🧠🔗 Cat6 • Cat6 Ethernet Adapter

This coupler features two RJ45 female ports, allowing you to connect two male-ended Cat6 Ethernet cables together. It’s used to extend cable length, reroute network paths, or adapt modular setups without re-crimping or replacing cables.
 
🔧 Coupler Format
Connector Type: RJ45 Female ↔ RJ45 Female
Cable Compatibility: Cat6 (also backward compatible with Cat5e)
Form Factor: Inline or keystone block
Shielding: Available in shielded and unshielded variants
Pin Mapping: Straight-through—no crossover or signal conversion
Speed Support: Up to 1 Gbps (some support 10 Gbps with short runs)
 
🖥️ Compatible Devices
💻 Desktop PCs, laptops, gaming consoles
🌐 Routers, switches, modems
🖥️ Network printers, IP cameras
🧰 Patch panels, wall jacks, keystone plates
🏢 Structured cabling in offices or server rooms
🧪 Ethernet test rigs and diagnostic setups
 
✅ Common Uses
📏 Extend Ethernet cable runs without re-crimping
🧩 Patch across rooms or modular network zones
🛠️ Reconfigure network layouts on the fly
🧯 Replace damaged cable segments temporarily
🧪 Test network continuity with modular setups
 
🧠 Signal Format Notes
Protocol: IEEE 802.3 (Ethernet over twisted pair)
Pins Used: 8P8C (standard RJ45 layout)
No Power: Passive device—no PoE passthrough unless rated
No Conversion: Does not alter signal type or voltage
❗ Performance depends on coupler quality and shielding
 
⚠️ Things to Watch Out For
📏 Total cable length must stay within Ethernet spec (≤100m for Cat6)
🧯 Cheap couplers may introduce signal loss or instability
🔌 Only works with male-ended RJ45 plugs—check connector gender
🧪 Test with known-good cables before deploying in critical setups
🛡️ Use shielded couplers in high-interference environments
 
🛠️ Quick Tips for Beginners
🔍 Identify RJ45 by its 8-pin rectangular layout
🧭 Use female/female coupler to join two male Cat6 cables
🧰 Keep one in your toolkit for quick network extensions
🧪 Test with a laptop or network tester before final install
🧼 Store in anti-static bag—metal contacts are sensitive
