The Rj-45 Plug
- Sep 27, 2018 -

The rj-45 plug is a plastic connector that can only be inserted in a fixed direction and automatically prevents shedding, commonly known as the "crystal head," or rj-45 connector. It is called "crystal head" because of its bright and shining appearance. The rj-45 plug must be installed at both ends of the twisted pair to connect to the rj-45 interface of the NIC, Hub, or Switch.
