Since the birth of the concept of structured cabling, command signals, control signals, and communication signals have been centrally transmitted through a common structured cabling system. Now, a structured cabling system in the building can support signal transmission, such as voice, data, images, security, and building automation. With the promulgation of the latest TIA/EIA and ISO Cabling Standards, the standards are becoming increasingly important and all vendors and installers must comply with the standards. The standard defines in detail the system components, installation methods, performance, and methods of system testing and authentication.

The application requirements in the modern business environment promote the rapid development of data networks to meet the reliability and high performance requirements of Network Systems in the commercial environment. Network devices, such as information modules, are designed to support transmission of High-speed and large-capacity data networks better than previous products. These information modules play a very important role in network data transmission. The features and design of modules are very important to network performance.

The publication of new industry standards for TIA/EIA and ISO promotes the use of higher-performance structured cabling systems to support high-speed data transmission. Data Modules in structured cabling systems have become an important transmission component. The module provides connections between the level subsystem and jumper. Although he is the shortest connection unit in the Link, he makes great contributions, such as transmission loss. Therefore, it is vital to improve the features and structure of the module.

A function of the data module is to provide reliable connections between the cabling system and the jumper. The module impedance must match the impedance of the cable to minimize signal reflection. In addition, within the warranty period of 20 years or longer, the electrical characteristics of the module cannot be faulty. There are two types of module production technology on the market to ensure the frequency characteristics of the module: PCB printed circuit board technology) and LFT lead frame technology ).

The printed circuit board solution is the earliest and most common method for compensating the connection hardware frequency. These printed circuit boards are designed with special paths based on known twisted pair transmission characteristics. Impedance Matching is done through a special path on the printed circuit board. Some problems may occur in the use of data modules using PCB technology, because solder joints on the circuit board are loose and oxidized after a long period of use, resulting in changes in electrical characteristics and performance degradation.

On the other hand, the wire frame technology is a structure that uses metal stamping to control the bending of the wire. The shape with close lead curvature can reduce the influence of unwanted features. The use of LFT means that there are no solder joints in the IDC and RJ45 sockets, and there are no linkage components like resistance and capacitance. Therefore, the module does not contain errors of PCB and Other components. It is a more advanced connection mode and does not affect the system performance because of changes in electrical performance due to time issues.

Structured Cabling Overview

We have shown you the importance of Structured Cabling solutions for business environments and discussed the future trend of network speed and bandwidth development. We cannot ignore factors such as connection reliability and warranty period. Compared to adopting outdated PCB technology at the same cost, the lead frame technology provides a more advanced solution. When someone has been arguing that the average failure time of PCB-type modules can be measured, more professional engineers certainly know that the average failure time of the network is the total average duration of each individual component. A large network may contain 2000 to 20000 modules, and the overall system error probability will be higher. If a module encounters a problem, network engineers need to look for a wrong module like a haystack. It brings huge losses to the entire network.

The solution of the data module in structured cabling has been introduced to you. I hope you have mastered it.
