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

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.

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

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.

With the rapid development of communication technology, optical fiber communication systems have been widely used, from the initial use of long-distance communication lines, to optical fiber to roads, optical fiber to buildings, optical fiber to homes. Fiber optic cable barrier is the main factor that causes communication interruption. About two-thirds of the statistical barriers are fiber-optic barriers. In order to ensure that optical fiber lines are not blocked, a series of measures are taken. For example, in the construction of optical cable, corresponding protection measures should be taken according to the use environment. Carry out routine inspection system, routine maintenance test, etc. Due to the extensive use of optical cable lines and long lines, there will inevitably be failures during use. To ensure the quality of communication, it needs to be repaired immediately. Finding the exact point of failure is the main step in achieving a quick fix.

Jiangsu DMIS has recently released a new optical cable with strict bending radius requirements. The company's latest optical cable product states that the bending radius of the cable should not be less than 15 times the outer diameter, and should not be less than 20 times during the construction process. This requirement ensures the durability and reliability of the optical cable during installation and usage. The company's dedication to providing high-quality materials for the telecommunications industry is evident in this latest product release. Customers can rely on Jiangsu DMIS for top-notch optical cable solutions that adhere to strict standards for performance and longevity
