Monoprice 8P8C RJ45 Straight Inline Coupler, Beige

All I had were ethernet cables, either too long or too short. Not wanting to buy or make new cables, using these connectors and shorter cables was the solution.

this item came in so handy just right for my needs

I purchased 60 of these to use with my specialized lighting controllers for the holidays. Every yea, I'd have to unscrew a controller lid to access the cat5 cable jacks to install the cat5 cables that would then run to another controller in daisy-chain fashion. There has to be a better way, because I couldn't pre-install the cat5 cabling for data transmission until I placed the controller and mounted it. Then I'd know how long the cat5 cable needed to be to get to the next controller, and so forth, until all of my controllers were interconnected. Well with dozens of controllers, and each having two cat5 jacks, and each lid requiring the removal and reinstallation of 8 screws was a real pain in the backside, especially if having to do this on a ladder! So then I remembered, Monoprice may have just the item I need, they sure did, the Monoprice 8P8C RJ45 Straight Inline Coupler, in Beige would be just what I needed, along with a few 1' cat5 cables to have the cat5 cane come from inside the controller box and the other end outside where I could use 2 couplers, since each controller has two cat5 jacks for data flow. After opening every single package, yes, all 60, individually packed, I tested all the short cat5 cables and all 60 couplers, to be sure they were good., they all tested 100% using a cat5 cable tester, Cat5 Tester ? 1' cat5 ? coupler ?1'cat 5 ? back to Cat5 tester. So I completed the modification of all my controller boxes using two 1' cat 5 cables in green to match the controller boxes and 1 coupler per cat5 exiting the controller box. These are being used outside and so far have held up to our usual Florida Thunder and rainstorms. They haven't wavered in the least, I know they may not be outside rated, but I've had about 10 of these outdoors now since I received them, as a few of these control exterior year-round lighting in my yard and handicap ramp. Even in the harshest and hardest, windy rainstorms, these have kept working. It may not be exactly what these couplers were designed for, but they're working out so far 100%, the lights have stayed on in the most adverse weather we get. Why did I buy a lot more than I actually needed? As I was taught many years ago, always have more than you need, that way if one goes bad or something happens that it no longer works, you have plenty of spares to keep things working! Yes, I'd highly recommend these couplers. They are sure going to save me a ton of time during my Christmas Display and other holiday lighting times, because now, my controllers are plug and go, which will be a great time-saver in both set-up and tear down. Thank you Monoprice! Would have loved to post a photo of how these look in my current setting, but unfortunately I don't own a camera or video-recorder.

Works great, I connected a 20 feet CAT5 to a 15 feet CAT5 cable. No detectable drop in speed. Cheap fix to extend cable.

its a RJ45 Coupler, and it works fine at 1000mbps speeds, and its sold at monoprices low low prices.... what more do you need to know?

Needed to extend some cat 6. Has been working flawlessly

Just plug a cable into each end and you're good to go.

Can't beat the price. I taped two Ethernet cables to the coupler to firmly hold everything in place.

This worked fine for 3 years, then started to have sporadic issues. It started to fail and my Ethernet connection stopped working. The cable and other connectors were fine - this was the culprit. It was hidden behind a wall so this was difficult to diagnose and fix

It works great. Better than the cheap, unreliable ones.

Connected cables do not carry Ethernet signal. This connector is useless.
