eliminating contraction of tubes
- Rugged, durable PE jacket protects against UV radiation, fungus etc.
- Crush resistance and flexibility
- Water-blocking measures : - Loose tube gel-filled - 100% cable filling compound - Corrugated steel tape(CST) enhancing moisture-proof

The fibers are positioned in a loose tube made of high modulus plastic and filled with gel. Tubes (and fillers) are stranded around the metallic strength member to form the cable core. The steel tape (CST) is longitudinally armored over the cable core, which is filled with water blocking compound. Finally a PE jacket is extruded.
