Product Description

Central Bundle Tube Fiber Optic Cable (GYXTW).

Product Description:

1. Optical fiber

2. Fiber paste: water-blocking compound

3. Loose tube: thermoplastic material

4. Reinforcements: two parallel phosphating steel wires

5. Water-blocking material: water-blocking filler

6. Armor layer: steel-plastic composite belt

7. Outer sheath: black polyethylene

Single-mode or multimode fibers are sleeved into a loose tube made of high-modulus polyester material, which is filled with a water-repellent compound. The loose tube is longitudinally wrapped with a layer of double-sided chrome-plated plastic-coated steel tape, and a water-blocking material is added between the steel belt and the loose tube to ensure the compactness and longitudinal water resistance of the optical cable, and two parallel steel wires are placed on both sides and then extruded into a polyethylene (PE) sheath to form a cable.

Features and applications

● Good compressive resistance;

● Small diameter, light weight, easy to lay;

● Pipeline installation, overhead installation, direct burial installation.

● Double-sided chrome-plated plastic-coated steel tape (PSP) improves the moisture permeability of the optical cable.

● Two parallel steel wires ensure the tensile strength of the optical cable.

●Specially designed tight optical cable structure, effectively place the casing retracted.
