We just leveled up HARDCORE - Fibre Adventure

How did I end up at the top of the ladder? - Oh no, help me Jake, I'm stuck on top of the shelf. You're going to have to take the ladder and climb it. He can't resist the damsel in distress. - The damsel, oh boy. Damn incel. - You know, in fact I'm not celibate. You have met my children. Oh yeah, that sounded worse than it was. - (laughing) that sounded very strange. - Yes, no, not like that. (both laughing) Are you ready? - Yes, give me that. - Oh God. - That wasn't very elegant. - Agree, hold.

We can do it with more grace than that. Hey, hey, hey, it's okay. It's not elegant, but it works. If it works, I twerk, you know? Can I scale it this time? - Oh, do you want to come up here? - Yes. - It's okay, if I go down I won't come back up. You have a lot of time on your arms, right? - Yes, I don't know if I would describe myself as a long-armed boy. -Hey, you better be careful with that sprinkler, okay? - Yes, yes, I'll try not to hit him too hard. This is very unpleasant. - It is not like this?

Doesn't it stink? - Oh Lord. Luckily, my t-shirt is also LTTstores.com. It's not sweat from effort, it's like sweat from stress. Like really stinky sweat. I'm like Tom Cruise. - Oh Lord. - I am a short man with a big ego. I mean I do my own stunts. - There is one more grievance that we did not talk about earlier in the video, and that is that you cannot get the end of these cables dirty. If there's any speck of dust or sweat or whatever... - Grease. - Grease stuck to the end of the ferrule, which is at the end of the fiber cable, can block signaling and cause a non-functioning connection.

Fortunately, our friends at Fluke sent us one of their certifiers. This is like a $20,000 fiber tester. - Thanks Fluke. - Thanks Fluke. One of the most interesting features of this is its fiber inspector. It's essentially like a little camera that you can place on the end of fiber cables and look directly at them to see if they are dirty and it will even do a test to make sure the cable is clean. To some extent, I suppose. - And you can even put it on your butt. I mean, technically that's a characteristic of almost anything, if you try hard enough. - I mean you wouldn't really see anything.

It is very expanded. We have our tests set up as fiber inspector, that's what we want here. - So I

just

stick the thing on the thing? - So yes, did you remove the dust cap? - Yes. - Glue it all the way down and then that ring there to focus. Keep going, keep going, keep going. Keep going, keep going, stop. Now that it's in focus, we can analyze and we can see that there is only a small defect, but it is within specifications and it is fine. It's great, they even show you around the area.

So right in the middle you can see the little white spot. That's actually the light coming through the fiber from the other end. If you took a stylus and shined it up there, you would have a very, very large white spot. The actual glass part is

just

this inner ring. And these are all just additional parts that are around him to protect him as part of the pharaoh. It's really expanded. For reference, the part we're looking at in the middle is only 62.5 microns. That's small. - I guess I shouldn't investigate this, huh? - It's not that strong. - Is it a laser? - Not precisely. - Ah OK. - It's a light. - How are we doing? - Well, that one is a little dirty.

So let's clean this one up. - He is a dirty boy, very dirty. - Now you might think I'll just leave it. - Yes, and wipe it with your shirt. Try wiping it with your shirt. Or maybe you have a tip, I probably have some good Linus juice now. (Jesse laughs) Now, luckily, we have a little cleaning pen. That's probably good. Well. The more you do it, the more static it will become and it will probably get dirty. - Alright. - From what they told me, you normally do it once and if it's not enough, then you do it a couple more times. - Wow, look at that. - That's pretty neat.

So there are still some specs off the middle, but it really shouldn't matter. Yes, it still happens, we are ready to go. - Does this thing work as if it were a cleaning object inside? - Yes, there is something antistatic like a cleaning towel in there. A fancy little piece of thread. - That is incredible. Okay, and then we'll hook this guy up. Wait wait wait. - No, no, we have it, we have it. - Come on honey, yes. - Okay, you can do it. Oh yeah, she's good. -Got it, wow. - Nothing bad. - Is it clean. - How are we going to achieve this? - Yes, I wish I had done it differently. - Oh no.

Oh no. We have to clear all this up. That's a pretty tight hole. Oh, the top one is a little looser. Wait, Wait, Wait, Wait, Wait. - Hold the door. - Yes, you're fine. - Hordor. - I don't want things to get too bad here, you know? - Well. - Alright. - Well, the last thing we will do to verify that our link is still working is a loss test. This will basically ensure that we don't have too much signal loss over the length of our cable and can also certify it for the specific application we are going to run.

Not only is it going to tell us that two 15 meter cables that are coupled together have this specific amount of loss and that's within the budget, that's good. It is also going to certify it, let's say for one hundred gigabits. So we'll say, yes, we want this cable to be able to deliver a hundred gigs, and it will tell us if, based on the coupling we have, that's an appropriate amount of loss. Well, we're going to need two split limbs there, you know that right? - Because? - Because we have two different computers. - Oh, that makes sense. - Fictional.

Alright, so we're going to do a hundred concerts and we have a connection in the middle, right? We have a coupler. And then we have the two air gaps at each end, which is where our reference cases will connect. - Man, an accidental cut in the fiber at this point would not be a good time. Please no. There is a better way to do this, but we are not doing it in a better way. - It's going to fall from there. - What, it's not going to fall. - Yes, it probably will. - It will not.

How is it going to fall? It's everywhere. Okay, taking off the tape doesn't count as falling off. - Well, I just left (bleep) now that you told me to. - Yes, but you're like (makes noises). You can move it. - We should have wrapped it completely. It's an extra effort to specifically make small pieces. - Yes, but it saved tape. - And we are within the specifications for a hundred concerts, even though we only do 25. - Oh, great. Alright, how about this one? - Our loss is a little bigger than I expected, but our limit is 1.9 DB and our loss is only 0.4.

I guess it might be a little dirty on this end because we didn't clean it first. But it is within our margins. Then we are fine. Success. - Nice. Well, that was a lot of learning, but don't worry because next time at LTT, hopefully in a week or so, we'll finally have all of our editors here in the edit room refreshed and connected. on our fiber with our new server which we will call new Whonnock server. - It's Whonnock 3. - New, new Whonnock. - It's Whonnock 3. - And we'll use it to test the performance of the setup, to see if all this work was worth it.
