Direct Buried Single Armor Double Jacket Fiber Optic Cable GYTY53

Description

The Direct Buried Single Armor Double Jacket Fiber Optic Cable GYTY53 is an outdoor fiber optic cable designed for direct burial applications. It features a single armor layer and double jacket construction, providing mechanical protection and durability for underground installations. This cable is commonly used for long-distance communication links and installations where the cable needs to be buried directly in the ground without the need for additional ducts or conduits. The fibers, 250μm, 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. After the PSP is longitudinally applied over the inner sheath, the cable is completed with a PE outer sheath.

Structure

Characteristics

 The following measures are taken to ensure the cable watertight:     

• Steel wire used as the central strength member
• Loose tube filling compound
• 100% cable core filling
• PSP enhancing moisture-proof
• Water-blocking material

 Standard

 Standard YD/T 1155-2001 as well as IEC 60794-1.
