Gydts optical cable is

GYDTS optical cable is a ribbon-type, loose-tube fiber optic cable with corrugated steel tape armoring, designed for high-density, outdoor installations in aerial, duct, or direct-buried environments.

Structure and Design

GYDTS cables consist of 4, 6, 8, 12, or more fiber ribbons placed inside a loose tube made of high-modulus material, which is filled with a water-blocking gel to prevent moisture ingress . A central metal strength member provides structural support, while the loose tube and optional filler ropes are helically stranded around it to form a compact, circular cable core . The cable is further reinforced with double-sided corrugated steel tape (PSP) and encased in a polyethylene (PE) sheath, offering excellent mechanical protection and environmental resistance .

Key Features

• High fiber density: Ribbon configuration allows mass fusion splicing of multiple fibers simultaneously, improving installation efficiency .
• Waterproof and moisture-resistant: Loose tube filled with thixotropic gel and water-blocking fillers ensure reliable performance in wet conditions .
• Mechanical strength: Corrugated steel tape armoring enhances crush resistance, rodent protection, and overall durability .
• Flexibility and ease of installation: Loose tube design allows easy drawing, splicing, and cleaning, reducing installation costs .
• Standards compliance: GYDTS cables meet YD/T 981.3-2009 and IEC 60794-1 standards for optical fiber ribbon cables .

Applications

GYDTS optical cables are suitable for aerial, duct, and direct-buried installations, particularly in high-density networks such as metropolitan area networks (MANs), backbone networks, and fiber-to-the-home (FTTH) or fiber-to-the-building (FTTB) deployments . Their design supports long-distance transmission and high-speed data transfer, making them ideal for modern telecommunications infrastructure.

Advantages

• Low attenuation and dispersion for reliable signal transmission .
• Accurate geometric dimensions of fiber ribbons for efficient splicing .
• Excellent temperature stability and flame retardancy .
• Customizable fiber counts and armoring options to meet specific project requirements . In summary, GYDTS optical cable combines high-density ribbon fibers, loose-tube flexibility, and armored protection, making it a robust solution for outdoor and high-capacity fiber optic networks.
