Hi again! This is Sebastien for www.CableOrganizer.com. Today I want to show you how this beautiful product works. This is the RJ45 Combiner/Splitter. This is a great product that can make your life so much easier; the only problem is that people are usually confused on how it works.

Let me explain it to you a little bit better. Now I need your imagination. Look at this; imagine there's a computer in one room. This is a typical network installation. The computer is connected to a wall plate. Behind the wall there's a cable running all the way to another room. From that room the cable comes out and goes to a switch or router.

Now, what people think the RJ45 Combiner/Splitter does is work as a hub. This means in the room they want to add another computer. What they're going to do is they're going to plug the RJ45 into the wall plate and they think that it is going to split the signal in two and then they can plug in two computers.

This is not quite how it works. Let me show you. If you want to add another computer then, yes, you're going to have to plug one of the RJ45's on one end. You're also going to have to add another RJ45 one on the other end.

What this does is that on one end the RJ45 is going to combine two signals into one cable and at the other end a different RJ45 is going to split the signal into two other cables.

The same as we did on the other side what you're going to do here is to connect two cables to your switch or router and you're going to combine those two into one signal into this cable.

What's the advantage of this? Well it's pretty clear. You don't have to run another cable between the two rooms. That can save you a lot of time and a lot of pain because it's never easy. This is how it works.

This is Sebastien for www.CableOrganizer.com, Thank-You.

I have my cable running to the back of my modem and that connected to the back of my router and my router to a xbox. Can i use this to split coming out of the back of my router to connect two xboxs?

@mindfull777 You would need to have a second cable plugged into the router, then use one of the splitter/combiners to "combine" the signal into one cable and then split the signal with the other splitter/combiner just before the two xboxs. Or you can try either a switch or just have a second cable go from the second xbox directly to the router.

appreciated,i couldnt figure out why only one socket worked

@klwc Unless you know for a fact that the first splitter is a splitter/combiner, then you may not be able to combine the two signals. Only using a pair of splitter/combiner will allow you to combine the two signals over the single cable, and then split them back for the two computers.

@CableOrganizers I have a pair, one connected with to cables to the computer and the other splitter connected into 2 computers. I know its a splitter, but i don't know if its a splitter/combiner. If you search "rj45 splitter" on google images you will see it on the 4th picture.

@Ridnarhtim That is the basic idea behind the splitter/combiner. Due to the amount of confused people, we are planning to re-shoot this video that will better explain the concept and hopefully clear up most of the confusion. Have you tested all cables, connections, jacks? Is either computer connecting?

[CableOrganizers]

@klwc If you are just using a regular rj45 splitter and not the splitter/combiner in both spots you may not get the same results. The RJ45 Splitter/Combiner only work in pairs.

[Ridnarhtim]

@CableOrganizers Okay, I am so confused. My understanding of these splitters is that you have 2 ethernet cables from 2 separate ports in the router going into the splitter. Then, you have one long ethernet cable going across your house to the other splitter. From this splitter, two more normal ethernet cables go out, one to each computer.

So the setup is (Router) ==(Split)------------(Split)== (2 computers)

This is not working for me, but that's how I interpret what you're saying in the vid...

[klwc]

@CableOrganizers Not exactly. I get an error if i post a link on here, so if you search on google images, "rj45 splitter" you will see my splitter on the 5th image (it looks like a phone splitter but it isnt)

In the first i have to cables to the router, on the 2th 2 computers but in between

one large cable connecting one to the other.

[CableOrganizers]

@klwc So if we understand you correctly, there are two cables coming from the router into one Splitter/Combiner, then there is the single large cable, and then the second Splitter/Combiner which the two computers are connected to, but you connected a socket to the splitter instead of the cable. Do you need the extra rj45 socket or have you tried with just the cable directly to the Splitter?
