24 48 96 144 Core Optical Fiber Cable GYTS53 Double Armored and Double Sheathed Stranded Outdoor Underground Fiber Optic Cable

GYTS53 fiber optic cable is a double-armored, double-sheathed outdoor communication optical cable with excellent mechanical protection and waterproof capabilities. It is suitable for harsh environments such as direct burial, pipelines, and tunnels.

1.Cable Description

The fibers, are positioned in a loose tube made of a high modulus plastic. The tubes are filled with a water-resistant filling compound. A steel wire, sometimes sheathed with polyethylene (PE) for cable with high fiber count, locates in the center of core as a metallic strength member. Tubes (and fillers) are stranded around the strength member into a compact and circular cable core. The cable core is filled with the filling compound to protect it from water ingress, over which a thin PE inner sheath is applied. With two Corrugated steel tape member and a PE outer sheath.

3.  Application

 *  Adopted to ourdoor distribution;

 *  Suitable for aerial, duct and direct buried;

 *  Long distance and local area network communication.

4.  Characteristics

 *  Good mechanical and temperature performance

 *  High strength loose tube that is hydrolysis resistant

 *  Special tube filling compound ensure a critical protection of fiber

 *  Crush resistance and flexibility

 *  The following measures are taken to ensure the cable watertight:

 *  Steel wire used as the central strength member

 *  Loose tube filling compound and 100% cable core filling

 *  PSP enhancing moisture-proof

 *  Water-blocking material

5. Features:

* High Mechanical Strength: The steel tape armor provides excellent resistance to pressure and impact, making it suitable for direct burial and pipeline installation.

* Waterproof and Moisture-Proof: The loose tube is filled with grease, water-blocking tape, and double-layered sheathing, providing superior waterproofing.

* Corrosion Resistance: The PE sheathing and plastic-coated steel tape are suitable for acidic, alkaline soils and humid environments.

* Rodent and Ant Repellent: The steel tape armor effectively prevents damage from rodents.

* Temperature Adaptability: The operating temperature is typically -40°C to +70°C.

5.2 Cable construction details

6.Cable Mechanical characteristic

GYTS53 fiber optic cable, with its steel tape armor + double-layer sheath design, performs outstandingly in terms of pressure resistance, waterproofness, and resistance to rodents and ants, making it an ideal choice for harsh environments such as direct burial and pipelines. If higher tensile strength is required (such as in overhead applications), consider GYDXTW (steel wire armor) or GYTA53 (aluminum tape armor).
