There may be times when you need two Ethernet cables. There will be a variety of reasons behind this, with the most common being because you need both phone and broadband. Unfortunately, most of us aren’t technical wizards who know the insides and out of every cable. I mean, you wouldn’t be on this blog if did! Fortunately...
There may be times when you need two Ethernet cables. There will be a variety of reasons behind this, with the most common being because you need both phone and broadband. Unfortunately, most of us aren’t technical wizards who know the insides and out of every cable. I mean, you wouldn’t be on this blog if did! Fortunately for you though, we have a solution that allows you to use one Ethernet cable to power two connection. They’re known as RJ45 economisers and they are more common than you might think.
Our RJ-MOD is an economiser cable adaptor that carries two connections over a single port and outputs the same two connections to different locations. This is the perfect solution to adding extra ports to your wall sockets.
To get the basics out the way, I’ll go over briefly what a RJ45 cable is. If you already know, you can skip this paragraph. A RJ45 cable is (in layman’s terms) an Ethernet cable. They allow for the transfer of data along a single wire, allowing for broadband usages such as internet and landline phones. They are some of the most common cables you’ll see in a house but are not really understood by a lot of people despite their commonality. They have an 8P8C design (8 pins) and this is what allows them to power to connection from one port.
The Economiser Part
So you know what a RJ45 cable is, great! Now you can begin to understand how an economiser works. An economiser is basically a way to get two Ethernet connections from one port/socket. They are these little blocks that allow for the use of all the pins in the cable, which let two connections to simultaneously travel through the cable. There are a range of economisers you can use depending on the connection you need. In fact, there are three. You can get economisers for data/data, data/voice, and voice/voice connections. Putting it simply, there are economiser that allow for internet/phone, internet/internet and phone/phone. Still following me? If you are, great because these variations have different colour schemes as well. Data/data economisers have grey boots, data/voice have green boots and voice/voice economisers have red boots.
Fast Ethernet or Gigabit Ethernet
It should also be noted that RJ45 economisers only work with fast Ethernet connections because of the pin layout. Fast Ethernet only uses 4 out of the 8 pins available in RJ45 cables, allowing for two spares to pass concurrent connections down. If you are still on a gigabit network, unfortunately, you cannot use economisers to slip connections because there are not enough pins. Gigabit cables use all 8 pins.
Couplers and Patch Panels
The way you set up your economisers is going to vary depending on where you are and the situation. If you are using a patch panel in an office you will not need a coupler to create a female end. The Ethernet cable will go straight into the panel and then the economiser can be plugged in on the other side. With standard home setups, however, you will need a coupler to create a female end, allowing to plug the economiser into the system.
RJ45 economisers are a very useful tool that allow you to split Ethernet cables to power to two connections from one port. They are used in every home to power multiple objects and are not too difficult to understand. If you need to split your Ethernet connection, don’t call your technician. Purchase an economiser and get the job done yourself!
