Often, the Eternet MHz speed classification of Ethernet cable is an important selection box for many shoppers. What does this mean exactly to your network? Does the high speed of the MHZ cable it comes when it comes to the Ethernet cable and its category? Is this equivalent to the highest application speeds? The answer is not yes or no simple, as it is likely that you have been guess now. Let’s pump the brakes for a moment and start determining what some of these terms really mean. Then we will put this in a real situation so that everyone can understand it.

MHz or Megahertz definition

Megahertz is shortened because MHz Megaherz is measuring the speed of the clock for the speed of something that Megahertz can go, for the stranger, it is an electric frequency (note in the electrical part)

How do you imagine this? Think of MHz as the width of the water pipe. The wider the tube, the more water it can handle.

A specific category

Ethernet category (Referred to the name CAT) is the specific criterion that manufacturers use when creating an ethernet cable. It determines how the cable category should lead to a specific maximum distance. In the case of the United States, Ansi/tia Limte determines the standard of building material cables and strongly determines the electrical performance part of the standard-the most recent is ANSI/TIA 568-2.D. In the event of cable standards outside the United States of America, the standards are defined by ISO/IEC 11801. from time to time, ANSI/TIA and IEEE (responsible for IEEE 802 network standards) speaks and agree on what the actual actual category cable standard should be used for a specific data rate, which is called “application scope view”.

Specific domain display

10GBASE-T, 1000BASE-T, 100BASE-TX: Translate into 10 GB speed, 1 GB speed, 100 MB speed. For your information: 1000 MB equals 1 GB and 10,000 MB equals 10 GB. The application protocols are strictly defined, literally determined how quickly your network is on the operation, and this is called the application range width of the application. Application protocols determine these speeds that you will see “on the ground” of your network to work in the full frequency range you are looking for, you should support all components in the series the same as the application protocol or higher … including Ethernet cable. Sometimes, even the program you use can hinder you. Betcha does not know that! To get a deep diving on how this happens, check out Free white paper: 10 GB test on copper with a limited budget. There is a direct relationship between the application range of the application and the amount of money you need to spend to achieve this. 10GBASE-T Equipment is expensive, while 1 GB equipment is more than a commodity and a price this way.

Information can be found about the choice of ethernet cable as it applies to the application range width of the application in our blog, What does 10/100/1000 Base-t mean?. To see a more advanced discussion about what this translates to the speed of Ethernet MHz, see The need for speed.

Put everything together: How Eternet MHz affects the real performance

So far, we have identified what these terms mean, but they took their own not telling you how it might or ethernet MHz in terms of ethernet cable.

To support the highest app protocols such as 10 GB (10GBASE-T), the megaherz is the highest (Megaherz) whenever the MHz Ethernet cable increases The material construction of the Ethernet cable It plays an important role in this … Solid copper Ethernet conductors are better than the two -ways that are cut, especially copper aluminum (CCA), which is the minimum of the currently accepted copper scale is 24 AWG, while the maximum is 22 AWG connectors that are not the only standards to support the higher Megaherz. Below are factors: thickness of the outer cable jacket, plastic insulation thickness around copper conductors. Read our blog, Why are the wires twisted inside the ethernet cable? For more information. The ethernet cable should be properly balanced to support the required data transmission speeds. This is why the Eternet Copper Cable Cable is called “balanced twisted cable”.

Therefore, the physical construction is very important, and for this reason ANSI/TIA select the categories in ANSI/TIA 568 2.D. What are the lowest frequencies to achieve a specific frequency offer at a certain distance?

The relationship between the frequency (mHz speed), the display of the frequency range, and the distance

You will notice what ANSI/TIA recounts the maximum distance of the supported domain display. What many people do not know is that many cable categories can support much higher frequency range in significant shots. One of the great examples of the point, which was identified by Ansi/Tia, Cat6. Cat6 10gbase-T can support as long as the length is kept to less than or equal to 165 feet (under the ideal conditions, I). In addition, enthusiastic people will notice that there are faster speeds to apply the Cat5E and Cat6 (2.5gbase-T/5GBASE-T) However, the MHZ speed is not required to increase with high speeds. This is a matter of continuous discussion and will be discussed below.

Prefabble meals?

You can, and you have tested it, run 10GBASE-T via Cat5e cable up to very short distances like 20 feet without any errors or problems. At longer than lengths, you will have abundant beams.

This does not mean that Cat5e will pass the tests test on any length to the specifications of Cat6a. In fact, it will fail greatly. This also does not mean that you should exceed ANSI/TIA specifications at a distance. You should not. The criteria exist for some reason.

Supporting the highest Megahertz values ​​means more frequency range width, and therefore, higher Ethernet transmission speeds.

Pictures are equal to a thousand words.

PIP explosion as an example

What happens when you try to run 10gbase-T via Cat5e on 200 feet?

I just joke. The image above does not really mean that the cable explodes like the tube. What will happen is that your network will begin to drop the packages and try many mistakes.

Think about different categories such as tubes like this:

Examples of the ANSI TIA Class Gall Disorder

Each tube has a different view, which equals the amount of data it can carry. That is why Cat6a can carry 10 GB, and it is actually determined to do this without errors.

The big question that recently answered: Is it more important to MHz?

Yes. The MHz ethernet cable is defined by the standard to allow the installation of the ethernet cable with an emphasis that the speed of a specific frequency range can be achieved at a certain distance.

Does the minimum MHz exceed speeds?

You may have noticed a trend as many manufacturers (listed in Truceted) in the ethernet cable classification to display the MHz domain MHz are much higher than what is required according to the standards. For example, Truecable 350 MHz sells Cat5e, but the minimum required per standpoint is 100 MHz. What gives? Enter NBASE-T! You can read more about NBASE-T in Just what is NBASE-T?

Network technology has advanced slightly, and there are continuous discussions surrounding the requirements of the minimum MHz to support 2.5gbase-T and 5GBASE-T. Initially, ANSI/TIA engineers selected for CAT5E to support 2.5gbase-T and 312 MHz to support 5GBASE-T in the draft documents. In contrast to the official 100 MHz for Cat5e and 250MHz for Cat6. In mysterious circumstances, MHZ requirements were dropped from the draft documents (without interpretation) but the new NBASE-T application speeds were submitted anyway.

As it turns out, these new application speeds seem to really require higher MHZ speeds in some cases and not clear what specific conditions make this necessary. In order to cover their bases, manufacturers have begun to produce ethernet that could deal with the highest official minimum just to make sure. But this creates another problem, especially with the Ethernet Cat6 U/UTP cable paid to 5 GB/s: excessive cable to speak on the correction panel.

Reports from the field fasteners indicated the use of an unprotected Ethernet cable (U/UTP) with standard CAT6 (direct punch via or less tools directly) Anext or foreign mutual modern In the correction board while paying 5GBASE-T. Previously, this phenomenon was only seen with unprotected cat6a paid to 500 MHz (10G speeds) in the correction panel. Looking at the debate about whether 312 MHz is the real frequency range required for 5GBASE-T, this begins to make it more logical and is more evidence that ANSI/TIA is at least 250 MHz insufficient. Anext begins to become a problem near 350 MHz, which is not far from 312 MHz. coincidence? Most likely no.

There are two ways to alleviate this:

There you have. Several people have tried over time to explain what the MHz Eternet cable for the DIY medium person means, and with varying degrees of success. We hope you have a much better understanding now.

Happy networks!
