UniFi: Beginner’s Guide to Network Cabling | Part 1 - Cable Types & Termination

In this episode we cover the key differences between ethernet cable types, where they are appropriate to install, and how to terminate using a RJ45 connector. Sean Croghan, a network engineer and installation professional with 20 years of experience, explains everything you need to know so you can run your own cables for your next UniFi deployment.

Stay tuned for more UniFi Beginner’s Guide to Network Cabling episodes to help you run your own cables in homes and small to medium sized businesses using UniFi Design Center.

Looking forward to better quality content from this channel! This video is a great start to a great series.

[Dextermorga]

Finally, somebody mentioned rj45 for stranded and solid wire connectors 👍

[danielgreen]

Great educational content. People take for granted basic knowledge and rarely share the basics. Thank you.

[ThiagoNunesRS]

The videos is getting better. Very good!

[geoffswan]

Informative video. Should probably also have mentioned that pin 1 of the RJ45 is the leftmost pin when the connector is held vertically with the pins facing you, and that this is the orange/white wire for 568B cabling.

I can't wait for the rest of the series! Thank you ubiquity these episodes will be VERY helpful. Thank you!

[crystalyzzed]

Ditch all other paid channels and focus on this type of content! This is great. Been installing Ubiquiti products for 6 years and this type of content is great for newcomers to get familiarized.
Other consumer, anecdotal oriented content is garbage IMO.

[mpxz]

These are fantastic videos.
You sir, know what you are doing!
This is the best content that Unifi has ever released.
Perfect

[pamelawebber]

I learned with this type of crimp and rj45, but I have found the pass-through clips/crimper much easier to use. Great instructional vid though, good job!

[empy]

Awesome video, can't wait for the rest of this series.

[RelativisticVelocity]

I always thought the floss was there for pull strength to relieve stress on the copper when pulling long distances, never considered using it to to remove the jacket.

[VladimirSaneeh]

Super useful! Thanks for making this video.

[Bench]

Awesome Video!! Can't wait for more!

[ryoohk]

Another tip.
To help untwist the wires you can use part of the jacket you strip off and push it between the pairs so that one wire goes in to the jacket and the other stays on the outside you can just twist the jacket in your fingers and it will slide down the pair and help untwist them easier.

[michaelzera]

Very well done. Super informative. Great job!

6:53 The (solid/stranded) lables for the RJ45 crimp types graphics are reversed. Stranded core is used with the top blade type, while solid is used with the lower fork type.
I’ve seen professional installers incorrectly use the wrong type! Which will later cause connection issues due to bad connections.

[Deraco]

Nice video, however, Sean never specifically mentioned the orientation of the RJ45 connector (He did it on video but never went though why). This is NOT required for most, due to Auto-MDIX, but this is an important thing to know

The pins are suppose to up face when putting the wires in. Pin 1 is first from the left when pins are facing up. For T-568-B, that's Orange-White. I noticed two of the graphics, the pins were wrong the first time, then they were right the second time.

[Gaijin]

Keep them contents coming :)
oh and dont forget to restock them g3 flex

[hitmani]

I just been doing low voltage for only 15 years. But I was told by people with more experience that always try to use the dental floss (ripcord). But maybe it's more important for terminating to a jack or patch panel where the jacket is not supported and camera ends.

This is awesome! it would be great if you could add thumbnails of tutorials inside the controller, for different tasks. This would help a lot, and attract even more customers to switch to Ubiquiti. Also, inviting customers to tell their stories, and how it changed/improved their business would be also a good idea IMO. For example, I loved the live chat feature, the option where the tech support did certain tasks (faster than explaining them), and by watching how it was done, I didn't have to go back and ask for support ever again (for that certain feature setup).
