The cross section is in a figure-8 shape. The reinforcement is located in the center of the two circles. Metal or non-metallic structure can be used. . The optical fiber in the leather cable adopts G.657 small bending radius optical fiber, which can be laid with a bending radius of 20mm.

Speaking of optical cables, we have talked a lot, such as the development trend of optical cables and how to repair optical cable line failures. I don't know if you have ever heard of a leather cable, what exactly is a leather cable? What are the construction specifications for leather cable?

What is a leather cable

The sheathed optical cable is mostly single-core or double-core structure, and can also be made into a four-core structure. The cross section is in a figure-8 shape. The reinforcement is located in the center of the two circles. Metal or non-metallic structure can be used. . The optical fiber in the leather cable adopts G.657 small bending radius optical fiber, which can be laid with a bending radius of 20mm.


What are the construction specifications of leather cable

1. The type of user's residential building, environmental conditions and the routing of existing cables should be considered before the installation of household optical cables. At the same time, it is necessary to comprehensively judge the economy and safety of construction, the convenience of future maintenance and user satisfaction. .


2. Use the existing hidden pipes to lay the optical cables. For residential buildings without hidden pipes or where the hidden pipes are not available, the butterfly-shaped incoming optical cables should be laid by laying corrugated pipes in the building.

3. For residential buildings with vertical wiring bridges, corrugated pipes and floor crossing boxes should be installed in the bridges to pass through the butterfly drop cables. If there is no space to install the corrugated pipe in the bridge, the winding pipe should be used to wrap the butterfly-shaped lead-in optical cable laid in it to protect the optical cable.


4. Since the butterfly drop cable cannot be immersed in water for a long time, it is generally not suitable for laying directly in the underground pipeline.


5. The minimum bending radius of the butterfly drop cable should be in accordance with: it should not be less than 30mm during the laying process; it should not be less than 15mm after fixing.


6. Under normal circumstances, the traction force of the butterfly drop cable should not exceed 80% of the allowable tension of the cable; the instantaneous maximum traction force should not exceed 100% of the allowable tension of the cable, and the main traction force should be added to the strengthening member of the cable.


7. The optical cable reel should be used to carry the butterfly-shaped incoming optical cable, and the cable release bracket 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 laying the optical fiber, the tensile strength and bending radius of the optical fiber should be strictly paid attention to to avoid the optical fiber from being twisted, twisted, damaged and stepped on.


The above is what is the leather cable and the construction specification of the leather cable. In fact, the leather cable is commonly known as the indoor hanging wiring cable. With the domestic optical fiber access market showing a good momentum of development, optical fiber access has become a hot spot in the field of optical communications.
