UTP Modular Plug

RJ45 connector, which is commonly used for network cabling.

An RJ45 connector is a standardized interface for connecting devices to a network, like a computer to a LAN. 

Function: It terminates the Ethernet cable, enabling it to interface with networking hardware such as modems, routers, or servers.
 
Components: It consists of a plastic body with eight gold-plated contacts inside. 

Usage: RJ45 connectors are used for plugging internet-enabled devices directly into network hardware. 

Data Transmission: They support data transmission speeds from 10 Mbps to 10 Gbps or higher, depending on the Ethernet standard and cable quality. 

Power over Ethernet (PoE): Some RJ45 connectors can deliver electrical power to connected devices. 

Wiring Schemes: RJ45 connectors use two wiring schemes: T568A and T568B. 

Types: While externally similar, internal differences exist to accommodate various cable types and performance requirements.
