As a fiber optic cable manufacturer with 17 years of production experience, GL's Drop Fiber Optic Cables are exported to 169 countries abroad, especially in South America. According to our experience, the structure of the sheathed fiber optic cable mainly includes the following structures:
Construction Precautions：
1. Before laying the home fiber optic cable, the type of user's residential building, environmental conditions and the routing of the existing cable should be considered. At the same time, it is necessary to make a comprehensive judgment on the economy and safety of the construction, the convenience of future maintenance and user satisfaction. .
2. The existing concealed pipes should be used as much as possible to lay the optical fiber cables. For residential buildings without concealed pipes or unavailable concealed pipes, it is advisable to lay the butterfly-shaped drop cables by laying bellows in the building.
3. For residential buildings with vertical wiring bridges, it is advisable to install corrugated pipes and floor crossing boxes in the bridges for putting butterfly-shaped drop cables. If there is no space to install the corrugated pipe in the bridge, the winding pipe should be used to wrap the laying of the butterfly-shaped drop optical cable to protect the optical cable.
4. Since the butterfly-shaped drop cable cannot be immersed in water for a long time, it is generally not suitable to be laid directly in an underground pipeline.
5. The small bending radius of the butterfly-shaped drop optical cable should comply with: during the laying process it should not be less than 30mm; after fixing it should not be less than 15mm.
6. Under normal circumstances, the traction of the butterfly drop cable should not exceed 80% of the allowable tension of the optical cable; the instantaneous traction must not exceed the allowable tension of the optical cable, and the main traction should be added to the reinforcing member of the optical cable.
7. The optical cable reel should be used to carry the butterfly-shaped drop-in optical cable, and the cable tray should be used when laying the optical cable, so that the optical cable reel can automatically rotate to prevent the optical cable from being entangled.
8. In the process of optical cable laying, strict attention should be paid to the tensile strength and bending radius of the optical fiber to prevent the optical fiber from being twisted, twisted, damaged and stepped on.
