Here are several common types of network cables and their characteristics

Here are several common types of network cables and their characteristics:

Cat5 cable: The maximum transmission speed can reach up to 100 Mbps and is widely used.
Cat5e cable: The maximum transmission speed can reach up to 1 Gbps and is widely used for various applications such as networks, telephones, audio, and video.
Cat6 cable: The maximum transmission speed can reach up to 10 Gbps and is usually used in data centers or enterprise-level networks.
Cat6a cable: The maximum transmission speed can reach up to 10 Gbps and, compared to Cat6, it has a longer transmission distance of up to 100 meters. Cat7 cable: The maximum transmission speed can reach up to 40 Gbps and is usually used in high-performance computer networks.
Cat8 cable: The maximum transmission speed can reach up to 25 or 40 Gbps. Depending on the shielding method, network cables can be classified as shielded cables and unshielded cables. Shielded cables have anti-interference capabilities and are suitable for networks with strong interference. Unshielded cables do not have a shielding layer, have a simple structure, and are inexpensive, and are suitable for ordinary network environments. When choosing a network cable, it is necessary to select the appropriate type based on the transmission rate of the network equipment and the usage environment.
