Jumper: the main character ignored in Integrated Wiring

Integrated Wiring System is the most basic system in smart buildings in modern society. At present, the information industry is developing rapidly, and the importance of networks has been deeply imprinted in people's minds, networks have become an irreplaceable part of our lives. For the most important hardware supporting the network, the performance of the integrated wiring system directly affects the transmission performance of the network.

In the integrated wiring system, only the most rigorous TIA standard test can ensure the overall system performance. In a complete and good channel, the main components include twisted pair wires, modules, distribution frames and jumpers. Here, we will mainly talk about jumpers in cabling.

Speaking of jumpers, I believe that people with basic knowledge will think that this is no longer a simple connection line. As long as there is a crystal head, we can make various jumpers, such as 568A, 568B, direct connections, and interconnection lines, you can even make your own "568C", "568 ..." N jumpers! Although it is a bit exaggerated, it exists in actual construction and application, no matter what the method is, as long as it can be connected. On the internet baidu, for example, "how to create a network cable", there are N pieces of information, which teach you how to make your own jumper. For the moment, no matter how high your own production performance is, I think, in use, presumably, some people often encounter network disconnection or after a period of normal use, they cannot connect to the network, and re-plugging the PC network cable can be used again, or, after a long period of use, the cable and the crystal head may be poorly connected. These causes are almost all accidents caused by the direct or indirect production of jumpers. If such cables are used in structured Integrated Wiring of medium and large buildings, the results can be imagined that the light networks cannot work normally, serious customers will cause loss of incalculable losses to you or your enterprise or organization, and cause waste of manpower, financial resources, material resources, and other resources to the enterprise or organization, resulting in increased costs.

In some projects, the construction personnel often use the discarded twisted pair wires during the construction, from the market to buy ordinary crystal head to make their own jumper, but the British Ida news here is not recommended to make their own jumper, there are several main reasons:

1. Self-made cat6 jumpers cannot be tested by components of a single product in TIA/EIA,

2. In the channel test, self-prepared Jumpers are used for testing. In the whole channel, even if other plug-ins or copper cables pass the test completely or are higher than the TIA/EIA standard, the result we tested is also not passed,

3. In the TIA standard, it is not recommended that field jumpers be used in cabling systems.

4. Because the self-made patch cord core is a single-core wire, after multiple plugging, it is easy to break.

5. Self-made jumpers directly affect the performance of the entire channel during testing, resulting in failure to pass the test, resulting in failure to pass the acceptance of the entire project.

6. It affects the performance of the products provided by the wiring manufacturer. This damages the product image.

7. The transmission bandwidth in the cabling cannot be met.

Of course, the above are only problems encountered during construction. The problems in use will be more serious, as we mentioned earlier. In order to make the products used have higher transmission performance in engineering and use, we do not recommend using self-made jumpers in TIA standards. Of course, when the manufacturer makes a solution for the project, it has listed the patch cord of the manufacturer's supporting specifications in the solution.

So what are the differences between the patch cord from the manufacturer and the self-made patch cord? We will compare the following with the ADDISON cat6 patch cord.

① Crystal head

The general patch cord is usually a multi-piece set of two or three sets), the front of the contact metal objects are gold plated copper gold finger, and the use of polishing crystal head front of the metal Gold finger, not only has a strong hardness, in addition, it has good toughness to ensure that each wire core has good contact and transmission performance with the crystal head metal needle. At the same time, it also has a bracket, plug-in core and other plug-ins that further enhance the performance and stability, the metal contact body of the general crystal head is copper and only one crystal head. There is no other plug-in. When the hardness of the metal shrapnel is poor, the metal shrapnel cannot be inserted into the wire of twisted pair wires, the crystal head will not work; when the toughness does not meet the requirements, it is easy to break the metal shrapnel, such:

② Jumper cable

Jumper special wire is generally multiple copper wire, with better flexibility, high transmission rate. It is easy to move and carry, and can maintain the performance of cables. It is not easy to break or bend. The self-made wire is generally a common twisted pair wire, single-core, poor flexibility, with the passage of time, single-core copper wire may be broken. In order to reduce costs, some manufacturers mostly use galvanized copper or oxidized copper as the copper core, and there is no strict technical requirement on the twisted pair of the wire, which directly affects the performance of the Jumper.

③ Injection Molding

ADDISON patch cord injection is a very strict process. It has a great relationship with precision equipment and directly affects the performance and durability of patch cords, the injection jumper greatly increases the connection adhesion between the wire and the crystal head to ensure that repeated use will not cause any problems. The self-made jumper is generally not injected, and the problem is obvious. After repeated plugging and use, it is easy to fall off or break the wire between the crystal head and the wire.

④ Production ProcessFrom selecting materials to leaving the factory, the ADDISON patch cord of Ida will go through dozens of processes, each of which must undergo rigorous tests, and production must also be completed using special equipment in a specific environment, self-made jumpers can be completed with a network cable suppression tool.

⑤ Jumper Test

To ensure the quality of each factory jumper, professional jumpers must undergo rigorous tests. Tests are conducted according to EIA/tia patch cord Cat 5e/6 xx m and other standards. The NEXT margin of the most important test parameters in the factory test), RL echo) can only be measured through professional testing instruments, only when all the parameter tests are completely passed, can be factory. The self-made jumper uses a common wire measuring instrument to only test the wiring diagram. More performance tests cannot be completed, affecting the performance of the entire Link.

Through the comparison above, we can intuitively compare the self-made jumper with the professional jumper. Currently, high-bandwidth network cabling has been applied to smart buildings, and self-made jumpers cannot meet the actual needs. Jumper, which is the only exposed wire and mobile feature in Integrated Wiring, has a beautiful appearance and is also an important reference for durability.

The ADDISON patch cord series of IDA news ensures the communication performance in the link and strict production process. Each patch cord is delivered only after passing the test. The performance of the patch cord can be intuitively seen through the test report attached to the product, it fully meets or is higher than EIA/TIA standards to ensure the best performance for customers.
