Now, let’s move on to the cat5-wiring-diagram for home network wiring. It sounds complicated, but it’s actually easier than phone system wiring. Some people tell me that with all the home networks with wireless routers available today, running cable throughout the house is becoming obsolete.

Trust me, as a digital communications engineer, you don't want to use wireless systems if you have neighbors that live within a half mile of you.It’s a good idea to put data ports in every room with the exception of bathrooms and storage rooms.
This is called an RJ45. Networks use CAT5 cable with a connection that is a little larger than a normal phone connection. A phone connection is an RJ11 and it will fit into an RJ45 port.

Networks are the same as phone lines in many respects. The old method for wiring networks as well as phone systems was in a daisy chain, that is, out of one computer into the next computer on down the line. The problem is when one computer goes down it pulls all the others behind it down also.It didn’t take long to figure this one out. Almost all cat5-wiring-diagram networks now use a Hub. This is where each data port is a dedicated line running back to the hub. Most modern homes are built with an accessible “Distribution Center”.
This is typically located near the breaker box. The only reason for this is just to keep the utility panels together as a matter of convenience. It’s a good idea to have the distribution center contain all communication wiring.

For example, I would put a junction box for the phone systems in there. Also, I would put a network hub and a TV hub for my coax cables. So all the CAT5, Coaxial cables, speaker wires, and intercom wires will start from the distribution center and then branch off to all the different rooms.

It is always a good idea to run all the communication cables together. They’re easier to manage that way and you can keep everything organized all in one strand. The terminations for the RJ45 connectors are color-coded making it easier to keep the wiring order consistent.
The wires each fit into a slot that cuts through the plastic coating and make a solid connection with the copper wire inside.

You’ll need a special tool for terminating RJ45 network cable.Terminating CAT5 is really easy, but it takes a little practice. You’ll want to cut the sheathing off about an inch down. Next, you will cut all the wires so they’re even. There is a cutter on the crimper tool.
After lining up the wires in the correct order, you take the connector and slide it over the wires with the tab down. They should each fit into each of the eight holes and you will be able to see if they’re straight or if they’re crossed anywhere.

The crimper will have a slot for RJ-11 connectors and RJ-45 connectors. Slide it in the RJ-45 slot and crimp it down tight.

There is a high potential of error when terminating CAT5, so you may want to buy or rent signal testers and test the cables before you close things up. Line testers will test all eight channels on RJ-45 connectors and they are also useful with regular phone line circuits.
