Spot on, Mr. Rivera

[@PE4Doers]

Thanks for the nice comment

[@Practical-IT]

In all my years working with Ethernet and PoE, I'd never heard of the Type 1/2 designations. I'd always seen and heard it discussed as 802.3 at or af.
So, good job on the video. I'm always happy when I learn something new from another TH-camr.

[@PE4Doers]

Thanks Jeremy. Like USB technology, I've received a couple of comments from people trying to understand PoE. Now that it's posted however, I wonder if I went a bit too far talking about the circuitry. Maybe I should have spent more time chatting about the gauge of the cabling, since that will allow for more distance.

[@mrd4233]

Your videos are top Quality on IT sector!

[@PE4Doers]

Thank you Sir, I truly appreciate you saying that. and for the comment in general.

[@frankking6308]

Pure gold.

[@PE4Doers]

Thanks you so much for commenting that 🙂

[@HarmonicPolyphonic]

Your voice and teaching style is so calming and informative!

[@PE4Doers]

Thanks you so much Emm

[@danmekeel7758]

You are a Very Good Teacher, explained in layman's terms, folks in the field.

[@PE4Doers]

Thank you. I do appreciate hearing back from people who have found one of my videos useful

[@ruralcapers9253]

A wonderful video that has really set me straight in regard to POE. It was very well done and from a technical perspective very well explained. I now have a wonderful insight into how POE works and will be applying this solution to the current problem I have Merci Sir....

[@PE4Doers]

What current problem are you having?

[@QuikTechSolutions]

Outstanding explanation, well delivered! 👍

[@PE4Doers]

Thanks Tony, much appreciated.

[@KathrinHausermann]

Brilliant Video :)) I did not know Cisco invented the POE Standard :)) in your videos I can always be assured I learn something new I did not know before:)) Thank you very much for all the effort you put in your videos :))

[@PE4Doers]

You are very welcome Kathrin. As always, thank you for watching 🙂

[@bornlibra23]

Hats off sir.

[@PE4Doers]

Thanks you very much 🙂

In an effort to cut costs and increase profits, some sellers offer Cat 5 and Cat 6 cable made with CCA (copper clad aluminum) wire, small diameter wires such as AWG 26, or a combination of both. This has the potential to significantly reduce the output of the switch/injector. With longer runs, especially when using POE+ or POE++ it would probably be best to use a pure copper AWG 23 Cat 6 cable.

[@PE4Doers]

I fully agree - copper. In addition to the great points you make, that clad'ed wire also tends to loosen up in the connectors over time at a significantly faster past than pure copper.

Hi, if power and data together with 12 36 pair. Which one is for data?

[@PE4Doers]

What do you mean by 12 36? In POE, the power and the data share the same wires. I describe the details of that at 15:27 in the video. The power is a constant level, however the data is variable square wave.
