UTP (Unshielded Twisted Pair) connectors are modular connectors used in structured cabling to connect network devices such as computers, servers, and routers. They use unshielded twisted copper wires to transmit data and signals.
There are several categories of UTP connectors, each of which defines the maximum data transmission frequency and bandwidth it can support:
Category 3: Maximum frequency 10 MHz, bandwidth up to 10 Mb/s. Applications: telephone networks, old LAN systems.
Category 4: Maximum frequency 16 MHz, bandwidth up to 16 Mb/s. Applications: 10BASE-T networks.
Category 5: Maximum frequency 100 MHz, bandwidth up to 100 Mb/s. The most popular category, used in 100BASE-TX networks.
Category 5e: Enhanced Category 5, offering better performance at higher frequencies. Maximum frequency 125 MHz, bandwidth up to 1 Gb/s. Used in Gigabit Ethernet networks.
Category 6: Maximum frequency 250 MHz, bandwidth up to 10 Gb/s. Used in 10 Gigabit Ethernet networks.
Category 6a: Enhanced Category 6, offering better performance at higher frequencies. Maximum frequency 500 MHz, bandwidth up to 10 Gb/s.
Category 7: Maximum frequency 600 MHz, bandwidth up to 40 Gb/s. Used in 40 Gigabit Ethernet networks.
Category 7a: Enhanced Category 7, offering better performance at higher frequencies. Maximum frequency 1000 MHz, bandwidth up to 100 Gb/s.
When choosing a UTP connector category, consider the data transmission speed you want to achieve and the distance over which the signal needs to be transmitted. The higher the category, the higher the speed and range.
In addition to the category, you should also pay attention to the type of connector:
Male connector (RJ-45): A plug that is connected to a network device.
Female connector (RJ-45): A socket that is mounted in a wall outlet or patch panel.
