How to distinguish between network cables and telephone lines?
The connector of a Ethernet cable is larger, and the wire itself is thicker. It is commonly used to connect devices like routers and computers for internet access. The outer jacket of the network cable typically has labels like “Cat 5E” or “Cat6”, which indicate the cable’s specification.
The connector of a telephone cable is smaller, and the wire is thinner. It is usually used to connect landline phones, and the outer jacket typically doesn’t feature labels like “Cat.”
Additionally, network cable connectors contain 8 small metal pins, while telephone line connectors have only 2 to 4.
