Digitus CAT 6 Shielded Modular Coupler — RJ45 to RJ45, Pack of 2
CAT 6Shielded8P8C 1:12 pieces
The Digitus AT-AG-8-8-C6S-2 is a pack of two CAT 6 shielded modular couplers — each one an RJ45 socket on both ends, wired 1:1 (8P8C) — for joining two patch cables into one longer link. It is for IT staff and installers who need to extend a cable that turned out too short, or bridge two patch cords without re-terminating.
Each coupler has a shielded design with a tinned bronze shield, phosphor-bronze contacts with nickel and 0.5 µ gold plating, and Digitus rates them for at least 750 mating cycles according to ISO/IEC 11801 and IEC 60603-7-5.
Before you order: The shield only carries through end-to-end when shielded cables with shielded plugs (S/FTP, F/UTP) are used on both sides. With unshielded (U/UTP) cords the coupler still works, but simply as an unshielded joint.
What's in the Box
- 2 x CAT 6 shielded modular couplers, RJ45 socket – RJ45 socket
What It Means in Practice
- Extends a link by joining two patch cables — e.g. 5 m + 3 m when an 8 m cable is not to hand
- Keeps the 1:1 wiring: both cables must be standard straight-through patch cords
- Every coupler adds a connection point to the channel; for a permanent link a single cable of the right length is the cleaner solution
- Two in the pack: one for use, one spare — or two extensions at once
What Will Not Work
- It is not a keystone or panel-mount module — it hangs inline on the cable
- Not a crossover adapter: pin 1 goes to pin 1
- Not a splitter: it cannot share one cable between two devices
- Not for outdoor use — choose an IP67 waterproof coupler for outside runs

Frequently Asked Questions
Does a coupler slow the network down?
A CAT 6 coupler is part of the CAT 6 link, but every joint adds loss. For short extensions in normal office links it is fine; keep the total length within 100 m and avoid chaining several couplers.
Can I use it with Cat5e or Cat6A cables?
Yes, the RJ45 interface is the same. The link performs at the level of its weakest component.
Does PoE pass through?
The coupler is a 1:1 passive connection, so all eight wires pass through — PoE devices see the cable as one link.
Singular Expert Insight · Buyer's Guide
A coupler is the quick fix for a cable that is just too short. If the joint will stay permanently, it is usually better to replace both cords with one
shielded patch cables of the right length — fewer connection points, fewer things to fail. Keep the spare in the network toolbox.
✓ Buy it if you need to join two patch cords quickly, especially in shielded CAT 6 installations.
✕ Skip it if you need a wall or panel module (choose a keystone) or the joint is outdoors.
→ Also consider a single patch cable of the right length, or the Lanberg IP67 waterproof coupler for outdoor runs.
