What is the difference between Ethernet cables Cat6 and Cat7?
The physical composition of Cat7 cable is similar to the previous Cat6 cable. Both versions use the same twisted pair shielded four pair cable design, capable of transmitting 10Gbps Ethernet signals with a transmission distance of up to 100m.
Cat7 has adopted dual shielding to meet stricter specifications. They can better shield EMI and crosstalk.
The main difference between Cat6 and Cat7 lies in speed and frequency. You may know that the maximum speed of Cat7 or Cat7a is 10000Mbit/s, and the maximum speed of Cat6 cable is 1000Mbit/s.
In addition, Cat7 has a higher frequency than Cat6. Therefore, CAT7 shielded Ethernet cables will be able to transmit data faster than Cat6 cables. The performance and lifespan standards of Cat7 shielded cables are also more stringent.
However, like many other such products, the key is to select the most suitable product for your job at the most cost-effective price based on the required conditions to meet these requirements. Cat7 is mainly used in data centers.
