Function This RJ45 Ethernet adapter cable provides a practical solution for routing cables and can also be used as an extension. Versatile Converts a single RJ45 port into two RJ45 sockets, allowing share of high-speed DSL, cable modem, and Ethernet connections without a router. Gold-plated core Delivers reliable connection and efficient transmission. The RJ45 socket helps prevent external signal interference and protects the internet signal. Durable The circuit board is embedded in the conductive path to prevent conductor damage and leakage, ensuring a longer service life. Materials and compatibility Standard RJ45 connectors designed for Ethernet networks, built for durable, long-term use. Use scenarios - Home: share one network line between two devices such as a PC and a smart TV or printer without needing a router. - Small office or dorm: supply two devices from a single DSL/cable modem Ethernet port for wired connections. - Temporary testing or setup: run two devices simultaneously with a single Ethernet port during evaluation or troubleshooting.
