iwillink5-Pack Shielded Cat6 RJ45 Inline Couplers, Female to Female Ethernet Coupler, RJ45 Coupler for Cat6/Cat5e/Cat5 Ethernet Cables, Ethernet Extender Adapter in Silver

Good quality ethernet coupler. My Fluke networks certifier is an older unit, but it's more than capable of pushing Ethernet equipment to it's limits. It passed by a close margen, but for a budget connection, that's good enough!

I opted for these RJ45 connectors as they incorporate a metal shield. I disassembled one connector, here’s what I found, the metal is stainless steel (non-magnetic) and not copper. Shielding is 100% on all sides except for the RJ45 jack ports. The pins are gold plated, terminals are wave soldered to the board. There was minimal solder at the connections but all 10 passed a sequenced continuity test (all 8 pins good electrical connections), in service speed test, it performed flawlessly, no data loss, no degradation in speed and no interruptions in service. The circuit board was conformally coated (excellent for moisture protection) and fit perfectly into the sturdy high tolerance plastic housing, the metal shielding locked together extremely well. It was in fact, very difficult to disassemble due to tight seams and clean well formed bends. Moreover, any vendor that goes to extent to spec out insertion and retention forces and spends the money to manufacture to this level and tolerance, at this price point, this is a no brainer. Buy it!

I've used several of these around my computer lab. They work great. Lets me string several cables together so I don't have to rely on wireless. I was expecting to see some type of slow down by using these but it is very minimal.

Necesitaba unos de mejor calidad que los que conseguia en los comercios donde vivo, vi estos y me parecieron geniales, funcionan bien.

Two couplers come in an order and they fit nice and tight with my short cords. With no connection issues I can plug in and string the cord out of the way and around the door to reach my PC ABSOLUTELY LOVE IT! Definitely worth it & will be buying more for the other rooms.

Well made little Ethernet couplers. i love to keep some on hand, so many times I just a need a couple feet more and just have shorter cables on hand. Super simple to use, just plug in a cable on either end. Metal housing and gold plated contacts. No issues with t100 or t1000 speeds. I am old school and prefer wired networking and these couplers are indispensable.

Connected two cables, and didn't see any drop in speed. Highly recommended!!!

Added a different camera and wanted to reposition about 10 feet further away and did not want to rerun ethernet all the way back to switch. This was a perfect way to extend at short distances. I only needed 1 but happy to know I have extras if the need comes up

Makes things easier than making my own!
