1. What is the difference between modular plugs and modular jacks?
A plug is a male connector with metal contacts, while a jack is a female connector that is usually mounted on a device or panel.
-
2. 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.
-
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. Does the metal contact material of the modular plug affect performance?
Yes, high-quality plugs usually have gold-plated contacts (such as 50 micro-inch gold) to improve corrosion resistance and conductivity and reduce signal loss.
