Code for construction of pigtail and optical cable

Speaking of optical cable, we have talked a lot, such as the development trend of optical cable and how to repair the fault of optical cable line, etc. I wonder if you have ever heard of leather fiber optic cable. What is leather fiber optic cable? What are the construction specifications for leather and optical cables?
What is leather cable
Most of the pigtail optical cables are single core and double core structures, and can also be made into four core structures. The cross section is 8-shaped. The stiffener is located in the center of two circles, which can adopt metal or non-metal structure. The optical fiber is located in the geometric center of 8-shaped. G.657 small bending radius optical fiber is used as the optical fiber in the pigtail optical cable, which can be laid with a bending radius of 20mm, which is suitable for entering the house in the building in the form of pipeline or open line.

What are the construction specifications for pigtail and optical cable

1. The type of residential buildings, environmental conditions and the laying route of existing cables shall be considered before the laying of household optical cables. At the same time, it is necessary to make a comprehensive judgment on the economy and safety of construction, the convenience of future maintenance and user satisfaction.
2. The existing indoor concealed pipe shall be used as much as possible to lay the indoor optical cable. For residential buildings without concealed pipe or where the indoor concealed pipe cannot be used, the butterfly incoming optical cable shall be laid by laying corrugated pipe in the building.
3. For residential buildings with vertical wiring bridges, corrugated pipes and floor crossing boxes should be installed in the bridges for threading butterfly incoming optical cables. If there is no space to install bellows in the bridge, wrap the butterfly incoming optical cable laid inside with winding pipe to protect the optical cable.
4. Because the butterfly incoming optical cable cannot be immersed in water for a long time, it is generally not suitable to be laid directly in underground pipelines.
5. The minimum bending radius of laying butterfly incoming optical cable shall meet the following requirements: it shall not be less than 30mm during laying; It shall not be less than 15mm after fixing.
6. In general, the traction force during the laying of butterfly lead-in optical cable shall not exceed 80% of the allowable tension of optical cable; The instantaneous maximum traction force shall not exceed 100% of the allowable tension of the optical cable, and the main traction force shall be added to the reinforcing member of the optical cable.
7. The optical cable reel shall be used to carry the butterfly incoming optical cable, and the cable laying bracket shall be used when laying the optical cable, so that the optical cable reel can rotate automatically to prevent the optical cable from being wound.
8. In the process of optical cable laying, pay strict attention to the tensile strength and bending radius of optical fiber to avoid winding, torsion, damage and trampling of optical fiber.

The above is all about what is pigtail optical cable and what are the construction specifications for pigtail optical cable. In fact, pigtail optical cable is commonly known as indoor suspended wiring optical cable. When the domestic optical fiber access market shows a good development momentum, optical fiber access has become a hot spot in the field of optical communication.
