The commonly used models of 4-core optical cables are mainly divided into two types: GYXTW central tube type (armoured) and GYXTY central tube type (non-armoured). The structure of GYXTW 4-core optical cable is to put 250μm optical fiber into a loose tube made of high modulus material, and the loose tube is filled with waterproof compound. The loose tube is longitudinally wrapped with a layer of double-sided plastic-coated steel tape (PSP), and a water-blocking material is added between the steel tape and the loose tube to ensure the compactness and longitudinal water-blocking of the optical cable. Vinyl sheathed cable. The structure of the GYXTY 4-core optical cable is that the 250μm optical fiber is sheathed in a loose tube made of high-modulus material, and the loose tube is filled with a waterproof compound. A layer of water blocking layer is attached to the outside of the loose tube, and two parallel steel wires are placed on both sides to extrude a polyethylene sheath into a cable.

1. The loose tube material itself has good hydrolysis resistance and high strength

2. The special ointment is filled in the tube, which provides key sealing protection for the optical fiber

3. PE sheath has good anti-ultraviolet radiation performance

4. The central reinforcing core of a single steel wire contributes to the parallel and stretching of the optical cable

5. Anti-stretching, wear-resistant, impact-resistant, crush-resistant, can be repeatedly bent, twisted, bent, curved (bending angle not exceeding 90°), gunshot, etc., with good mechanical properties and temperature characteristics

6. Double-sided corrugated steel tape (PSP) improves the moisture resistance of the optical cable

7. The 4-core optical cable has the advantages of fast transmission speed and long distance, good confidentiality, anti-electromagnetic field interference, good insulation, good chemical stability, long life, low loss, and has good characteristics and economic benefits.

8. Suitable for long-distance communication and inter-office communication

9. Laying method: overhead

10. Applicable temperature range: -40℃-+60℃

11. The UL certified GYXTW 4-core optical cable and GYXTY 4-core optical cable are aerially laid optical cables, in addition to direct buried optical cables and pipeline optical cables (GYTS, GYTA, GYTY53, GYTA53)
