Twisted Pair Cables – STP vs. UTP Where Fiber cable would be used as a big backbone connection, a smaller, more localized connection is where Twisted Pair Cables. After completing this course you'll know and understand the purpose of twisted pair cabling design, how it transmits data, issues and disadvantages associated with using twisted pair cabling and the difference between shielded (STP) and unshielded (UTP).

Video Transcription
00:04
we talked about our
00:05
fiber cables that we use for our backbones. And again when we say our backbones we have We're talking about our big systems, such as we have our big Internet service provider and they have, ah, backbone fiber optic cable.
00:21
And we're actually using a fiber connection at the office building. And we would consider this connection here. Ah, backbone connection. Ah, more accurate representation of like a big backbone connection would be, say, connecting from an I S p in
00:38
the United States all the way to an I S P
00:42
in Europe, that would definitely be a very thick fiber backbone connection intercontinental on the ocean floor, protected against shark attacks and boat anchors. We'll just say that our
00:55
connection here between our Internet service provider in the United States to our office in the United States
01:00
is using a fiber optic connection, then inside of our office building
01:06
after we have to take that connection and we put it to our Cindy to Ara
01:11
are different. Switch boxes and our box, which interprets that fiber connection after that, we're going to be using our twisted pair connection now are twisted pair connection. We've talked a little bit about in our earlier videos, has twists in the line in order to protect against Am I Electromagnetic interference
01:30
are
01:30
twisted. Pair cables aren't like our fiber optic cables that transmit data with light beams are twisted pair cables transmit with electricity on because they transmit with electricity.
01:41
The signals are actually susceptible to electromagnetic interference, so by twisting these pairs of cables together, it helps to cancel out some of the interference which works on the lines. Doesn't work. 100% doesn't work as well as using light to transmit information. But it does help us to be able to increase the speed across these cables
02:00
and to make these cables longer than if they didn't have any twists it all.
02:04
When we're talking about twisted pair, we may hear of S T P versus U T P S T P stands for shielded twisted pair. It's essentially a
02:14
cable that on the inside of the outer coating on the insulation, it has additional braided shielding, which helps
02:21
protect those twisted pair cable ings from electromagnetic interference. So we have our outer rubber coating with a shield on the inside, and then our twisted cables are untwist it pare ru tp. It's only going to be that outer coating with our inner twisted cables. So ar STP gives us a little bit more protection,
02:40
but it isn't
02:42
as typical was just saying a standard. I'm plugging my computer into a router type environment would be more using our unshielded twisted pair because our UTV will get the job done,
02:53
um, and not be as expensive as the STP, the shield of twisted pair and isn't gonna be his bulky either.
