Drop optical cable, also known as butterfly optical cable, figure-of-eight optical cable, is widely used in residential building access networks because of its softness and lightness. What problems should be paid attention to in the project for the covered optical cable? The following are the construction specifications of some covered optical cables.
First of all, 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 cable with corrugated pipes in the building. For residential buildings with vertical cabling bridges, it is advisable to install corrugated pipes and floor crossing boxes in the bridges for threading and laying down leather cables. If there is no space to install the corrugated pipe in the bridge frame, a winding pipe should be used to wrap the covered optical cable to protect the optical cable.
Secondly, the minimum bend radius for laying leather cable should conform to: during laying it should not be less than 30mm; after fixing it should not be less than 15mm. Since the covered cable cannot be immersed in water for a long time, it is generally not suitable to be laid directly in an underground pipeline.
It should be noted that the traction force during laying of the sheathed optical cable should not exceed 80% of the allowable tension of the optical cable; the instantaneous maximum traction must not exceed 100% of the allowable tension of the optical cable, and the main traction should be added to the reinforcing member of the optical cable.
In addition, the optical cable reel should be used to carry the drop 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. During the laying process of the covered optical cable, strict attention should be paid to the tensile strength and bending radius of the optical cable to prevent the optical cable from being entangled, twisted, damaged and stepped on.
