Ethernet Splitter

If you have got a small office wherein you use multiple computers, you can use an Ethernet splitter to make a connection between computer networking devices, or computers through one cable, so as to share the internet connection among the computers. Let's consider a very simple scenario, wherein we have, in an office, 2 computers and 1 Ethernet jack with 1 Xbox and an HTPC. Now suppose you can't practically extend cables to the office from patch panel, the splitter will help you to connect these 2 devices.

With a little information on cable wiring and some patience, you can make your own splitter, by following the protocol. 1 Ethernet instrument will connect 2 or more computers, enabling communication between multiple devices. If you know about the basics such as routers, hubs, switches, you can make a splitter.

Devices Required

You need the following devices to make your Ethernet splitter.

• Approximately 3 feet long Ethernet cable scrap.
• RJ45 keystone jacks, 4 pieces
• RJ45 crimp plug, 2 pieces

You will require following tools such as:

• 110 punch down system
• RJ45 crimp equipment
• An adhesive such as a glue
• A knife

Procedure

Step 1: It is important to use the appropriate cable splitter, such as RJ45 1X4. Wire strip approximately an inch of coating from both the sides of cable.

Step 2: Next step is wiring scheme. After you strip the cable, you can notice 4 pairs of wires, each of which is given a color code. Untwist the existing wire pairs. You can make the wiring scheme as, beginning from the left,

• Green/white
• Green
• Yellow white
• Solid blue
• Blue white
• Solid yellow
• Brown/white
• Solid brown.

Step 3: Now make the jacks such as jack 1 consisting of:

• Solid blue to pin 2 jack.
• Blue white to pin 1 jack.
• Brown/white to pin 3 jack.
• solid brown to pin 6 jack.

And jack 2 consisting of:

• Green/ white to pin 1.
• Green to pin 2
• Yellow white to pin 3.
• Solid yellow to pin 6.

After you have punched down the 4 pairs, stick 2 jacks to each other. Now prepare one more splitter by following the same procedure.

Step 4: Connect 2 computers or devices to one splitter and connect the splitter to the RJ45 wall plate. Now plug patch plate to the other splitter and connect 2 cables with patch cables. The 2 links from the knob will turn on if you have done the connections right.

A splitter such as RJ45 1X4, can be used for using 1 common internet line between 4 network devices or computers. A splitter makes the use of cable types such as cat 6 cable, cat 5 cable or a standard Ethernet cable. There are 2 types of cables used. One is crossover cable and the other is standard patch cable, which enables connecting a computer with a switch or a router, whereas crossover cable links multiple computers without a switch or a router. In case of internet sharing or information sharing between multiple computers or network devices, a splitter serves as the best option. A splitter solves out multiple connection problems by approximately duplicating the ports by twice. Similar to a modem or a CPU, a plug is provided at one end of network splitter, which can be linked to the modem. The other end of the cable splitter has 2 ports which can be linked to different cables. Thus, if you want to double the number of systems getting Internet access, you can link the splitter to the modem.
