Why does CAT5E/CAT6 Shielded Pass-Through Module support transmission frequencies up to 250MHz?- Cixi Shuaiye Communication Equipment Co., Ltd

1. The role of built-in circuit board (PCB)
The CAT5E/CAT6 Shielded Pass-Through Module integrates a circuit board, which is a very critical design. The main function of the circuit board is to improve near-end crosstalk, that is, when data is transmitted through the network cable, signal interference may occur between different lines. The circuit board of this module adopts efficient crosstalk compensation technology, which effectively reduces signal loss and transmission errors caused by electromagnetic interference. Therefore, the module can support frequencies up to 250MHz and maintain the stability of data transmission.

2. Selection of high-hardness phosphor copper contact parts
CAT5E/CAT6 Shielded Pass-Through Module uses high-hardness phosphor copper as the material of the contact part, and is plated by nickel-gold process. Phosphor copper material has excellent conductivity, wear resistance and corrosion resistance, so it can reduce contact resistance and ensure efficient signal transmission.

The use of nickel-gold process not only increases the durability of the contact points, but also reduces the signal attenuation caused by oxidation and corrosion, and improves the durability and stability of the module. These features enable the module to perform efficient data transmission at a higher frequency, support the frequency requirement of 250MHz, and at the same time extend the service life of the module and reduce maintenance costs.

3. Design to support Gigabit Ethernet
The design of CAT5E/CAT6 Shielded Pass-Through Module meets the requirements of Gigabit Ethernet and can support high-speed transmission of 1000Mbps. To achieve this goal, the module must have a higher transmission frequency and low crosstalk performance. According to the standard, the frequency requirement of Gigabit Ethernet network is usually 250MHz, and this module achieves this goal by adopting advanced crosstalk compensation circuits, high-quality materials and sophisticated process design.

Supporting the transmission frequency of 250MHz is to ensure that the network can stably transmit large amounts of data, especially in high-bandwidth demand occasions such as data centers, enterprise networks and high-speed Internet access. This enables CAT5E/CAT6 Shielded Pass-Through Module to provide high-speed and stable data connections in various network environments.

4. Anti-interference capability and shielding design
The module adopts a shielding design, that is, a metal shielding layer is added between the module housing and the line to reduce external electromagnetic interference. Electromagnetic interference is one of the main factors affecting the stability of high-speed networks, especially in high-frequency transmission, the signal is easily interfered by external electromagnetic waves.

5. Plug-in life and reliability
The plug-in life of the CAT5E/CAT6 Shielded Pass-Through Module reaches more than 800 times, which means that the module can withstand frequent plug-in and plug-out use and maintain excellent performance for a long time. This feature is very important because transmission at high frequencies requires higher contact stability and reliability.
