Cat7 and Cat8 ethernet cables use different types of connectors.

Cat7 cables typically use RJ-45 connectors, which are widely used in networking. However, Cat8 cables often employ newer and more advanced connectors such as TERA or GG451. These connectors offer improved performance and durability compared to RJ-45 connectors.

The main differences between the connectors used for Cat7 and Cat8 cables compared to other ethernet cables are:

Shielding: Cat7 connectors have individual shielding for each twisted pair and an overall shielding layer. Cat8 connectors have even better shielding capabilities, including individual shielding for each twisted pair, an overall shielding layer, and additional shielding for each plug.
Performance: Cat8 connectors are designed to support higher frequencies and faster speeds, up to 40 Gbps over a 30-meter distance at 2 GHz, compared to Cat7's 10 Gbps at 100 meters.
It's important to note that while Cat7 connectors are backward compatible with previous Ethernet standards, Cat8's newer connectors may require different ports or adapters to be compatible with existing equipment.
