⚡ 10Gbps Speed 🛡️ SFTP Shielded 🔩 Gold-Plated Contacts 🔌 Female to Female Stop replacing entire Ethernet runs just because one cable is too short. This CAT6A SFTP RJ45 Coupler lets you join two cables together cleanly, keeping your network shielded, stable, and ready for speeds up to 10Gbps. Built with a shielded zinc-alloy housing and gold-plated contacts, this female-to-female keystone coupler snaps straight into standard wall plates and patch panels — no crimping, no re-terminating, no tools required. Just line up the two cable ends and you're back online. Specs at a glance Category CAT6A Max Data Rate 10 Gbps Shielding SFTP (Foil + Braid) Connector Type RJ45 Female to Female, Keystone Contacts Gold-plated Housing Shielded zinc-alloy Compatibility Cat5e / Cat6 / Cat6A / Cat7 Color Silver Why SFTP shielding matters Most budget couplers use unshielded plastic housings that leave your connection exposed to EMI/RFI interference from power lines, fluorescent lighting, and nearby cable runs. Over longer distances or in noisy electrical environments, that interference shows up as dropped packets and inconsistent speeds. This coupler uses SFTP construction — individually foil-wrapped conductors plus an outer braided shield, housed in a shielded zinc-alloy body. That keeps interference out at the exact point where two cables meet, so your join performs as reliably as the cable itself. Key features SFTP double shielding — foil + braid construction rejects EMI and crosstalk at the join 10Gbps-ready — built to CAT6A spec for high-bandwidth tasks like streaming, gaming, and file transfers Female-to-female keystone design — works with Cat5e, Cat6, Cat6A, and Cat7 cabling Gold-plated contacts — resist corrosion and keep the connection stable over time Shielded zinc-alloy housing — stands up to daily handling in offices, racks, and home setups Tool-free install — snaps into standard wall plates and patch panels in seconds No re-crimping required — extend a run instantly instead of replacing the whole cable Ideal for Extending a run that came up just short of the wall plate or patch panel Office and commercial LAN installations Server closets and structured cabling projects Home network wall-wiring and patch panel repairs Gaming setups and 4K streaming installations needing a clean, shielded join Frequently asked questions Will this coupler slow down my network? No. As a shielded CAT6A-rated coupler, it's built to pass 10Gbps signals without adding meaningful loss, provided both cable runs and the coupler are properly seated. Can I use this with CAT6 or CAT7 cable, not just CAT6A? Yes. The female-to-female RJ45 keystone design is compatible with Cat5e, Cat6, Cat6A, and Cat7 cabling. You'll operate at whichever category's speed is the lower of the two cables joined. Do I need any tools to install it? No tools needed. It's a tool-free, snap-together design that drops into standard wall plates and patch panels, or can be used as a standalone inline joiner. Why choose a shielded (SFTP) coupler over an unshielded one? Shielding protects your signal at the exact point where two cables meet — often the weakest link for interference in a run. If any part of your cable path is shielded (S/FTP, F/UTP, etc.), using an unshielded coupler breaks that shielding continuity and can reintroduce EMI/RFI issues.
