LAN Technologies: Base T This lesson covers the Base T standard. A Base T standard is what categorizes a network and tells us what its base standard is. Base networks give us a means to describe the speed, medium and the distance limitations of our network. These standards are good to know when documenting a network and also useful for the network plus exam. The different standards are:

  • 10 base T
  • 100 base T
  • 1,000 base T
  • 100 base Tx
  • 100 base Fx
  • 1,000 base X

This lesson also discusses the following fiber networks: - 10G base SR

  • 10G base LR
  • 10G Base ER
  • 10G Base SW
  • 10G Base LW
  • 10G Bae EW
  • 10G Base T
Video Transcription
00:04
So when we're talking about our land connections, we're talking about our land network standards were commonly gonna hear what we refer to as our ex base X networks. Now, when we're talking about our base networks are 10 based TR 100 based t were essentially categorizing our network.
00:22
I'm talking about what it's meant. What it's based standard is on our network.
00:27
What is the what is the speed that we are going to see on our network, depending on what type of connections and or what type of network interface cards, What type of cabling and what type of distance were using on our networks now are based. Networks allow us a very quick and easy way of describing
00:46
the speed
00:47
medium, as in what type of cable were using and the distance are the distance limitations of our network. So
00:57
these air good to know just for when your divine designing and documenting your own network. And if you are looking to take the network plus exam, these are different standards that you'll need to memorize, because you may be asked to identify what a certain speed would be for a certain based network. So let's take a look
01:15
over here we have Ah, starting off our 10 based T network. Now, one of the first aspects of this 10 based, whichever we want to take a look at,
01:27
is going to be the number that we have at the beginning. Now the first number, the 10 is going to tell us that we're gonna be running at 10 megabits per second.
01:38
Now with our tin bet, Megabits per second are 10 megabits per second network. If we know about our different cable types of different Ethernet cable types, we're going to need a cat three
01:51
Category three cable Ethernet cable minimum. We talked about how our Ethernet cables have different categories on, and those different categories transmit over different frequencies over those cables. So we need to be aware of what type of
02:07
what type of wavelengths, what type of wavelength, what type of frequency can travel over those cables.
02:12
So we know which network interface cards to get to interact with. Those cables were getting a 10 based T network interface card. Then we would want to use at least that cat three cable.
02:22
So we're gonna be a 10 based T is going to be a cat, three
02:25
at 10 megabits per second and the maximum distance for our cat three cable, and thus the maximum distance for 10 based T networks are going to be 100 meters. So 100 meters per single cable segment from one device to the next.
02:42
So any time that we're looking at our 10 based whichever networks and we see a T at the end,
02:50
that tea is going to indicate that we're using a some sort of cat cable, whether it's a cat, three cat, five cats, six cable that t at the end is going to let us know that we're using an Ethernet cable. A remember, are you t p r unshielded twisted pair.
03:07
So we're using a T cable, a twisted pair
03:10
cabling.
03:12
So we have our cat three minimum 10 megabits per 2nd 100 meter maximum on our 10 based E. Next we have our 100 based T. Now are 100 based T Standard isn't really a standard by itself, but really, it's a category of different standards When we're talking about our 10 based T networks who may be referring to
03:31
our 10 based T too
03:32
our 10 based T four are sorry are 100 based T to our 100 based T four are 100 based teat are 100 based T X. So it's a category at sort of the baseline for several different standards that we may encounter and our networks. So that 100 based T.
03:49
It's sort of the main category. And if we're actually designing a network, will actually have some sort of 100 based T something
03:57
network that we're encountering.
03:59
Next we have our 1000 based T networks. Now are 1000 based T networks are going to run over a cat five e
04:10
at one gigabits per second
04:13
over again 100 meters because that's the maximum distance for our tea cables are twisted pair cables.
04:20
Next we have our 100 based T X, and this is going to be a cat five e minimum 100 megabits per second,
04:29
100 meters. So remember So again, this 1000
04:34
almost is helping us see how many megabits of data were transferring at once. If we have a 1000 base network than its 1000 megabits, also known as one gigabit,
04:47
so are 101,000 based. T is going to be cat five e minimum one gigabit per 2nd 100 meters and are 100 based. T X is also gonna be cat five e, but it's going to be running at 100 megabits per sec, only 100 megabits per second because we have that 100 based T X
05:05
and still over 100 meters maximum.
05:10
Next, we have 100 base FX. Well, we have a 100 base FX. That's not our tea. We aren't using our twisted pair cabling anymore. So what are we using in a 100 base FX network? Well are 100 base F X
05:24
is going to be multi mode fiber
05:27
and you see we have that f there. And so that's Consort, that consort of help tip us off. But we will use some other letters in our fiber networks as well. But do you know that are 100 base FX is our multi mode is going to be a multi mode fiber
05:42
transmitting at a maximum speed of 100 megabits per second again, that 100 at the beginning,
05:47
and because it's multi mo fiber weaken. Our distance can go up to two kilometres, so we've severely increased the amount of distance that we can go.
05:59
Then we have our 1000 base X now are 1000. Base X is going to be another similar to our 100 based t were. Really. It's going to be a sort of a category of of different connections, a category of types of networks that we're going to run into a category of based networks that will run into
06:18
our 1000. Base X is going to be also known as our IEEE
06:23
802.3 z standard. Remember, all of these are out are under our Ethernet standards. All of these are different based networks under our 802.3 ieee 802.3 Ethernet standard.
06:38
So our 1000 base X is going to fall under IEEE 802.3 z.
06:45
And this is going to be what indicates different types of gigabit network connections. Eso remember our gigabit is going to be a a 1,000,000 billion bits per second over a connection and it's going to be over either copper or fiber
07:01
and it could have varying distances because gonna be over copper or fiber. But again, it's another category of different based networks.
07:10
So now we're gonna move on to some or of our fiber networks next that we have our 10 g base s are. So now we throw in another component. We're not just doing 10 10 101,000 base letter were are doing 10 G.
07:28
And as you can probably guess, that G is going to stay in four
07:31
gigabit. So if we're running on a 10 G based network, that means our maximum transmission speed is going to be 10 gigabits per second or 10 billion bits per second. So 10 G base s are now 10 G base S R is going to be another multi mode fiber,
07:50
but this time we're gonna be running at 10 gigabits per second
07:55
and we have a distance of either 26 meters or 82 meters, depending on which exact specifications were running on this network. But remember that we can run at either 26 or 82 meters for 10 G base s are depending on what type of medium we have,
08:13
and then we have our 10 g base L R R 10 g Base L R. Is another going to be another 10 gigabit Ethernet,
08:22
and it's going to be running on single mode fiber at 10 gigabits per second. Max now are 10 g base L. R. Is going to be to give us a maximum distance of 25 kilometers on a single link. So that's going to give us a lot of distance to push out,
08:39
Um, and
08:41
is gonna be again. We see why we need to use a single mode fiber. We see one. We need to use a fiber optic cable to go from one point to another if we're on this 10 g base L. R. Because 25 kilometers is way outside of the range that a standard U T P
08:58
or even a shielded twisted pair cable can handle on a single cable length.
09:05
So next we have our 10 g base e r, and this is again going to be single mode fiber, and this single mode fiber strand is going to be 10 gigabits per second. But now we've bumped it up to 40 kilometers. So these are L R E r.
09:24
Even R S R L R E r
09:26
A lot of our different five or connections Now that we're just gonna be talking now that we're in our 10 G based networks, there's
09:35
really, to put it bluntly, if you're going to know these and be able to identify him, this is one of those things and computers where you're gonna just have to kind of memorize. You're gonna have to say Okay, the E r is
09:48
single mode. Bible fiber. 40 kilometers L r a single mode fiber. 25 kilometers Essar's multi mode fiber 26 meters or 82 meters. So flashcards charts repetition, memorization, Little jeopardy Games that you create using PowerPoint slides
10:05
are all great, all great ways to memorize thes but
10:09
nonetheless,
10:11
our 10 g base E. R is going to be single mode fiber 40 kilometers. Now we can see with our 10 g base l R and R 10 g based E. R. Especially we have the potential for some serious backbone network connections. Here, 25 kilometers and 40 kilometers is a very
10:31
long distance compared to 100 meters,
10:33
so we can lay some serious backbone network infrastructure that can carry a lot of data very quickly. 10 gigabits per second. So this isn't going to be your run of the mill Typical inter office connection. This is going to be backbone long distance connective ity typically,
10:56
and the next that we have our 10 g base s W now are 10 g base s W is going to be back to our multi mode fiber, 10 gigabits per second. But on Lee, a maximum of 300 meters.
11:07
Now we're keep in mind, remember, Are the difference between our single mode fiber and our multi mode fiber we talked about in our earlier modules where we talked about our different Ethernet mediums are different network mediums. We talked about the difference between our single mode fiber and our multi mode fiber are single mode fiber is typically going to be
11:28
shooting a
11:30
the is going to be a laser die owed, whereas our multi mode fiber is going to be able to transmit multiple signals at once. But it is going to use a typically like an l e d d. I owed in order to send the signal and are single mode fiber is notoriously able to go
11:46
along a lot longer distance than our multi mode fiber is,
11:50
which, which makes sense are single. Most fiber is going to be Maur dedicated connection to one single beam of light so it's gonna go farther. Are multi mode. Fiber is going to be more concerned with having a lot of data that it can transmit. At the same time it's going to go short. Shorter distance
12:07
so single mode fiber, long distance, multi mode fiber, short distance.
12:11
So speaking of single mote fiber, we're now down to our 10 g base L. Our network are 10 g base L. Our network is going to be single mode fiber,
12:22
10 gigabits per second
12:24
and 10 kilometers maximum.
12:28
Then we have our 10 G base, E W,
12:31
another single mode fiber, 10 gigabit bits per second
12:35
and back to 40 kilometers. So our specifications for our 10 g based E. R and R 10 g based E W are very similar, with both of them being single most fiber, 10 gigabits per second and 40 kilometer max.
12:50
And then lastly, we have our 10 G based team back to our twisted pair cabling on entire board filled with a fiber cabling over here are 10 g based T is going to be a Ethernet 10 gigabit standard,
13:05
and we're going to need at least a cat six or cat six
13:11
a cable, and we're gonna run at a 10 gigabits per second standard. And we're going to be able to push if we're running a standard cat six cable at 55 meters. But we're running cat six A. Than we can extend that cable out to 100 meters per cable segment.
13:28
So
13:28
just remember, our main points for our different based networks here are that these are all under our 802.3 Ethernet standard, and they all specify a distance, a medium and a a certain speed that they can max transmission speed that they're transmitting over.
13:48
So
13:50
again, these different based networks are really something that you're just gonna have to memorize if you don't work with them every day, you're gonna have to create charts, create flash cards and just go through them and memorize them, especially if you're preparing for a test. But
14:05
with RePets, with the more repetition you do, the easier they'll be, too. Remember, maybe go through this video a couple times to get the hang of them, and then once you do, you'll be able to go through him. But just a couple of key points. Remember that our T networks are going to be twist that same for twisted pair. So we're going to be using a some sort of cat standard,
14:24
and then our FX
14:26
S R l R E r S W l W E w Anything that doesn't have our tea standard in it is typically going to be our fiber cabling.
