Y.D.F RJ45 Coupler, Network Coupler Ethernet Connector, for Cat7/Cat6/Cat5e/cat5 Ethernet Cable Extender Connector - Female to Female, Black

Installed security camera system in our church. These were needed to connect 2 cables together for some long runs. Worked well and we have spares. Fair price and arrived quickly.

I noticed a few reviews saying that these limit your speed or that the reviewer couldn't get more than 10Mbps. I'm not sure what issues they had, but these work great for me! I had to extend cables terminated in a cabinet (cables ran a part of my new house build) - I extended these to a wall mount rack (about 15 feet). These worked perfect - no errors, 1Gbps, POE. These are very durable and provide a solid connection to the RJ45 connector - no possibility of bumping and accidentally disconnecting these. If people are having issues with connection speed after using these, your issue is most likely your existing cabling. Perhaps you are extending and going beyond the recommended distance for the cable type (CAT 5). Perhaps the cables you are using or connectors are loose or causing a poor connection. I actually measured the loss through these couplers - it is very minimal - but there is some loss as with any connector or couple. So, if you are already at or beyond the recommended distance for your cabling type, this could put you over the edge.

I had a camera system I was replacing. the previous installer had used Cat 5E cables, but had used them for an analog camera system, and cut the wires to length to reach a wall mounted power supply, which was about 3 feet from the recorder. so when I went to replace the camera system with a modern IP camera system, I had a few wires that were too short to reach the New NVR. I ad two choices, use some keystones, terminate them and use a patch cable, install a patch panel and then patch cables, or simply use some couplers. After reading some reviews, and finding these were a good price, I ordered and could not be happier. these feel super sturdy, and worked without issue at all. POE power to the cameras goes perfectly and does not degrade the signal at all. These are worth it.

I always make sure I have a few of these in my kit that I use when testing networks. Some times I want to add another 50 feet of cable so I can sit at a desk instead of sitting on the floor. I just add one of these and boom, I can sit somewhere comfortable. Cheap ones cost the same money as these and I very impressed with the quality of these units. So far they have worked great but I have only had them for a few weeks.

Best on the market! We use it for many solutions and applications! CCTV and more!

Good quality and fits perfect

It work great as a Ethernet Coupler, the speed is good and would buy again for sure.

Good seller and products.

Handy everyday item to extend RJ45 wiring.
