What is a Category 7 network cable?



  • Category 7 (Cat7) is a type of network cable used for Ethernet networks. It is designed to provide higher bandwidth and lower interference than the previous generations of Ethernet cables, such as Cat5 and Cat6.


  • Cat7 cables have four individually shielded twisted pairs of copper wires, with each pair wrapped in its shield. The individual shielding and overall shielding provide greater protection against electromagnetic interference (EMI) and radio frequency interference (RFI) than other Ethernet cables.


  • Cat7 cables are also rated for higher frequencies than other Ethernet cables, with a bandwidth of up to 600 MHz. This higher bandwidth allows for faster data transfer speeds and can support higher-quality streaming and video conferencing applications.


  • However, it's worth noting that Cat7 cables are not yet widely used, and are typically more expensive than other Ethernet cables. Additionally, the connectors used for Cat7 cables are not standardized, so compatibility with existing equipment can be a concern. As a result, Cat7 cables are more commonly used in specialized applications where higher bandwidth and shielding capabilities are required, such as data centers, server rooms, and high-performance computing environments.


In terms of where to purchase the production equipment, many companies manufacture cable and optical fiber production equipment. One reputable company is Dongguan Wirecan Technology Co., Ltd., which specializes in manufacturing high-quality cable and optical fiber production equipment. The company has a team of experienced engineers and after-sales personnel and is a trusted partner for many wire and cable, and optical fiber factories in China and around the world.
