Equip Cat6 Shielded Modular Inline Coupler — RJ45 F/F
Cat6 shielded250 MHz · 1 Gbit1:1 straight-throughPoE++
The Equip 121179 is a fully shielded Cat6 inline coupler with two RJ45 jacks that joins two patch cables into one longer link. It is used to extend Cat6 patch cords in server rooms, network closets and offices that need consistent Gigabit connections.
The shielded housing protects the joint against electromagnetic interference, gold-flashed contacts keep the connection reliable, and the 1:1 pin configuration passes every pair straight through. Equip specifies 250 MHz bandwidth and 1 Gbit Ethernet, with PoE, PoE+ and PoE++ support for powering cameras, access points and phones through the joint.
Before you order: For Cat6 performance, use Cat6 (or better) patch cords on both sides and keep the whole channel within 100 m.
What's in the Box
- 1 × Equip Cat6 shielded modular inline coupler, RJ45 F/F (121179)
- No cables included
What It Means in Practice
- Extend a patch cord that is too short instead of replacing it.
- Keep shielded cords shielded across the joint — useful near power cables and machinery.
- Pass PoE through the joint to IP cameras, access points and VoIP phones.
- Gigabit-capable joints for desks, printers and network closets.
What Will Not Work
- It is not a splitter and does not create a second port.

Frequently Asked Questions
Can I join unshielded cables with it?
Yes — RJ45 plugs fit regardless of shielding; you just lose shield continuity on unshielded sides.
Does PoE pass through?
Yes, Equip lists PoE, PoE+ and PoE++ support.
Can I use it for 10 Gbit?
It is specified for 1 Gbit. For 10GBase-T choose the Cat6A version, Equip 221171.
