plug cat 6

Hello everyone.
I bought some plug cat 6 FTP and I saw that they are two different types.
Some have eight wires arranged in a single row, others in two rows of 4 wires.
I searched on the web but there are no answers. Only one site is about this difference and distinguishes the first in cat 5e and the second in cat 6.
But I'm not sure of this response.
What are those that meet the requirements of Cat 6?
Can you help me?

Hi There,

This is a good question. The staggered teeth within the connector are designed this way because the Cat6 gauge is bigger than Cat5e. This is also because of the insulation type used. I have personally made Cat6 cables here and had to use the right connector because they simply wouldn't fit into an ordinary Cat5e connector.

The wiring order is exactly the same. In some cases you can use the plastic piece to feed the conductors into before you slide this into the connector but this is generally for Cat6 solid core strands or conductors that are smaller (perhaps with a thinner insulation).

I hope this helps.

Best Regards

Hi There,
Thanks for your reply. This is my new question: there is a certification that sets the standard of the two types of plug (cat 6 = 2 rows of four-wire, cat 5e wires in a single row = 8) or the use is the same (... and depends on the thickness of the wires)? may also be different for different electrical certification (so I've been told by the sales engineer of the product)?
I doubt this because the cat 6 patch cables (purchased by lindy) are the first type ...
Thank you all for the answers.
Best Regards

Hi There,

OK Yes, the resistance between the Ca5e and Cat6 conductors must be different because of the difference between bandwidth support, hence the thicker copper conductor.

Here is some more information:

Cat5e and Cat6 Comparision

Category 6 Cabling System and Application

Why do I need all the bandwidth of category 6? As far as I know, there is no application today that requires 200 MHz of bandwidth.

Bandwidth precedes data rates just as highways come before traffic. Doubling the bandwidth is like adding twice the number of lanes on a highway. The trends of the past and the predictions for the future indicate that data rates have been doubling every 18 months. Current applications running at 1 Gb/s are really pushing the limits of category 5e cabling. As streaming media applications such as video and multi-media become commonplace, the demands for faster data rates will increase and spawn new applications that will benefit from the higher bandwidth offered by category 6. This is exactly what happened in the early 90’s when the higher bandwidth of category 5 cabling compared to category 3 caused most LAN applications to choose the better media to allow simpler, cost effective, higher speed LAN applications, such as 100BASE-TX. Note: Bandwidth is defined as the highest frequency up to which positive power sum ACR (Attenuation to Crosstalk Ratio) is greater than zero.

What is the general difference between category 5e and category 6?

The general difference between category 5e and category 6 is in the transmission performance, and extension of the available bandwidth from 100 MHz for category 5e to 200 MHz for category 6. This includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). These improvements provide a higher signal-to-noise ratio, allowing higher reliability for current applications and higher data rates for future applications.

Will category 6 supersede category 5e?

Yes, analyst predictions and independent polls indicate that 80 to 90 percent of all new installations will be cabled with category 6. The fact that category 6 link and channel requirements are backward compatible to category 5e makes it very easy for customers to choose category 6 and supersede category 5e in their networks. Applications that worked over category 5e will work over category 6.

What does category 6 do for my current network vs. category 5e?

Because of its improved transmission performance and superior immunity from external noise, systems operating over category 6 cabling will have fewer errors vs. category 5e for current applications. This means fewer re-transmissions of lost or corrupted data packets under certain conditions, which translates into higher reliability for category 6 networks compared to category 5e networks.

When should I recommend or install category 6 vs. category 5e?

From a future proofing perspective, it is always better to install the best cabling available. This is because it is so difficult to replace cabling inside walls, in ducts under floors and other difficult places to access. The rationale is that cabling will last at least 10 years and will support at least four to five generations of equipment during that time. If future equipment running at much higher data rates requires better cabling, it will be very expensive to pull out category 5e cabling at a later time to install category 6 cabling. So why not do it for a premium of about 20 percent over category 5e on an installed basis?

What is the shortest link that the standard will allow?

There is no short length limit. The standard is intended to work for all lengths up to 100 meters. There is a guideline in ANSI/TIA/EIA-568-B.1 that says the consolidation point should be located at least 15 meters away from the telecommunications room to reduce the effect of connectors in close proximity. This recommendation is based upon worst-case performance calculations for short links with four mated connections in the channel.

Best Regards

OK! regarding the types of cables I had already seen the differences on the web.
I just wanted to know if there is or not a certification by the ANSI / TIA / EIA for the plug (example... 8 wires in 1 row = cat 5e, 4 +4 = cat 6) or if their use is made according to the thickness of the copper wires of the cable ..
I ask these questions because I bought the plug shielded cat 6 Lindy (code 62435) that are the first type (8 in 1), so if there a certification the plug was cat 5e and not cat6; then I bought the cat 6 patch cables Lindy that are the second type of plug (4 +4).
I therefore ask if there is a certification (and I should change the plug) or can I safely use the plug Lindy.
Thanks for your patience with me ...

Hi There,

The specification comes before the certification. Please see some details in the link. ... 020402.pdf

sorry if I insist, but maybe I have not explained well. I just wanted to know only if there is or not a certification ANSI / TIA / EIA that distinguishes the two types of plug in cat 5e and cat 6 on how to arrange the wires inside the plug (8 in 1 = 4 +4 = cat5e and cat6) , or if there is no difference in their use (they are selected according to the thickness of the copper wire).
Thanks for your great patience with me ...

Hi There,

I don't think so, it still falls under the Cat5e or Category 5 connection specification as far as I can see on the internet. Cable manufacturers will follow the electrical specifications for Cat6 cables that have been specified by ANSI/TIA, but things like the insulation thickness and construction of the cable, mainly the outer will vary. I have personally made Cat6 cables using Belden cable which also fit into the standard Cat5e connectors well.
