Are CAT 5 sockets compatible with CAT 7 cable?


SOLUTION: I have found RJ45 connectors that are compatible with Cat7 and can also be used with the standard cat 5/6 crimpers. These do not provide speeds higher than would be expected of Cat 6a, and are a bit more expensive, but at least I can use the cable without paying 30€ a time for TERA connectors or having to bodge the whole thing by stripping the internal wires. See the link below.


I have a lot of Cat 7 shielded cable and I want to make sure I am using the most advantageous connectors to get the most out of the cable since I now have a top of the line D-Link switch that supports Cat 7. Literally ALL of the connectors I have viewed online say they are for cat 6 or earlier. I understand that I will need a specific cat 7 crimper for the cable itself because it is slightly thicker than...

Cat5 vs Cat5e vs Cat6 vs Cat7 Cables

Cat5 and Cat5e and Cat6 and Cat7 are different standards for cables. If you are wondering if these names of some species of cats, you are wrong. These are types of twisted copper cables that are used to transmit data through network and also used in home theater applications. Category 5 (Cat5), Category 5e, and category 6 are the names given to these cables depending upon their performance level. Telecommunication Industry Association (TIA) and Electronic Industries Association (EIA) are organizations that set guidelines for the production of these cables which help manufacturers to classify these cables.

Cat5 has almost become a standard for connecting Ethernet devices world over. It is inexpensive and very effective. It is also available readily making it the most commonly used cable for connecting Ethernet devices. It is available in two types, the Unshielded Twisted Pair (UTP), and the Screened Twisted Pair...

Cable Types and Speeds

Selecting the appropriate category

When selecting the appropriate category of cable to support your network, note that there are different grades within each category. A higher grade cable with the proper installation will allow for a higher margin of error, ensuring top performance today and an extra buffer to support future technology.

Properly selecting Cat5, Cat5e, Cat6, Cat6A, Cat7 or Cat7A solutions will optimally support current and future network speed requirements.


Cat5 supports speeds up to 100Mb/s (100 MHz)


Cat5e supports speeds up to a Gigabit Ethernet (1,000Mb/s) (100 MHz)


Cat6 supports speeds up to 10 Gigabit Ethernet and can be achieved with distance of 37-55 meters or less depending on the grade of the cable and quality of installation. (1,000Mb/s) (250 MHz)


Cat6A supports speeds up to 10 Gigabit Ethernet with distance up to 100 meters...

How to Identify

Most Ethernet cables have the cabling category printed on the cable, with the print typically displaying how much bandwidth the cable can transmit. Telling cable categories apart by coloring or thickness can be difficult and unreliable. To be certain of which cable category you are buying, check the printed information.


Neither a CAT5 cable nor a CAT5e cable will make your internet connection faster. Rather, these cables are used to send and receive data at the speeds your internet is capable of (as per your internet provider) or from one computer to another in a network, in which case hardware can affect speeds.

CAT5 cables will work for network connections that are under 100Mbps, while a CAT5e cable can work up to 1000Mbps, a gigabit. CAT5 cables are more prone to interference issues, meaning they can struggle to transmit data even up to 100Mbps. Therefore, for a faster, smoother experience, you should use or upgrade to a CAT5e...

Remember that in a structured cabling environment (basically anything "Category" rated) ... the entire span takes the rating of the lowest rated component. So if you are using Cat6a cable with Cat5 jacks (good luck with that), the system is rated at "Cat5" level.

If you have a contractor install structured cabling for you, and he uses cheap, unrated jacks, panels, or connectors ... then (until they do a cert scan to prove otherwise) you will have bought an unrated system.

IN A COMMERCIAL INSTALLATION it is also important, for max performance and optimization, to use components from the same manufacturer. The reason is that each component is engineered based on the cable "as produced" specs; it's never perfect, not for any manufacturer, so manufacturers tend to compensate for the cable's deficiencies with the mating components, to produce a system that is balanced to the best degree possible. In some cabling systems, they will also provide a performance and compliance...

What is a Cat ’X’ Cable?

Quite simply, a Cat cable, also known as an Ethernet cable, is a cable that you use to wire a computer network. There are four different types of cable and each of them has its own specifications.

Quick Cable Type Comparison

The primary differences in these cables are found in the speed of the cable, how the cable handles crosstalk and also the bandwidth of the cable.

Ultimately whether you choose a Cat5, Cat5e, Cat6 or a Cat6a (or even Cat7) cable will come down to things such as your specific network requirements and your budget.

Difference Between Cat5, Cat5e, Cat6 & Cat6a Cables

Before we look at the differences in these cables it is probably a good idea to look at what they have in common.

As these cables all perform the same job, they all have the same style RJ-45 jacks and plugs. Furthermore they are all limited to a cable length of 100 metres.

These similarities mean that you can use these cables...

Cat5 Cable (SCTP)
(Screened Twisted Pair)

Same as cat5 patch cables described above, except that the twisted pairs are given additional protection from unwanted interference by an overall shield. There is some controversy concerning which is the better system (UTP or SCTP). Cat5 SCTP Ethernet cables and patch cords require all components to maintain the shield, and are used almost exclusively in European countries.

Cat5e, RJ45 jack
(Work Area Outlet)

An 8 conductor, compact, modular, female jack that is used to terminate cat5e patch cables at the user (or other) location. The jack is specifically engineered to maintain the performance of cat5E cabling.

Cat5e Patch Panel

A Cat5e Patch Panel is basically just a series of many cat5e jacks, condensed onto a single panel. Common panel configurations are 12, 24, 48, and...

CAT6 & CAT6a Strict Specifications With More Stringent Crosstalk and System Noise Features.

Category 6 cable, commonly referred to as Cat-6, is a cable standard for Gigabit Ethernet and other network protocols that is backward compatible with the Category 5/5e and Category 3 cable standards. Cat-6 features more stringent specifications for crosstalk and system noise. The cable standard provides performance of up to 250 MHz and is suitable for 10BASE-T / 100BASE-TX and 1000BASE-T / 1000BASE-TX (Gigabit Ethernet).

The cable contains four twisted copper wire pairs. This is the same as CAT5 and CAT5e copper cable...

Until you update to digital which is polarity sensitive in most cases.

Manufactures are making Data equipment IDIOT proof so that all that is needed is to run a cable and punch the "wires" down in the slots at both ends with out making sure it is right.

The ports will align themselves to the right pin outs regardless of the (fancy term) Wiremap.

Wiremap is a method to see what wire is to what pin.

Orange pair
Green pair
Data pins

Blue pair
Brown pair
Future use and or grounding for EMI interference.

Structured Cable comes to mind. The cable in a whole provides the stability and the green and orange are twisted more then the blue and brown pairs are. Cat6 has even more done with it. I will not go into a whole explanation of what mathematical science is used to create the cables twisting just know there is.

This basically has to do with magnetism. These pairs are twisted together in counter twisting rotations. If...

>> Telephone Plugs and Sockets for Australia


There are currently three different types of line termination connectors used in Australia for telephone and data use.


600 Series - Australian Style

This series is what is commonly called the "old Australian type" and has been installed in Australia, primarily by Telstra, for approximately 30 years. There is a huge installed base of this type of connector.

RJ12 series - US modular
This type of connector has been installed in Australia for a period of approximately 5 years, originally developed in the USA by Bell Labs (the same Bell that invented the telephone) by engineers Charles Krumreich and Edwin Hardesty, it has now become the most widely used telephone connector in the world. You will see it is used in the connection port for most telephones, faxes etc.

This connector is quite often misnamed, however in Australia it is commonly...

I really hate Wi-Fi, and you should too. If you own your own home or your landlord doesn’t mind a few holes in the wall, running gigabit Ethernet around the house is the best thing you can do for a faster computing experience. But what’s all this about Cat 6 or crossover cables? Here’s everything you need to know about Ethernet cabling.

We also have a free, downloadable guide to home networking with more information on the software side of a home network, such as printer and file sharing.

What’s wrong with Wi-Fi?

Wi-Fi will always be slower than a cabled connection.
