Cat 6 vs Cat 7 – Main Differences

Differences in speed and frequency are the main differences between Cat 6 and Cat 7. This ultimately results in faster internet speeds.

In terms of their build and physical appearance, there are a few differences between the two different ethernet cables. Cat 6 cables are designed with four twisted pair cables made out of copper. These are unshielded twisted pair wires. Cat 7 cables on the other hand are shielded twisted pair cables, shielded in foil. The shielding on the foiled twisted pair cables is designed to minimize noise and eliminate any crosstalk – be it alien crosstalk or near-end crosstalk.

Cat 7 Ethernet Cables

Cat7 cables are capable of supporting speeds up to 10 Gbps at a frequency of 600 MHz. As previously mentioned, they are designed with shielded wires to stop interference with signals from other devices. Cat 7 cables are great options for gaming and plenty of other networking systems. 

Cat 6 Ethernet Cables

Cat 6 cables are designed to support connection speeds of up to 10 Gbps at a maximum frequency of 250 MHz. When considering cat 6 vs cat 7, it is important to note that the performance of Cat 6 cables does begin to significantly decrease the longer the cabling length. A Cat 6 cable is constructed with RJ-45 connectors, that provide decent durability and are backward compatible with Cat 5 and Cat 5e. 

Is Cat 7 better than Cat 6?

Yes, Cat7 is a more recent iteration of ethernet than Cat6. Cat7 ethernet cables are better than Cat6 because they have a higher frequency rating and better overall construction. They also do a better job of eliminating crosstalk and interference and can retain speed over longer distances better.

Whats the difference between Cat 6 and Cat 7 cables?

Differences in speed and frequency are the main differences in Cat 6 vs Cat 7. This ultimately results in faster internet speeds. In terms of their build and physical appearance, there are a few differences between the two different ethernet cables. Cat6 cables are designed with four twisted pair cables made out of copper.

Cat 6 vs Cat 7 – Verdict

Cat6 cables are very common, and the standard for most homes and small businesses. For most people, Cat6 is completely adequate and will fulfill all of their networking needs. However, if you’re looking for the speediest, most advanced cables consider Cat7 instead.
