What is the gyty cable ?

I. GYTY Cable Overview

Definition and uses

GYTY cable is a fiber optic cable with loose tube structure, widely used in the construction of communication networks. Due to its design features, GYTY cable is mainly used for long distance communications and local area networks (LAN). It is particularly suitable for outdoor aerial installation or in ducts.

Structure of GYTY cable

GYTY cable structure features a loose central tube, optical fibers, steel wire reinforcement (according to needs), and an outer polyethylene sheath (PE).

The main components of the GYTY cable structure are as follows: :

Optical fibers

GYTY cable can contain single mode or multimode optical fibers, depending on the needs of the application. The optical fibers are placed in a loose tube filled with gel, which serves to protect against humidity and absorb shock.

Loose tube

The optical fibers are placed in a loose tube filled with gel. The loose tube is usually made of plastic material. The gel prevents water infiltration and provides some protection against shock.

Central reinforcing element

The central reinforcing element of GYTY cable is generally a metallic steel wire (often made of phosphated steel). This reinforcing element increases the tensile strength of the cable and is the main load-bearing component. In addition to ensuring stability optical fibers, it provides sufficient mechanical resistance and good adaptability to the environment.

Water Blocking Materials

Between the loose tube and the central reinforcing element, Water blocking wires or strips are used to further prevent water from entering the inside of the cable.

Outer sheath

The outer sheath of GYTY cable is generally made of polyethylene (PE), which offers good resistance to wear, to corrosion and ultraviolet rays. The outer sheath protects the internal structure of the cable against attacks from the external environment.

II. Main features of GYTY cable

1. High sustainability

GYTY cable uses high strength loose tube materials, offering high tensile and pressure resistance, which makes it possible to resist the influences of the external environment. The materials of its outer sheath have good corrosion resistance properties, which allows the cable to adapt to various harsh climatic conditions.

2. High density and low loss

GYTY cable can support a large number of optical fibers, making it very suitable for high capacity communication needs. The low attenuation coefficient of the cable ensures stable signal transmission and good performance over long distances, making it an ideal choice for long distance communications.

3. Ease of installation and maintenance

Loose tube design allows optical fibers to have good flexibility, thus facilitating installation and adaptation to various complex terrains. The relatively simple structure of GYTY cable facilitates its maintenance, effectively reducing operation and maintenance costs.

III. Applications of GYTY cable

1. Communication longue distance

Thanks to its low loss, GYTY cable is very suitable for long distance communication applications. It ensures stable and reliable signal transmission in long distance communication lines, rural communications and other remote connections.

2. Optical fiber to the home (FTTH) and optical fiber to the building (FTTB)  

In fiber optic projects to the home (FTTH) and up to the building (FTTB), GYTY cable is widely used. It can meet high bandwidth needs, providing users with fast and stable broadband access.

3. Corporate and campus networks

GYTY cable is suitable for enterprise and campus networks, capable of meeting the needs of large data and high performance transmission, providing strong support for internal communication and data transmission.

IV. GYTY Cable Types

GYTY cable

GYTY cable is suitable for outdoor environments such as overhead installation and conduit installation. It has tensile and corrosion resistance characteristics, making it suitable for communication lines in general conditions.

GYTY53 cable

An improved version of the GYTY cable, with double sheath and steel strip armor, making it more suitable for environments requiring increased mechanical protection, such as direct burial underground or other complex environments.

Gyfty cable

Uses an FRP (non-metallic reinforcing element) instead of steel wire armor, making it suitable for situations requiring an all-dielectric structure to avoid electromagnetic interference, typically used in specific industrial environments and electrical installations.

V. Comparison between GYTY and GYTY53 cables

Structural differences

GYTY53 cable adds double sheath and double steel strip armor compared to GYTY cable, significantly enhancing the cable's resistance to compression and external interference. On the other hand, the structure of the GYTY cable is simpler and better suited to aerial exterior applications or installation in more traditional conduits.

Application differences

Due to its reinforced mechanical protection, GYTY53 cable is more suitable for direct burial underground or environments requiring additional protection. The GYTY cable, as for him, is best suited to overhead installation and relatively simple conduit laying situations.

VI. Disadvantages of GYTY cable

Sensitivity to environmental conditions

In extreme cold or high temperature conditions, GYTY cable performance may be affected. In such cases, additional protective measures are needed to deal with mechanical damage and environmental impacts.

High installation requirements

Installation of GYTY cable requires specialized equipment and technical support, which increases the requirements for laying and connection, and may result in higher initial installation costs.
