hey there networking pros in this video we’re going to talk about using fiber optic components to extend your local area network into another building or in a sense create a campus-wide Network now in the last video we talked about the fiber optic components and if you didn’t see that video I’ll leave a link here for you so you can go see that one first and then come back to this one. In this video we’re gonna do a real world application. So you’ll remember I talked about transceivers and fiber optic cable. So in building A we’ve got a switch.
And this yellow wire right here represents the the internet service that comes from the outside world.
So everyone in building A has got access to not only each other’s network resources but they’ve also got access to the internet. Over in building B we have nothing at all. Right? So what we could do is get a couple of matched transceivers. So go on one of the popular auction websites.
But if you want to buy brand new that’s fine too. I’m a little bit of a believer of using the auction website first just because the enormous cost savings so I got a couple of matched SC multimode transceivers and then I also got a 400-foot let’s pretend it’s 400 feet I got a 400 foot multimode fiber cable and then I connect the two buildings with the multimode fiber optic cable so as I’m connecting the two transceivers right then the transceivers also have an Ethernet port on them so if you don’t remember that from the last video I didn’t really spend a lot of time talking about but see it’s got an Ethernet port on it a copper Ethernet port I’m going to patch that in to the switch now some switches will come with or you can get switches that come with the transceiver already built into the end of the switch so the fiber transceivers already built in but if you don’t have that you can just get the transceivers pass them in add a switch to building B where there wasn’t one before back to transceiver this way voila I am now sharing network resources plus don’t forget the internet with all the people in building a and all the people in building B so if only it were that simple the elephant in the room here is how do I get this fiber-optic cable from building a to building B it’s a couple ways you can do it in fact there may be more than two but it’s either to go underground or it’s exit the building dig a trench lay conduit and then come back out and go into the side of the building that’s one way to do it the other way you can do it is with an aerial cable aerial cable you see involves putting some kind of a reinforcing line in first you can’t just simply run the cable through the air I mean you could but it probably wouldn’t last for long because what happens is there’s gonna be a lot of tension here the fiber-optic cable itself is not designed to endure that tension so you need to either buy a cable that’s got what’s known as a messenger wire already built in it and the messenger wire is like a steel braided cable that takes the stress or the other thing you can do and this is what I’ve done when I’ve done the installations and I’m not an expert but I’ve done a couple of these is I got steel braided cable and I ran it from here to from building a to building B and then I put one of those flex conduits that kind of those three-quarter inch or 1 inch plastic flex pipe conduits I strat I secured that to the the braided cable and then I pulled the fiber-optic cable through that there’s a few things you need to know if you’re gonna buy fiber-optic cable usually I recommend buying it pre-made what I mean by premiums mean that the ends have already terminated it is possible to do terminations yourself you can buy the kit the kit is anywhere from one hundred to several hundred dollars to take the raw cable and put the ends on it but in my situation what I’ve done is I bought the cable pre-made and you can get cables pre-made to lengths and I’ll show you in a minute on the end of the video some different resources some pictures of the things I want you guys to know about so that you can make make wise decisions about purchasing the cable so those are things to consider it’s easy to do the transceivers it’s easy to buy the cable it’s the tricky part is getting it from building a to building B now let’s switch over and talk about some of the other things you need to consider all right if you remember I said you can get premade cables to lengths most of the supplier websites the good ones usually come with some type of a configuration tool where you can go through and say okay I need this type of mode cable I need to put this kind of end on either side it is possible you could have situation where you would have you know an SC on one end and LC on the other dependent on your equipment then you can specify the length anyway so you go through this whole exercise here and finally at the end it can it can tally up the price for you all right so that’s one way to do it the other thing you can do is click on the auction websites you may find premade 400 500 600 foot cables it’s okay to have something that’s longer than what you need you just need to spool up the rest on either end I’ll show you a few pictures from installs I did I am NOT an expert so some of you who work an outside plant all day long may have lots of criticism feel free to share so we can all benefit this is an aerial installation I did between two industrial buildings that were about 200 feet apart that orange thing you see going through the middle of the screen that’s that flex conduit I was telling you about and it is attached to a steel braided cable and let me zoom in here a little bit you can you can see that a little closer so this guy right here this is a steel braided cable attached to the building and then the Flex conduit exits building a few inches below that there’s a bunch of silicon on the other side or we’re actually on both sides to seal the from weather and then it’s attached to the steel braided cable these little these little rectangular things here those are buckles that that secure the cable on either side and then there’s the other end of the cable going into the into the building I know it looks like there’s another cable there that’s not mine that was a some kind of a aerial cable that the the bail company had run many moons ago and it didn’t even have a messenger wire in it so but I left it alone and then here’s some indoor installation this thick yellow stuff here is actually multi strand fiber so they think there’s I think there was 12 or 6 different strands in there but anyway this is armored that’s why it’s kind of thick and this is the way the slack is stored see how it’s in like a doughnut shape they make little plastic Donuts that you can get to put on the wall to store your slack and that’s common with fiber because like I said it’s pretty common to get premade fiber cables so you’re gonna have slack on either end and when you when you want to coil up the slack you want to have that nice wide radius like that and then this is a breakout box for that same cable so okay I guess it was only it was only three pair so it means there’s six different cable strands so that’s a cable breakout box it’s it’s almost like a patch panel for cable I guess and then there’s a smaller one again another another three pair right there alright so I hope that helps you out I recommend you do lots and lots of research if you decide to take on this endeavor yourself and if you’re gonna run an aerial cable especially with that steel braided cable be very careful alright thanks so much for watching see you next time
