What's the difference between Cat-6a and Cat-6 network cables?

Here are the differences between Cat-6a and Cat-6 network cables:

Bandwidth and Rate:
Cat-6a Ethernet cable: With a bandwidth of 500 MHz, it’s primarily designed for 10Gbps network connections and can support 10-gigabit speeds.
Category 6 Ethernet cable: With a bandwidth of 250 MHz, it’s ideally suited for 1Gbps network connections and supports gigabit speeds.
Visual identification:
Cat-6A Ethernet cable: The cable jacket is marked with "CAT6A."
Category 6 cable: The marking on the cable jacket is "CAT6."
Conductor Core and Structure:
Cat-6e network cables feature thicker wire cores, with conductor diameters measuring 0.57 ± 0.02 mm, and tighter cable twists. Some Cat-6e cables also incorporate a more rigorous shielding design, resulting in an overall larger outer diameter.
Category 6 network cables: The conductor material in unshielded cables measures 0.57 ± 0.02 mm and features an insulated cross-shaped separator—but this separator isn’t always shaped like a gear with grooves. Additionally, some Category 6 cables either lack a shielding layer altogether or have a relatively weak shielding effect.
Transmission distance:
Cat-6a Ethernet cable: According to the IEEE 802.3an standard, it supports a maximum transmission length of 100 meters.
Category 6 Ethernet cable: Supports 10GBase-T transmission up to a length of 55 meters.
Price:
Cat-6e network cables: relatively higher in price.
Category 6 network cables: relatively affordable and offer excellent value for money, making them suitable for scenarios where network performance requirements aren't extremely high.
Applicable scenarios:
Cat-6E network cables: Ideal for data centers, large enterprise networks, and other environments with extremely high demands for network bandwidth and performance. They meet the needs of 10-Gigabit network transmission and support applications like HD video conferencing and massive data transfers.
Category 6 network cable: Suitable for home use, small business networks, and more, meeting the needs of everyday applications such as internet browsing, office tasks, and HD video streaming over gigabit networks.
