Complete Guide To CAT 5 and 6 Cables, Their Advantages And Applications

Cat-5 cabling is short for Category 5, and refers to computer network cables, that are also called Ethernet cables. They consist of four twisted pairs of copper wire that are connected with RJ45 connectors that handle speeds of up to Location: W. 8 Mile Rd, Farmington, The four wire pairs in a CAT-5cable are distinguished by the color of their insulation. The four colors are (in order) blue, orange, greenand brown. Thus, when refering to the "second pair" of wires, it is the orangepair. Regular phone cable consists of two untwisted pairs, each with wires.

This page discusses the wiring how to cut out stencil these services. The specification defines the conductor size, insulation quality and wire twists, plus a multitude of performance characteristics.

CAT-5 cables have 4 wire pairs, making a total of 8 wires. Each pair is twisted together you've probably heard the phrase "twisted pair" before to reduce signal interference. The biggest factor car5 the catagory specifications is the number of twists per linear unit. The more twists, the greater the signal integrity. Data signals are sent over the wire using a differential method. With tighter twists, any interference received by the cable is more likely to affect both wires in a pair equally, resulting in no change in wiers difference between them.

This allows greater data capacity over longer distances. The tighter twists also suppress noise created by the cable because the magnetic field from one wire is canceled by it's mate, making it less prone to interfering with other cables.

When terminating data cables with crimp-on connectors or at punch-down terminalsit is important to how to install xp on windows 8 the pairs as little as possible 1 cm. Some ill effects wirds tighter twists is they make the cable more stiff and brittle. CAT-5 cabling can come with either "solid" or "stranded" cores.

Each wire core in "solid" CAT-5 contains a single 24 gauge wire. Each wire core in "stranded" CAT-5 is made from several thin strands. The solid cable is stiffer and less suseptible to moisture contamination, making it the choice for in-wall wiring. The stranded cable is more flexible, less suseptible to fatigue from wnat bending and should only be used for cables no longer than 3 meters, making it the what wires are used in cat5 for patch cables the cables connecting the wall jack to equipment.

The connectors that are crimped how to make an extension wire the end of CAT-5 are whag meant for either solid or stranded cable though some will work with bothso be sure you get the right kind for your cable and make sure they are CAT-5 rated. CAT-5 cabling can also come "shielded" or "unshielded".

All the wire pairs in "shielded" CAT-5 are contained in a wire-braid tube called a "shield". This further protects the wires from outside interference and reduces the amount of fat5 that can escape the cable. We recommend unshielded CAT-5 for home what is proair inhaler used for, and many equipment specifications also call for unshielded cables.

Another term you will hear a lot while shopping for CAT-5 cable is "plenum". The term "plenum" refers to the fire rating for the material making up the outer jacket of the cable. Plenum rated material does not release toxic fumes in the event of a fire.

Many building codes require the plenum for commercial installations but not for residential installations. Commercial buildings typically run cable through drop ceilings, and since the drop ceilings are also used for air circulation this is called a "plenum space" there is the potential to distrubute fumes during a fire.

Residential homes typically use sealed ducts to distribute air so there is no real chance for contamination an exception to this is running wires in the return air space, which is typically not ducted. Also, homes are evacuated faster than commercial buildings, so the danger of a hazardous exposure to fumes is inherently less. With all the PVC already in most homes, in our non-expert opinion it is not worth the price difference to get plenum sometimes twice as expensivebut that is a decision you should make how to make a song louder yourself after more carefull and thorough research.

Refer to your applicable building codes regarding plenum cables before you make any installations. There are other practical differences between CAT-5 cables.

Some have a fiber filament that takes some of the tensil strain off the wires. Others have easier-to-distinguish colors on the wire pairs. These are just a few and it depends on the brand you buy.

The four wire pairs in a CAT-5 cable are distinguished by the color of their insulation. The four colors are in order blueorangegreen and brown. Thus, when refering to whst "second pair" of wires, it is the orange pair. However, we will recommend CAT-5 for phone and concentrate there.

Strictly speaking, each colored wirse consists of in order a white wire with a colored stripe and a colored cqt5 with a white stripe. However, the rules for cables with so few pairs are lax. Most often you will find the pairs consisting of a white wire with a colored stripe and a solid colored wire.

Sometimes the white wire may not even have a stripe it may have dots or just be associated by the color of the wire it's twisted withand sometimes it's not even white being gray or transparent. Some cable has all solid colors in untwisted pairs avoid completely as it is not CAT-5 rated. The table at right shows the order of the wire pairs.

The color standard covers cables with more than four pairs, but that is out of the scope of this discussion. Phone and network connections both use a "Registerd Jack" RJ type connector.

Phones use RJ connectors, networks use RJ connectors, which are a bit wider. The RJ type connectors are often called "modular connectors". Traditionaly when working with modular connectors, the hook will be underneath and the contacts pins will be on top. The diagrams below and the wall jacks follow this standard. Typical phones use 4 or 6 pin RJ connectors see Figure 1 at left.

Most phone cables have four wires, but most phones only use the middle two. Click on the picture to switch between CAT-5 and regular phone cable. Although they look physically straight in Figure 1, phone cables are ars " crossed ". Wires in RJ connectors do not follow a linear order left-to-rightinstead they follow a centric order, working from the center pins out see Figure 1. To make connections compatable with both ends of a logically " crossed " cable, it is necessary for every pair in the cable to have each wire equidistant from the center of the connector either that or every cable would have to have all 6 wires, a big waste.

Click on the picture to switch between the standards. Although they look physically crossed in Figure 2, network and ISDN cables are logically " straight ". Wires in RJ connectors have a mix of centric and linear ordering. The two middle pairs are centric ordered, the two outer pairs are in linear order. See Figure usex. Note that for the RJ and both RJ standards, the wires will alternate between white-striped and solid-colored.

Cah5 crimping on a modular connector, you should never get two white-striped usfd next to each other, nor should you get two solid-colored wires next to each other. This is important to remember when pinning pair 1 blue whose second wire solid-color is pinned before it's first white-striped. As it happens, these are the only wires that are used jn network cables.

Network protocol does not use pair 1 blue or pair 4 brown. You can click on the pictures to hide and show the unused pairs. ISDN cables use all four pairs. Both standards are completely compatible with all network and ISDN equipment and each other.

You can plug a A cable into a B jack. The only difference is the insulation color of the wire ar signals will travel, and electrons don't care about that. As long uwed both ends of a cable are wired to the same standard, the cable will work. We recommend the A standard because it is similar to the wiring for an RJ connector. Notice that the 4 middle wires in the A figure to the right are the same as the 4 wires in the RJ figure above. In the B figure below, only the middle 2 wires match the middle 2 wires in the RJ figure.

We will then identify each cable by plugging in a wire sued to each cable. If both cable types are wired to the same standard, testing will be easier with less re-crimping.

Another benefit is a cable can later be changed from phone to network or vice versa or to both with less confusion and work in keeping the colors correct. The drawback is most off-the-shelf equipment is wired to the B standard. The Leviton jacks have a pin designation for both the A and B standards. However, the CAT-5 patch panel that we will use to distribute the phone service is usually marked for one standard or the other. A simple solution is to use paint pens and recolor the posts on the patch panel.

Finding a A patch panel will be more difficult, but having a patch panel that is marked in the same standard that you are wiring is worth the hassle. Phone cables are logically "crossed". A pin ade one end of a crossed cable does not lead to the same pin on the how to do a reverse parallel park in australia end. Instead, it leads to it's mirror opposite on the other end. When you hold the two ends of a phone cable in the same direction, one is wired in the reverse sequence of the other see Figure 1 above.

This is not the same as a " cross-over " cable for direct computer-to-computer connections as discussed below. Figure 1 above and the table on the right show where a pin on one end of a crossed cable leads to on the other end. The same concept also applies to phone cables with only 4 or 2 wires.

Note that the concept only applies to male-male cords and female-female couplings phone cables. For male-female cables splitters and extensions the cable is not crossed but is logically 'straight' as described below. Network and ISDN cables are logically "straight". A pin on one end of a straight cable always leads to the same pin on the other end. When you hold the two ends of a network cable in the same direction, both are how to 7 segment display in the same sequence see Figure 2 above.

Figure 2 above and the table on the left show where a pin on one end of a straight cable leads to on the other end. Network and ISDN cables are logically straight whether they have same-gender or opposite-gender ends.

To further add to the confusion, a logically crossed cable can physically lay flat looking very straight when put on a table with the hook underneath at both ends see Figure 1 above.

…And What’s a Cat6 Cable?

Nov 12,  · there are 8 wires in a cat5 cable, but for 10baseT and baseTX, you only need pins 1,2,3,6 and the rest aren't needed so he can use the other 4 wires if he wants for phones if . Mar 15,  · The primary use of Cat 5 cables lies in structured cabling for computer networks like Ethernet over twisted pair. This particular cable standard provides performance ranging up to a MHz and works for both High-Speed Ethernet (two wire pair) and Gigabit Ethernet (four wire pairs). Additionally, the blue wires alone can be used on recrimped Cat5e cables for telephony, changing the connector from 8P8C to RJ Using Base-T or lower frees up wires for other uses. In the af Power over Ethernet standard, wires 4 and 5 are ground wires, an.

Although wireless is simpler for a lot of people, due to multimedia sharing, bandwidth on my home network and my slight paranoia about wireless security, I really wanted to use a hard wired solution for home networking. Having a wired network allows me to have a private, high speed, network at home for Internet access, file sharing, media streaming, online gaming console or PC , IP security cameras, or any other use of standard ethernet type wiring.

Lets get to it with considerations and planning! There are certain design considerations that need to be addressed based on your needs. I'll discuss this before materials because these questions will affect quantities, tools and materials needed. I also have a TV alcove where my cable TV is so that seemed like a good location to wire as well for things like video game consoles. I have cable TV in each of these locations so it seemed logical to treat the network the same way.

How many ports do I want in each location? Since the wall plates come in 1, 2, 4, and 6 jack configurations for single gang , I just went with 4. Why run one cable when its nearly as easy to run 4, right? Rather than vary the number, I just ran 4 drops to each location to provide maximum flexibility with out the need for local in-room switches. What is a good location for distribution? My cable TV already comes into this room and gets split to each room.

It is important to note that my internet comes into the house over the cable here too so if I move my cable modem here, it will be able to supply internet access to the entire network. Another thing to consider is the amount of space needed to mount a shelf to hold the network equipment. What path should the cables take? For me, my condo is on the 2nd top floor and have access to my attic.

My cable TV is distributed through the attic so it seemed like a good solution to run my home network through there as well. For single floor homes with a basement, the basement may be the best path. For multi-story homes you may have to be creative.

Outside may be an option or through an old laundry chute. I will not address the specifics of all the possibilities, just my own circumstances. The other consideration with cable path is cable length. This should provide plenty of flexibility for most home applications but it is good to be aware of this limit. What network speed do I need?

You can probably pick up one really cheap at a used computer store or maybe even free. You might consider mbps if you are planning on sharing multimedia over your network. Gigabit is probably overkill in most situations but if you must have the fastest, go with it. You will also likely want to use Cat-6 in this case as well. Beware, gigabit switches more than 8 ports climb in price very quickly. Next up, tools and materials!

Your tools and materials can vary a lot on your needs and what you already may have. Since I knew the path my cable TV took and they were in all the same locations that I wanted my ethernet jacks, I just located my cable TV jacks to start.

Using the stud finder I was able to tell which side of the cable jack the stud was located on. Studs are located 16" apart in almost all homes and I knew I wanted my ethernet to go in the same wall cavity as the cable TV. Now that you've decided where to mount the box, you need to draw the lines on the wall to fit the new box and cut the hold with the pointed hand saw. The pointed saw should be able to push through the dry wall pretty easily without the need to drill starter holes.

Once you have the hole cut in the wall, you can put the single gang box into the hole and screw the clamps with hold it in place by clamping to the back of the dry wall. Repeat this for each location that you want to run to.

For now we'll leave the wall plates off. At this time you'll also want to cut a hole in the wall in the distribution room. Here you want to cut a hole that the plastic grommet will fit into. Now we can run cables! There are a number of ways to do this, you can estimate, measure from floor plans, run one, etc. I used the run one method. To find the lengths required for each run I ran one cable to each room from the distribution room, pulled it out, and made 3 more like it.

After that, you can run all 4 together. You'll also want to label both ends of each cable with a sharpie. This way you can label the ports on both ends. Before you can do this however you need to drill through the wall top plates so that you can drop the cables into the walls where you have cut your holes.

Finding the right place to drill in the top plate to make sure you get in the right 16" gap between studs can be tricky. This is another reason I decided to follow the coax cables for cable TV. I traced down the cable TV through that attic and then drilled new holes in the top plate right next to the cable TV holes.

You'll want a powerful drill and either a paddle bit or a hole saw for this. The hole saw is easier but the paddle bit is cheaper. You can also opt to drill multiple small holes and use one for each cable although this makes running them a but harder since you can't tape the bundle together.

Once you have the top holes drilled you can string out some cable to measure how much for each run and then cut 3 more equal lengths per run and then re-run the cables. Be sure to make them long enough that you have some extra from stripping and crimping accidents.

Its always easy to tuck extra length into the wall. Next, making connections. Now the we've got the cables run we can punch down the the cables to the patch panel and the to jacks!

I noted in the materials that a patch panel was optional. I feel that for permanent installation it is much more professional to mount a patch panel. This is pretty easy. Most patch panels and jacks have diagrams with wire color diagrams for the common TA and TB wiring standards. To be honest I don't know if either would work. Make sure you use the same on both ends. You can use the punch down tool or a small screw driver to punch the individual wires. Once you have all the cables connected you can mount the patch panel to the wall and click the jacks into their respective wall plates on the other ends.

You can also screw the wall plates into the gang boxes. Now we can check that things work! Now before you start connecting most of the network components you want to test all the connections and make sure things are working.

This can be done a number of ways. You're on your own. However the method I used was a little different. I plugged a short patch cable from my patch panel to each port on my switch and turned it on. The next step is to take another patch cable and a laptop and plug it into each port in each room. Check the switch after each port and verify the "link" indicator is on. Being able to establish a link tests the physical layer i.

No IP addressing or anything needed for testing. This is also a good time to make sure your labeling matches on both ends. For example you can make sure that "Master Bedroom Port 2" on your patch panel actually goes to the second port in the master bedroom. To the internet, and beyond!

Now that we've got this fancy network, we want to connect it to the internet right? First the cable modem setup. Since I moved my cable modem from my second bedroom office to the distribution room I needed to change the way my cable was split.

Rather than the main cable into the house being split 3 ways I split things a little differently. I split the incoming cable with a 3-way splitter first. I connected the splitters using a male-male barrel connector.

Now that the cable modem is in the right place we can continue with our network setup. Depending on your internet provider some of this setup may vary. I'm going to discuss the specifics of my environment only. I'll provide tips for others when possible. From the "Trusted" port, I connected to the first switch port on my switch. If your switch has one, plug into the port labeled "Uplink" instead. Depending on the switch or cable modem and or router, you may need or already have crossover cables for these connections.

In addition my entire network is protected from outside access by the firewall. Although it is not integral to this instructable, I also plugged a wireless access point into my switch so that I can have wireless access as well. Since my wireless is both encrypted and has MAC filtering I feel comfortable with it on the "trusted" side of my firewall.
