NEXUS CAT6A Coupler SFTP RJ45 10Gbps

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.

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.
