Modern technology has given rise to various electrical demands. The large variety of product offerings for our different digital needs has led to the distribution of so many items that is is often to difficult one from the other.
The RJ45 and CAT5 are two terms commonly found in cable technology and often thought of to be synonymous. In actuality, the two are different non-competing items with different functions. It eventually evolved in function, presently used for wired computer networking. Regarding OP's link to a no-name plug, I think it's mostly marketing. While there can and should be differences in how plugs are designed, in the no-name space I don't think you'll find a consistent set of differences between no-name Cat5 and Cat6 plugs.
The same brand uses a "smart connector" for the 8P8C plugs as well. But this is a name-brand structured cabling system. Cabling systems will typically be installed by certified installators, and be validated end-to-end after installation by measuring that they meet or exceed an agreed level of performance.
Sorry, I know this is resurecting an old thread, but I felt like I needed to put my 2 cents in Among those things are the RJ45 connectors clear plastic male plugs as well as the female jacks. The connectors are used for backwards compatibility. With the use of RJ45 connectors we are then forced to use the familiar 4-pair signal wire. Externally everything looks the same. It has to in order to be physically compatible and give you that satisfying "click" when you plug things in.
Internally, much tighter specs need to be adhered to ensure conformity to each of the standards. One of the CAT6 specs requires separation distance of the twisted pairs to prevent cross talk. The most common way by manufacturers to achieve this distance is a plastic insert that runs the entire length of the cable. It's like having 4 workers separated in cubicles each pair of singal cables being a worker and allowing said workers to carry more private phone converstation than if the cubicle walls didn't exist.
Now what happens when you open that cable up to field terminate it into an RJ45 male connector? They were right next to each other I always thought how magical it was that I could simply lign up and pinch the wires between my thumb and index fingers and shove them into the connector and be able to rely on small guides to keep the cables in check. Very seldom, I would look into the connector and see that my colour lign up had gotten "guided" into the wrong channel.
Other times I've done troubleshooting on a network connection for a computer and it's turned out to be a simple patch cable problem. Replacing the cable fixed it. Inspecting the cable afterward showed that it was miswired. So, the old connectors allowed cock ups like this and as well, allow the cables to move horizontally to come close enough to each other again to create this "cross talk" phenomenon. If the singal wires were put into the connector and checked before termination, miswiring could be prevent.
Cross talk can occur even after termination though. That cubicle shaped separator that added so much cost into the length of the CAT6 cable would then been negated if used with a CAT5e male connector.
Manufacturers then added a tiny, rediculously annoying piece to the male plugs to fix this and be in conformance to CAT6 separation requirements. The additional piece is a template which forces you to first put all the coloured wires into it, ensuring separation of the signal wires and prevention or horizontal and vertical movement after termination.
Why is cross talk such a problem? Cross talk is really just "leakage". The same ability of ours to send a tone down a wire and listen to it through induction is the effect of one wire leaking it's signal into another wire adjacent to it.
Receiving equipment would get confused and sometimes ask for retransmission of the data packets being sent. This means lost bandwidth as the available bandwidth is being used to transmit the same data twice. To get that 10Gb, you can't have signals being retransmitted to often.
You now need thicker copper cable to create less resistance of electrical signals. For that CAT6 cable from most manufacturers has a slightly thicker gauge as opposed to more pure copper. Then there are certifiers as well I just want to add one thing that nobody else has mentioned yet. There are also different plugs for use with either stranded or solid wires. Although you may get away with using the wrong one it is preferable to ensure the correct one is used, as it will give you more reliable cables.
The differences between these two types of plugs is in how the connector pin pierces the insulation and contacts the wire when crimped. For solid wire, which is cheaper adn normally used for fixed wiring, the insulation is broken on each side and the wire is wedged by side contacts. For stranded wire, which is preferred for patch leads, there is an additional middle prong which is designed to pierce the insulation and go between the strands, as well as the two side contacts.
Physically they may look the same but if you want an actual Cat 6 cable it's very unlikely you are making it yourself. The tolerances for Cat 5e, in terms of amount of un twisted cable you could have in the plug, were tight already. Cat 6 and you don't really stand a chance. However it is worth noting that unless you are planning on pushing 10G ethernet over them up to 40M then you might as well use a Cat 5e cable. Additionally, ensure that the wires when cut are of equal length and pushed all the way up into the plug so the copper is flush at the top.
They look nice, and the companies that make patch cables can sell them for more money. Also, when you pull a cable back through a nest of other wires the boot keeps the locking tab on the plug from getting snagged and broken off. That probably isn't a big concern for most home networks! Do boots keep dust out? Possibly, but a jack with a plug in it shouldn't be getting dust in there anyway It has no relation to the category of the cable e.
These terms refer to the material used for the outer jacket of the cable to meet certain safety requirements. Plenum rated cable is required by some fire codes if you run network cables in locations where the an air handling system moves air -- such as above suspended ceilings plenum areas. Plenum cables are often used in commercial spaces and are designed to withstand higher temperatures than ordinary PVC jacket, burns less readily than PVC, and emits less toxic fumes when burned.
Thus, if a fire does occur in an office, there is less chance of toxic fumes to circulate throughout the building. If an office building uses air ducts, plenum cables are may not required - check with your building or local city code on what's required.
Riser cable is a type of PVC cable and are designed for use in walls or in vertical cable runs between floors in non-plenum areas. Typically, they are install inside cable conduits and the jacket material is designed to minimize fire from spreading from one floor to another.
However, the fire rating of riser cables is not as strict as plenum and thus should not be as a plenum substitute. PVC Polyvinyl Chloride cable is what you you commonly buy for most of your home or office space networking cabling. These are often used in server rooms and network runs throughout office rooms. However, these are not fire-prone and thus should not be used in plenum spaces. For most homeowners, plenum rated cable is not necessary and they typically costs two to three times more than PVC.
There is no electrical or performance difference between the two and either will perform equally well. Each network cable contains four pairs of color-coded wires, each pair twisted at a regular rate.
Better grades of cable deliberately apply different amounts of twist to each pair. The twists provide a consistent impedance along the length of the cable, reduce the cross-talk electromagnetic interference between pairs and tend to make induced noise cancel out. To preserve these qualities, it is important to maintain the twist when installing connectors, right up to the point of termination.
You shouldn't untwist more than about a half an inch of wire. And when you install the cable, take care not to pull it tightly or make sharp bends, as those will disrupt the pairs' integrity. The difference between these two is STP has a foil shield that covers the four pairs of wires.
This adds an extra layer of protection against cross-talk electromagnetic interference between pairs. Between the two, UTP is the most commonly used - both for home and business settings - and it's cheaper. STP is typically used in industrial facilities where heavy equipment and other electrical machinery are found that can introduce interference or when using high-performance cables such as Cat7.
For most homes and small offices, there is very little to gain in using the more expensive STP. Both are "punchdown" blocks used to interconnect voice and data systems in an orderly way. Type 66 blocks have been around longer and were developed for the phone company; they make it easy to connect multiple phone taps to a given line, and with the use of bridging clips provide an easy way to disconnect inside wiring from a circuit for troubleshooting.
Older 66 blocks are not suitable for category 5 wiring, although several manufacturers have come out with revised 66 blocks that will work. Most Category 5 jacks also use type terminals for connecting to the wire. Both kinds of impact tools both connect and trim the wire to the correct length. For a couple of bucks you can get a plastic tool for blocks that might get you by for a few connections, but it won't trim the wire.
Personally, I would stick with an impact tool. Coax cable using the RG connector for networking Thin Ethernet or 10Base2 was common place in the s and the early part of s.
