Ideal Industries 85-356 – Frequently Asked Questions

1) Will an Ideal 85-356 RJ45 coupler work with CAT5e patch cords, or only CAT6?
The Ideal 85-356 inline coupler takes any standard 8P8C modular plug, so CAT5e cords plug in and pass traffic fine. The coupler itself is built to Category 6 performance up to 250 MHz, so it won't hold back a CAT6 channel, but a CAT5e cord on either side sets the ceiling for that run. Match the cord to the performance you need.
2) Can I use an inline RJ45 coupler to repair a cut Ethernet cable instead of re-terminating it?
Yes, that's one of the jobs the 85-356 coupler is built for. Terminate each cut end with a standard 8P8C plug and join them through the coupler, no punch-down block or specialty termination tool needed beyond your crimper. Retention tabs on both ends hold the plugs so a bumped cable doesn't drop the link. Test continuity with a cable tester after the splice, and support the coupler in a tray or clip so the cable weight isn't hanging on the connection.
3) Is the Ideal 85-356 coupler shielded, and can I use it on a shielded CAT6 run?
The 85-356 is an unshielded coupler with a white thermoplastic housing. On a shielded (F/UTP or S/FTP) run, an unshielded coupler breaks the shield continuity through the joint, so if the run was specified shielded for noise reasons, this is the wrong part for it. Use it on standard UTP CAT6 and CAT5e cabling.
4) Will an inline coupler slow down my gigabit or 10-gig network?
For gigabit, no. The 85-356 is rated to full Category 6 specification up to 250 MHz with gold-plated contacts, so it passes a 1000BASE-T link without measurable loss. Understand what it does to the channel, though: every coupler is an extra mated connection, and TIA/EIA-568-B channel rules allow a limited number of connections in a permanent link. Two couplers in series on one run is where installers start seeing test failures. For a certified 10-gig run, a permanent link with no inline joins is the safer build.
5) Can I run an Ideal CAT6 coupler in an unconditioned space like a garage, attic or outdoor enclosure?
Operating range on the 85-356 coupler is -10 C to +60 C (about 14 F to 140 F). That covers most garages, riser closets and equipment rooms. It's not a sealed or weatherproof part, so in an outdoor or wet location it belongs inside a rated enclosure, and a black attic in a hot climate can push past the top of that range.
6) Should I use an RJ45 coupler or a keystone jack and faceplate to extend a network drop?
Depends on whether the joint is permanent. A coupler like the Ideal 85-356 joins two already-terminated patch cords with no tools, which is what you want for a field repair, a temporary extension, or a run inside a rack or cable tray. If the joint is a wall termination that people will plug into and unplug from every day, a punch-down keystone jack in a faceplate or patch panel is the right build: the solid-core cable lands on IDC contacts instead of hanging on a plug, and it takes the wear. Couplers are for cord-to-cord, jacks are for cable-to-cord.
7) Can I use an Ideal RJ45 coupler on a PoE camera or access point run?
Yes. The 85-356 passes all eight conductors straight through on 8P8C contacts, so PoE and PoE+ power carried on those pairs passes with it, which is why it shows up on IP camera and access control runs. Keep it out of the weather and inside the camera housing or a rated enclosure, and remember the coupler adds a mated pair of contacts to a run that is already carrying current, so keep the plugs fully seated.
8) Does the Ideal 85-356 coupler mount to a wall plate or panel, or is it loose inline?
It's a loose inline coupler, a compact barrel that sits in the cable path rather than snapping into a keystone opening or mounting to a box. Plan to hold it in a cable management channel, tray, or a tie point so the connections aren't carrying cable weight, and label both ends for whoever troubleshoots it later. If you need a coupler that clips into a faceplate or patch panel opening, you want a keystone-style feed-through insert, not this part.
9) Is the Ideal CAT6 inline coupler UL Listed for commercial building installation?
Yes, the 85-356 is UL Listed for commercial and residential installations, and it meets TIA/EIA-568-B Category 6 specifications. That combination is what facility and institutional specs usually call for on datacomm accessories. Note it is not a plenum-rated component claim; where a plenum space is involved, that requirement falls on the cable and any enclosure.
10) What color is the Ideal 85-356 coupler and does it come in any other finish?
White, in a thermoplastic housing, and 85-356 is the single model, so white is what you get. It blends with standard white faceplates, raceway and cable management in office and classroom spaces. In a rack or an equipment room where nobody sees it, the color is irrelevant to performance.
