Direct-buried Armoured Optical Cable

Product Description

Direct-buried Armoured Optical Cable is a heavy-duty underground optical transmission solution specially engineered for direct burial without extra duct protection. It comes with two optimized structures: GYTA53 double-armor double-jacket and GYTS53 PSP corrugated steel tape armor, both built with rugged mechanical design and full-section water-blocking system. Adopting stranded loose tube structure and G.652D single-mode fiber, it provides all-round protection against crush, impact, rodent gnawing, moisture and soil corrosion. With wide temperature adaptability and ultra-low attenuation, it delivers stable long-haul transmission for harsh underground environments including high groundwater areas, wetlands, rocky and saline-alkali regions, serving as a reliable backbone for telecom and inter-office communication networks.

Key Features

1.Dual Armor Options Available: GYTA53 double-armor double-jacket / GYTS53 PSP armor, customizable for different geological conditions

2.All-round Mechanical Protection: Outstanding crush & impact resistance, defends against soil pressure, rock extrusion and rodent damage

3.Full-section Water-blocking: Multi-layer moisture isolation, perfectly adapts to high groundwater and humid underground environments

4.Anti-corrosion & Anti-aging: Durable PE/LSZH jacket resists soil corrosion, UV and long-term outdoor aging

5.Ultra-low Attenuation: G.652D fiber ensures ≤0.22dB/km@1550nm for stable long-distance transmission

6.Wide Temperature Resistance: Operates stably at -40℃~+70℃, adapts to extreme climate changes

7.High Tensile Strength: Reliable strength member withstands installation tension and ground subsidence stress

8.Cost-effective Deployment: Direct burial without conduits, greatly reduces construction period and project cost
