1. What are RJ45 plugs suitable for?
RJ45 plugs are mainly used in Ethernet networks (Cat5e, Cat6, Cat6a, Cat7), and can also be used in industrial automation and serial communications.
-
2. How do I crimp a modular plug correctly?
A special crimping tool is required to ensure that the wires are arranged in the correct order (such as T568A/T568B Ethernet standards).
-
3. What is the difference between shielded (STP) and unshielded (UTP) modular plugs?
STP plugs have an additional metal shielding layer to reduce electromagnetic interference (EMI) and are suitable for industrial and high-interference environments, while UTP is suitable for general network environments.
-
4. Can modular plugs be reused?
In general, it is not recommended to reuse crimped plugs because the deformation of the pins may cause poor contact and affect signal transmission.
