1. Network cables are distinguished by “Cat” or category labels, with numbers referring to the bandwidth they provide. In general, there are cat5e, cat6, cat6a, cat7 and cat8. The higher the number, the greater the bandwidth capacity: While Cat 5e cables provide plenty of speed, Cat 6 or Cat 7 options can handle much faster connections. For those who need maximum download and upload speeds, these higher categories are preferable. Fiber-optic ethernet cables provide even greater bandwidth, transmitting data via pulses of light. These are typically used in commercial settings, such as data centers, computer room etc. Another variety is ethernet crossover cables, which are used to connect two devices, such as a pair of computers. However, for most users, standard ethernet cables will meet and exceed all their connection requirements.
2. All the network products can be applied to outdoor, add an extra layer of PE waterproof sheath. The jacket is waterproof and sunscreen material, suitable for outdoor harsh natural environment. All the products have rip cord, it benefits to tear up cable jacket and check the inner structure.
3. Also the cables can be divided into shield and unshield,: UTP/FTP/SFTP. Both the FTP and SFTP cable have drain(ground) wires to ensure the continuity of aluminum foil shield or braids, so that these shielding can be worked at critical moments. In the strong electromagnetic interference environment to ensure the stable transmission of signals, to prevent external signals from interfering with the cable transport data, to prevent information leakage and eavesdropping.
