Cat 8 Ethernet cable is the latest IEEE standard in copper Ethernet cable. It is the fastest Ethernet cable yet, with data transfer speeds of up to 40 Gbps, which is four times faster than Cat6a. It supports bandwidth up to 2 GHz, which is four times more than standard Cat6a bandwidth, reducing latency for superior signal quality. Cat8 Ethernet cable is ideal for switch-to-switch communications in data centers and server rooms, where 25GBase-T and 40GBase-T networks are common. Its RJ45 ends will connect standard network equipment, and it is backward compatible with previous standards. Cat8 cables support PoE technology, which means they can save space in server rooms by simplifying installation. However, Cat8 cable can be difficult to install in tight spaces due to its heavier gauge and rigidity. For most home networks, Cat6a is more than sufficient, even for gaming, and Cat8 cable can be overkill and difficult to install.
