In terms of structure, the 6-core optical cable is mainly divided into two types: outdoor and indoor. There are mainly two types of outdoor cores: central beam tube type and layer twist type. Generally, the layer twist type is more commonly used. It is believed that the layer twist type accommodates a larger number of cores, and the protection performance is better than that of the central beam tube type. (The central bundled tube type is a structure in which the optical fiber is located in the center of the optical cable and is filled with no paste and reinforced with double steel wires; the layered type is a structure in which the optical fiber surrounds the central strength member.) The indoor type mainly uses a bundle of The structure of the shape is mainly (the model is GJFJV)

6-core fiber optic cable transmission:

In terms of transmission, 6-core optical cables are mainly in single-mode and multi-mode specifications. Single-mode (inner diameter is 9μm, outer diameter is 125μm), multi-mode (there are two types, respectively, inner diameter is 62.5μm outer diameter is 125μm and inner diameter is 50μm outer diameter is 125μm), single mode is a long-distance transmission mode, wavelength It is 1310 and 1550; multimode is a short-distance transmission mode (the transmission distance is limited to within 2000 meters), and the wavelengths are 850 and 1300. (Single-mode is widely used now, and multi-mode is gradually being phased out)

6-core cable features:

The 6-core optical cable is a communication cable with the same transmission speed as light, and the bandwidth of the 6-core optical cable is

Wide, fast transmission, good confidentiality, anti-electromagnetic field interference, good insulation, long life, good chemical stability.

The commonly used models of 6-core optical cables are mainly divided into two types: GYXTW central beam tube type (armored) and GYXTY central beam tube type (non-armoured). The structure of GYXTW 6-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 6-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 material of the loose tube itself has good hydrolysis resistance and high strength, and the tube is filled with characteristic ointment to provide key sealing protection for the optical fiber.

2. The PE sheath has good anti-ultraviolet radiation performance, and the central reinforcing core of a single steel wire helps to parallel and stretch the optical cable.

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

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

5. The 6-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.

6. It is suitable for long-distance communication and inter-office communication.

7. Laying method: overhead, applicable temperature range: -40°C-+60°C, UL certified.

8. The more commonly used 6-core optical cable models: GYTA layered stranded optical cable, GYXTW central beam tube armored optical cable, GYTA53 double-sheathed stranded optical cable, GYTS armored layer
