The manufacture of the skeleton cable is mainly to place the optical fiber belt in a specific shape of the skeleton slot to form a closed cavity to protect the optical fiber. Its application scenarios include urban backbone network construction, long-distance trunk transmission and remote communication .
The manufacturing process of the skeleton cable
Firstly, material preparation is a key step. It is necessary to choose high-quality raw materials, such as fiber optic tape, hose block, double-sided plastic steel tape and polyethylene outer coating material. The choice of these materials directly affects the performance and quality of the skeleton cable .Next comes the pre-processing phase. The selected material is cleaned and dried to ensure that the surface of the material is free of impurities and moisture, providing a good basis for subsequent processing and assembly .
Then there is structural assembly . The fiber strip is placed in a matrix form in a specific skeleton slot, such as a U-shaped spiral skeleton slot or an SZ spiral skeleton slot. The hose is wrapped around the skeleton to form a closed cavity with the skeleton to protect the fiber from moisture erosion. In addition, the hose is longitudinally covered with double-sided plastic steel tape to enhance the mechanical strength of the optical cable .Molding and curing is an important part of the manufacturing process. The assembled skeleton cable is formed by the mold and solidified to ensure the structural stability and reliable performance .
Finally, inspection and packing . Quality inspection of the finished skeleton cable, including fiber transmission performance, mechanical strength, water resistance and other aspects of the test. After passing the inspection, it will be packed and stored for subsequent sale and use.
The main application scenarios of the skeleton cable
Urban backbone network construction: skeleton-type optical cable has strong transmission capacity and large capacity depth, suitable for high-speed transmission infrastructure within the city, mainly carrying data transmission between urban subnets. Because of its flexible laying method, it is mostly laid on high-speed Bridges and railway viaducts, so it can cover a large area of transmission network in the city.
Long-distance trunk transmission: skeleton type optical cable is also widely used in long-distance trunk transmission, such as railway, automobile passenger transport, international expressways and so on. Laying next to high-speed railways or highways, optical cable can provide the same transmission speed and reliability as high-speed railways or highways, and become a necessary choice for long-distance trunk line transmission .
Telecommunication: With the rapid development of the Internet, the demand for telecommunication and remote cooperation has increased. Skeleton-type optical cable can provide almost unlimited bandwidth, stable and reliable, fast transmission speed, low latency, is very suitable for this application .
conclusion
In addition, the skeleton-type optical cable also has the advantages of high optical fiber assembly density, good lateral compression resistance and high connection efficiency, especially for trunk networks and access networks . Its dry water blocking structure overcomes the shortcomings that traditional oil paste is not easy to remove, reduces the construction preparation time, improves the connection efficiency, and is convenient for construction and maintenance.
