What is Cat7 Ethernet Cable? Cat7 vs Cat6 Cable? What is the difference between Cat6 and Cat7?

What is Cat7 ethernet cable? Category 7 network cable is an 8-core shielded cable. Unlike ordinary shielded cables, the Category 7 system is based only on shielded cables. In Category 7 cables, each pair of wires has a shield layer. The four pairs of wires together have a common large shield layer.

Category 7 system can provide at least 500MHZ of comprehensive attenuation to crosstalk ratio and 600MHZ of overall bandwidth. It is mainly suitable for 10G Ethernet, which is more than twice that of Category 6 and Category 6A cables, and the transmission rate can reach 10Gbps.

Currently, Cat7 ethernet cables are not widely used, mainly because the standards and interfaces are not unified, the cost price is also high, and the application range is not wide.

Cat6 vs Cat7, What is the difference between Cat6 and Cat7?

Category 6A cable:

The maximum transmission frequency is 500MHz, which is twice that of Category 6 cable. It is mainly used for 10G (10G) networks. The outer skin is marked with “CAT.6A”. In addition, Category 6A network cables support 10G Ethernet. There will be a similar logo of 10Gigabit on the appearance.

There are two types of Category 6 cables. Generally, the diameter of a single strand of bare copper wire is 23AWG, which is approximately equal to 0.573 mm. There are also 24AWG Category 6 cables, which are approximately 0.511 mm thick.

Category 7 cables:

The performance of Cat7 ethernet cable is similar to that of Category 6e cables. It uses 8 pure copper cores and has a shielding layer. It has more powerful performance and can reach a transmission rate of 10Gbps. It is used in data centers and other occasions.

Each pair has a shielding layer (usually a metal foil shield). Then there is another shielding layer outside the 8 cores. It is generally a metal braided screen. The interface uses gg45 and tera interface. Total shielding + wire pair shielding (usually a metal foil shield). Category 7 cable S/FTP Cat.7 (HSYVP-7) has a maximum transmission frequency of 600MHz. The transmission frequency of Category 7e cable is 1000MHz. Category 7 fully supports 10G.

The core of Category 7 cable uses high-quality oxygen-free copper with a diameter of nearly 0.58mm as the transmission conductor. It is slightly thicker than Category 6 cable. Chemical foam insulation is used to greatly improve the transmission capacity of a single conductor.

What crystal head is used for Cat7 Ethernet Cable? How to make a crystal head?

1. Cat7 Cable Crystal Head

You can see that the Cat7 ethernet cable crystal head has a metal shielding shell. Because the Cat7 cable adopts a single-pair shielding and then a total shielding structure, the Category 7 crystal head is shielded, which can more effectively eliminate the crosstalk between the wire pairs.

2. Cat7 Ethernet Cable Crystal Head Production

The tools required: Cat7 crystal head, wire stripper, scissors, Category 7 network cable pliers, and wire tester.

In order to be more vivid, we will use a video to learn more about the production process of Category 7 network cable crystal head.

Application of Cat7 Cable

Category 7 network cables are generally used in scenarios with high-speed transmission and high bandwidth requirements. For example, video conferencing and streaming media broadcasting. As well as network-based voice calls, grid computing and storage network scenarios. Because it is suitable for 10/100/1000/10GBASE-TX Ethernet data transmission. Therefore, it is also widely used in indoor high-demand horizontal wiring. Due to the super shielding function of Category 7 cables, it is very suitable for the wiring of shielded computer rooms and confidential networks.
