CAT5e and CAT6 bandwidth
Both CAT5e and CAT6 from China FTP CAT6 Cables manufacturers can handle speeds up to 1000 Mbps or gigabits per second. This is sufficient for the speed of most Internet connections to date. It is very unlikely that you currently have an Internet connection that can reach speeds of 500 Mbps.

The main difference between CAT5e and CAT6 cables is the bandwidth, and the cable can support data transmission. The CAT6 cable is designed for operating frequencies up to 250 MHz, while the CAT5e operating frequency is 100 Mhz. This means that CAT6 cables can process more data at the same time. Think of it as the difference between a 2-lane and a 4-lane highway. Both can travel at the same speed, but a 4-lane highway can handle more traffic at the same time.

CAT5e and CAT6 speed
Since the performance of CAT6 cables is up to 250 MHz, which is more than twice that of CAT5e cables (100 Mhz), they provide speeds up to 10GBASE-T or 10-Gigabit Ethernet, while CAT5e cables can support up to 1GBASE-T or 1-Gigabit Ethernet.

CAT5e and CAT6 crosstalk
Both CAT5e and CAT6 are twisted-pair cables. Both use copper wires, and each cable usually has 4 twisted pairs (8 wires). In the past, the 250 MHz performance provided by CAT6 was usually achieved through the use of nylon splines in the cabling, which isolates each of the four twisted pairs to make the cable rigid. Today, CAT6 cables are more flexible and use other methods to reduce noise.

Whether using splines or not, FFTP CAT6A Cables Manufacturers' CAT6 has stricter crosstalk and system noise specifications. Compared with CAT5e, CAT6 not only provides significantly lower interference or near-end crosstalk (NEXT) in transmission, but also improves equal-level far-end crosstalk (ELFEXT), return loss (RL) and insertion loss (IL) . The result is less system noise, fewer errors, and higher data transfer rates.
