The communication cable is composed of a number of (core) optical fibers (generally from a few cores to thousands of cores) composed of the cable core and the outer protective layer. Compared with traditional symmetric copper loop and coaxial copper loop, the transmission capacity of optical fiber is much larger. Less decay; Long transmission distance; Small size; Light weight; No electromagnetic interference; Low cost, is the most promising communication transmission media.

Leather cable single-core, double-core structure is widely used, can also be made into a four-core structure, the cross section is 8, the reinforcement is located in the center of two circles, can use metal or non-metal structure, the fiber is located in the center of the 8-figure geometry

In the case of 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 communication. In the optical fiber access project, the indoor wiring near the user is the most complex link, the bending performance of conventional indoor optical cable, tensile performance can not meet the needs of FTTH (optical fiber to the home) indoor wiring, leather cable should be born, especially in the digital, network security era, the higher the demand for leather cable. Leather cable cable commonly known as indoor hanging cabling cable, some in 200 meters to 2 kilometers of wiring can be used leather cable cable wiring.

The most intuitive difference between the two is that only one end of the pigtail has a connector, and both ends of the jumper have a connector.

October 11 news, during the recently held 2024 World Fiber Optic Cable Conference, CRU chief analyst and cable group director Wang Chenfei, CRU senior analyst Vishnu Patidar introduced the current global fiber optic cable market pattern, and analyzed the trend of data center fiber optic cable demand driven by artificial intelligence applications.

Integrated cabling system test is a commonplace problem, because of its position in the integrated cabling system, we still have to deeply analyze the problems that need special attention in the actual operation process, which is very important to the tester, but also a very important part of the integrated cabling system program.

The requirements for the optical cable manufacturing process are simple and reliable, and the following points must be achieved according to the characteristics of the optical cable:

1, strictly control the role of pay-off and take-up tension on the optical fiber, ensure that the optical fiber is continuous in the manufacturing process, and the optical fiber is subjected to small stress and small residual stress;

Jiangsu DMIS recently announced its emergency plan for handling different types of line faults. In the event of a total resistance fault on a cable within the same route, the company's personnel are instructed to use an alternate fiber core to block services on the optical fiber and promptly repair the faulty fiber. However, if the fault occurs without the presence of an optical fiber, the repair process can be carried out directly following the principle of prioritizing important circuits. The company's proactive approach to handling line faults demonstrates its commitment to ensuring the smooth operation of its equipment and services

Optical cables are manufactured from an outer cover of a single, multiple optical fibers, or an external combination of optical fiber beams that serve as an indicator of optical characteristics, environmental performance, and a cable structural entity suitable for mechanical properties. There are mainly belt structure, bound structure, skeleton structure, and twisted head structure. In the 1980s, it was slowly applied to long-distance routes and gradually began to use a single model fiber optic cable. Over the years, cable technology has developed in a long-term and stable way.

1 Preliminary design

First, the designer contacts the customer, decides the address of the customer to use, obtains the relevant understanding, and helps the customer complete the initial plan of the Internet cable in the local urban area. Then, on the basis of the initial confirmation of the customer's access point, the resources of the customer's distribution cable are investigated to understand the number of fiber cores of the customer's distribution cable and the distribution of the customer's pipeline.

Secondly, taking into account the terrain and facilities, ground features and other factors where the customer cable line is located, taking into account the relevant provincial and administrative policies and release development requirements where the customer cable line is located, the designer will use a series of excellent comprehensive elements as the preliminary design of cable line selection.
