How to understand the longitudinal water-blocking wall of central tube non-metallic non-armored optical cable?

The water-blocking material layer plays a vital role in GYFXY optical cable. Its main function is to enhance the longitudinal water-blocking ability of the optical cable, that is, to prevent moisture from penetrating into the interior from tiny gaps or damages in the optical cable. This layer of water-blocking material usually uses high-performance water-blocking grease or water-blocking tape, which has excellent waterproof performance and viscosity, and can fit tightly on the outer surface of the loose tube of the optical cable to form an indestructible waterproof barrier.

In the production process of optical cables, although manufacturers will take various measures to ensure the quality of optical cables, minor defects are still difficult to completely avoid. These defects may include tiny gaps between the loose tube and the sheath, and tiny movements or damages of the optical fiber in the loose tube. These seemingly insignificant defects may become channels for penetration once they encounter moisture, causing damage to the optical fiber inside the optical cable, thereby affecting the transmission performance.

The existence of the water-blocking material layer is like a solid Great Wall, which firmly blocks these potential penetration channels. It can effectively prevent moisture from penetrating into the interior through the tiny gaps or damaged parts of the optical cable, thereby protecting the optical fiber inside the optical cable from moisture erosion. This design not only improves the waterproof performance of the optical cable, but also extends the service life of the optical cable, ensuring the stable operation of the optical cable in various environments.

The reason why the water-blocking material layer can play such an important role in the unitube non-metallic non-armored cable(GYFXY)optical cable is mainly due to its unique performance characteristics.

The water-blocking material has excellent waterproof performance. It can maintain a stable waterproof effect under various humidity and temperature conditions to ensure that the optical cable is not corroded by moisture. This performance feature enables the optical cable to maintain stable working performance in a humid or underwater environment.

The water-blocking material has good viscosity and elasticity. It can fit tightly on the outer surface of the loose tube of the optical cable to form a continuous waterproof barrier. When the optical cable is bent or stretched, the water-blocking material layer can also maintain a certain elasticity to ensure that it will not break or fall off due to the deformation of the optical cable.

The water-blocking material layer also has good hydrolysis resistance and chemical stability. It can resist the erosion of various chemicals and microorganisms, ensuring that the optical cable will not fail due to chemical corrosion during long-term use.

The application value of the water-blocking material layer in GYFXY optical cable cannot be underestimated. It not only improves the waterproof performance of the optical cable, but also ensures the stable operation of the optical cable in various environments. This design makes the optical cable widely used in telecommunications, radio and television, data communications and other fields.

In the field of telecommunications, GYFXY optical cable has become an important part of long-distance communication, urban communication and mobile communication networks with its excellent waterproof performance and stable working environment. It can ensure the stable transmission of communication signals and improve the reliability and stability of communication networks.

In the field of radio and television, the waterproof performance of GYFXY optical cable has also won it a wide range of applications. It can ensure the stable transmission of radio and television signals and improve the audience's viewing experience. The lightness and easy laying characteristics of the optical cable also make the construction of radio and television networks more convenient and efficient.

In the field of data communications, GYFXY optical cable also plays an important role. It can support high-speed data transmission and meet the needs of new services such as big data and cloud computing. The waterproof performance and stable working environment of the optical cable also provide strong guarantees for its application in data centers, cloud computing centers and other fields.
