UGREEN NW114 (20390) RJ45 Network Coupler - Black

The UGREEN NW114 (20390) is a handy RJ45 network coupler (female‑to‑female) designed to seamlessly connect two Ethernet cables together to extend your network link without rewiring or replacing cables. It works as an inline connector that joins two male RJ45‑terminated network cables — such as Cat 5, Cat 5e, Cat 6, and Cat 7 — allowing you to bridge short cable runs into a longer one while maintaining solid signal quality. Built with a compact, durable black ABS/PVC housing and nickel‑plated or gold‑plated copper contacts, the NW114 ensures stable, corrosion‑resistant connections and helps protect against crosstalk and electromagnetic interference (EMI) for up to Gigabit speeds (~1000 Mbps) and beyond. It’s compliant with common networking standards and can fit into wall‑plate installations or simple desktop setups, making it a practical, tool‑free solution for home, office, or workshop Ethernet expansion — ideal if you just need a quick and reliable way to extend your wired network without fishing new cable.
