Digitus Cat6 Shielded Modular Coupler — RJ45 F/F
Cat6 shielded2 × RJ45 female1:1 straight-throughMetal housing
The DIGITUS AT-AG 8/8 C6S is a shielded Category 6 inline coupler that joins two RJ45 patch cables end to end, so you can extend a cable run or bridge a short gap without re-terminating anything. It suits installers, IT staff and home-office users who need a quick, clean extension of an existing Ethernet connection.
Both sockets are wired 1:1, so pin 1 on one side meets pin 1 on the other and the link behaves like one longer patch cord. The metal body carries the cable shield from one side to the other, which matters when you are joining shielded (S/FTP or F/UTP) cords in an environment with electrical noise.
Before you order: Every coupler adds a connection point to the channel. Keep the total length of cable plus coupler within the 100 m Ethernet limit, and use Cat6 or better cords on both sides if you need Cat6 performance.
What's in the Box
- 1 × DIGITUS Cat6 shielded modular coupler, RJ45 female to RJ45 female (AT-AG 8/8 C6S)
- No cables included — use your own RJ45 patch cords
What It Means in Practice
- Extend a patch cable that is a little too short to reach a desk, printer, camera or access point, instead of buying and running a new longer cable.
- Join two shielded cords and keep the shield continuous through the metal housing — important near motors, lighting ballasts or power cabling.
- Straight-through 1:1 wiring means it works with standard T568A and T568B cords alike; it does not swap pairs or create a crossover.
- A temporary fix for a damaged cable: cut out nothing, just connect two good lengths together while a permanent run is planned.
What Will Not Work
- It is not a splitter: you cannot connect two devices to one cable through it, and it will not give you a second network port.
- It does not upgrade a link — a Cat5e cord on either side keeps the whole connection at Cat5e level.
- It is not a keystone module and does not snap into a patch panel or wall outlet.
- Not rated for outdoor or wet locations; the published operating range is −10 °C to +60 °C with no IP rating.
Key Features
Shielded metal housing
Nickel-plated bronze shielding in a metal body passes the cable shield straight through the joint.
Gold-plated contacts
Phosphor-bronze contacts with nickel and 0.6 µm gold plating for stable contact resistance.
Durable sockets
Specified for at least 750 mating cycles, so frequent re-plugging is not a concern.
1:1 pin assignment
Transparent connection: no crossover, works with any standard RJ45 patch cord.

Frequently Asked Questions
Can I join an unshielded cable with it?
Yes. The RJ45 sockets accept unshielded plugs too; you simply do not get shield continuity on that side.
Will it slow my Gigabit connection?
A Cat6 coupler between two good Cat6 or Cat5e cords supports Gigabit Ethernet, as long as the total cable length stays within 100 m.
Can I use two couplers in one run?
It works, but every joint adds loss. For a permanent installation, one continuous cable or a proper patch panel is the better choice.
Singular Expert Insight · Buyer's Guide
A coupler is the fastest way to extend an existing cable, and the shielded metal version is the one to choose when your cords are shielded or the cable passes near power lines. If you need longer cords instead, browse our
network cables.
✓ Buy it if you need to extend or join shielded or standard Cat6/Cat5e patch cords quickly.
✕ Skip it if you need a 10 Gbit Cat6A link end to end — choose a Cat6A coupler — or a permanent wall installation, where a keystone outlet is cleaner.
→ Also consider a longer Cat6 patch cable, which removes the joint completely.
