Review: Needed a couple of inline couplers for extending Ethernet runs, and these did exactly what they’re supposed to do. The connections are snug, the latch holds tight, and I’m getting full speed through them with zero drop in performance. No wiggle, no random disconnects, no cheap-feeling internals. They’re rated for everything from Cat5e through Cat8, and so far they’ve handled high-speed traffic without any issues at all. Simple, reliable, and way better than some of the flimsy couplers I’ve used in the past. If you need a clean, low-profile way to join two cables without sacrificing performance, these are a solid buy. Would get them again without hesitation.
Review: Work great. No issues using them. No failures, loss of speed or data.

## Questions & Answers

**Q: What network cable is it suitable for?**
A: I've even used this to extend my RJ-45 console cable from the 6 foot console adapter adding a 14 foot cat6 to reach the Wireless Access Point in the ceiling.  Needed to do this to factory reset the WAP and didn't want to remove 5 of them, take to the network closet to do the work, and then remount them.  Was just easier with the extra length.  So they prove useful beyond network extending and good for console extending as well.  *The fun part was getting down from the ladder within the 10 second boot sequence before the "interrupt boot" prompt that's up for only 2 seconds.

**Q: Working for Cat8 ?**
A: Supported. But the network speed should not reach the speed that cat8 can achieve.

**Q: will it work with cat6a with no speed loss?**
A: Yes, it can be supported. you can try. If you have any questions, you can contact me through the contact customer service in the order. I will provide you with after-sales service.

**Q: I need to extent a cat 6 in t-568b standard, do i need to invert the cable of one end or this adapter will correct do the job?**
A: No, you should not need to invert your cable.  This RJ-45 Coupler provides a 1:1 wire match.
