this is less than $7.1 network cables and connectors. Part two,
We're going to continue our discussion. Speaking on the Ethernet protocol, neither net standards and we'll also look at the connections and cables using the Ethernet standard.
Okay, And this lesson we're going to go over and discuss fiber optic cabling, co ax oh, cabling and specifically really drove down to the RG six and the RG 59 which is used on core XO cabling. And we're gonna finish off talking about the D B nine or the Rs 2 32 serial connectors in connections.
You've already heard a lot about fiber optic cabling over the years. Five or optic cabling is the way to transmit huge amounts of bandwidth over long distances, and it's even used in networks. So we're gonna talk about two different modes of fiber optic cabling.
Now, fiber optic cabling transmit Ethernet frames in a very different way than twisted from copper. Cable
fiber optic cabling uses light instead of electricity. Fiber optic cable is immune to electricity problems such as lightning short circuits and statics on the E. M. My connection issues that we found out in the previous lesson.
Fiber optic signals travel much further. Also then twisted copper pair 4000 meters or more, compared with 100 meters on U T. P. So fiber optic is an ideal cabling in a situation where you may have long distances within a building or within a business corporation,
it's ideal when you're connecting buildings together over long distances. Fiber optic cabling again uses light, and we're gonna dig in and see what type of light of a a few more slides. But again, fiber optic cabling carries a huge amount of bandwith in long distances and short distances,
so with fiber optics, light could be sent down. A fiber optic cable is regular light or a laser might, so there's two different lights. The fiber optic cabling uses a regular light like an led or a laser. Each type of light requires a totally different fiber optic cables.
Most network technologies that use fiber optics to use light emitting diodes or L E. D's
too thin light signals. These use mo time old fiber optic cabling now mo time oat fiber transmit multiple light signals at the same time, using a different reflection angle within the core of the cable. The multiple reflection angles tend to disperse over long distances.
So that's why you can't use multi mode fiber over very, very long distances,
and you would use what's called a single mode. So let's talk about single malt cable
fiber optic cable in that uses light uses laser lights, gives me uses a single mode fiber optic cabling Using a laser light in single fiber optic cables allows for high transfer rates over long distances. Now,
except for long distance links, you're not really going to see single mo cabling. The majority of the cabling use nowadays
in lands and lance is going to be multi mode. But for those long distances, it would be single mode cabling a single mold fiber optic cable.
So let's look at the single mold versus the multi mode, and you'll see the image on the left. The singing mode fiber has just a single fiber optic cable, and that laser light passes right through there. Where is multi mode like we talked about before? It's going to send two different signals at the same time,
and it reflects at different angles bouncing through that cable
and on the right. You'll see the singer mole right there in the middle, and that's how that looks on the outside and the more time hold on the far right. Don't, ah, multi mode cable.
Now there are close toe 100 different Ethernet fiber optic cabling standards. 1000 Base S X and 10 gig basis are just a couple. But again, there's about 100 different standards
now. Each of these standards their difference in speed of the network and how they connect
fiber optic cabling will need to connect to a fiber optic switch or a fiber optic network cards. So on the far left that this is a fiber optic switch, you would generally see these and data centers and in large networks where fiber optic cabling has ran throughout. And it needs to connect to a switch just like you would do
Cat five E or cut six.
In the middle is a fiber optic Nick Carr. There's some organization. Some businesses You yourself may even have a fiber optic nick card into a computer. You can run fiber optic directly to the computer. There's a lot of businesses that are doing this because off
the need for more throughput, Maura and faster Internet speeds or connection speeds on the network.
Whether a passing large data files large video or audio files, fiber optic can be wrought, brought right to the system or the PC using a fiber optic nick card. And on the far right, we have a network switch. This is a net regular 10 110 1000 gigabit network switch.
But as you've probably seen yourself over the years,
well, they're starting to come out with the fiber connectors right into the switch. So I would generally use these on the network when I'm bringing in a fiber backbone into the the on the network
and I will plug my fiber connectors right into the switch, then patch my difference network equipment through to switch to wherever they need to go. Well, that's a printer, whether it's going to be PCs or whatever, so you can backbone your fiber optic connection right to the switch.
Fiber networks follow the speed and distance limitations of their networking standard multi promote is slower and has a short arranged a single mode. A typical multi mo network runs at 10 100 or 1000 megabits. per second. Some can go as highest 10,000 megabits a second.
Distances for multi mode generally runs, and they top out about 600 meters.
Sigma Tau, another hand speed and distance, depending on the standard, is faster and longer than multi mo. The top recorded transit Mrs Speed was in 2011 and that was, Ah, 100 terra bits per second, and that distance was over 100 miles.
So let's talk about co axial cable
now. Early virgins of Ethernet ran over co axial cable instead of you teepee either that standards using co ax on no longer use. And nowadays, CO X is traditionally or mainly used for cable motives in satellite connections. Co s is co ax is constructed with a center cable core surrounded by insulation.
This is covered what they shoot a Brady cable.
Now the center core actually carries the signal, and that's that copper core right there. The entire cable was then surrounded by a protective insulating cover, So on the far right, you'll see a cutaway of a co axial cable. In the center is that copper solid copper core,
followed by the insulation for the court and that braiding that was just mentioned.
And the outside is the outside protective covering or they're from shaking the shield. Order the cover for it
Now. Corexit cables are rated using an RG name. There are many RG ratings that that are out there, But for the county a A plus, you only need to know that RG 59 in RG six Both the RG six and RG 59 have a 7 75 home and pendants um RG 59 is thinner
and doesn't carry as much data as the RG six
and the our G rating is clearly marked on the cable. Just like in cat five, you'll see that the RG markings air there now, One way to know or tell the difference between RG six and RG 59 is RG 59 is a little thinner than the RG six. RG six is a bigger cable.
Let's jump into that a little bit more in detail.
So here you see RG 59 on the left and the RG 59. The center core is thinner than the RG six has a thinner insulation and it's lesser shooting whereas on the RG six they have a thicker core for better signal transmission
and a thicker insulation and a better shooting as well.
So let's look at the core axel cabling connectors. We have the F type connector mail, which you've probably seen in your cable installations. There's the F type connector female, and you can see these as in a connector or even an adapter a couple er
and on the far right, you'll see a BNC connector, and being C connector has a twist like 1/2 twist. Turn to connect that to a ah female connector
day. Be nine in serial ports. Older equipment used in earlier type of connection called a serial connection, which used the recommended standard to 32 which is Rs 2 32
Now the serial port was a 9 p.m. d shell male socket called on D B nine or in ours to 32
now there's not a lot equipment out there in the market that uses this. Right now there's 2 32 or d B nine connection, but you're still come across it as a technician working in the field and images below. On the left, you'll see what a Rs 2 32 or a DV nine or serial cable. It's called Multiple Things. How it looks
Now give you a tip
right there in the middle that is, in Rs 2 32 to us. Big cable. That's a good thing to have if you're on the field, because you may come across some of this older equipment. And some of the newer laptops, of course, don't have the cereal or the nine pin connector.
And this is a good way to connect on equipment, right? They're using the USB interface.
I make sure I keep these in my bag at all times
and again. Sometimes you'll come across equipment in your call to troubleshoot or connect to equipment and configure it or what have you and you'll see around the back of that equipment right there on the right. There is a serial port that you would use your cereal cables connect to and again When you connect to that cable, it would be mostly
cereal or Caland command line interface that you do your configuration with.
Okay, so we have finished up our networking cabling in connectors. We talked about the fiber optic cabling
co axel cabling RG six in RG 59 the D B nine in Rs 2 32 serial connectors. So that's it for this lesson, and we will see you in the next lesson.
