An RJ45 joiner (commonly called an inline coupler or adapter) is a small networking device that connects two Ethernet cables with RJ45 plugs together. It features two female ports and is used to extend cable reach or bridge separate network segments without buying a brand-new, longer cable.
Key Features & Configurations
- Inline Couplers: Portable, plug-and-play devices designed to temporarily or permanently extend cable runs. They generally support standard Ethernet speeds up to Gigabit or 10-Gigabit, depending on the model.
- Keystone Couplers: Designed for fixed installations and snap directly into wall plates or patch panels.
- Weatherproof/Industrial Joiners: Built to withstand harsh environments. For instance, heavy-duty joiners offer dust- and moisture-proof seals (like IP68 ratings) for use in garages, factories, or outdoors.
Compatibility
Most modern RJ45 joiners are backward compatible and support standard Ethernet categories like Cat5e, Cat6, Cat6A, and Cat7.
