ah right oh okay i'm like tom cruise oh my
god i'm a short man with a big ego i mean i do my own stunts this this is
copper networking cable copper's lame
this this looks nothing like the network cable in your house
why because it carries data using light
that's right ladies and gentlemen it's finally happening i have been chasing
the perfect networked video editing setup since before i even founded Linus
media group and the reason is simple it
is a massive pain in the scrotum to toss
around external drives use google drive or whatever it is that regular people do
to share footage across multiple team members
and when it's done properly
network storage also helps protect your valuable data in the event of a drive
failure now this project has been a huge
undertaking but we learned a ton
and we're going to be using the light from your monitor to network that info
straight into your brain world interface
that's right we're going 25 gigabit to every one of our editing workstations
100 gigabit to our servers and we are
telling you guys all about it
holy wait really are we sponsored by
solidworks wow holy to that too
are you feeling stuck on your current project or waiting for your prototype to
come off the 3d printer don't waste that time you should be learning from
industry pros who make products using solidworks every single day this year's
3d experience world is online and it's free to attend check it out at the link
in the video description
before we talk about the how of installing and using fiber it's
important to understand why fiber is even necessary in the first
place in both copper and fiber optic cabling information is transmitted by
changes in energy at a given frequency with copper Ethernet like rj45 cables
the conversion of these changes in electrical energy to actual data on
either end is handled by the device that you're plugging into
that's why the devices tend to be expensive and the cables tend to be
cheap in the case of fiber optics the cables
and devices can be relatively affordable but the transceivers which are used on
both ends to convert the changes in light to data can be an absolute money
pit it's also worth noting here that your switch or network card can be fussy
about the brand of transceiver you use kind of like printers that require
pricey first party ink fortunately all of our gear got along nicely
without getting into too much detail about the nerdiness that is cable
signaling the main advantage to fiber optic cabling is that it can carry a
signal over a much greater distance and
at a higher frequency this is thanks to the very low signal
power loss incurred by the glass inside the cabling itself
it also has much greater resistance to interference because the light inside of
a fiber optic cable isn't really susceptible to electromagnetic
interference from heavy machinery or electrical lines etc
now it's not that copper cabling can't do high speeds even in our server room
we have copper cables that run 100 gigabit
but those cables are usually limited to about 5 meters and if you move up to 400
gigabit Ethernet yes that is a thing the longest copper
cables you'll see top out around 3 meters or 10 feet that's nowhere near
long enough for our editors to plug in so we knew we needed fiber but
fiber is the kind of rabbit hole where there's lots of documentation out there
but all of it is designed for people who already know everything about it do we
need single mode or multi-mode lc or sc
simplex or duplex om3 om4 om5
so here we go the two main types of fiber are multi-mode and single mode and the main
difference between them is the size of the core which is the actual glass that
transmits the optical signals while single mode uses a very thin core
isolating the light to a single beam multi mode has a much larger core
allowing the light to reflect back and forth within it
this allows multi-mode fiber to send light along several different paths or
modes at the same time however when it comes to longer distances the multiple
paths of light can cause distortion at the receiving end making it less ideal
for applications like that in practice multi-mode is usually
reserved for up to about a hundred meters which means that inexpensive led
or laser sources can be used to send light down the glass
anything greater than that let's say 10 20 40 kilometers is typically single
mode and requires much more expensive solid-state lasers
this means that for our application going from here to here we could use
single mode but that would be really expensive and kind of stupid
next up we've got the type of connector or termination lc sc fc st etc
this one really comes down to your application or preference the 25 gigabit
transceivers that we're going to be using from fs.com by the way
thanksfs.com use lc fiber connections so
naturally that's the type of cabling that we went with you can easily adapt
between connection types so if you get the wrong cable it's not a huge concern
but there is one big note here re-terminating fiber cables in the field
can be very expensive and time-consuming
so whenever you can it's best to use pre-fabricated cables like what we got
from our friends over at infinite cables thanks bros
then there is simplex versus duplex
light can only be sent one direction at any given time so in most cases any
fiber link is going to have two cables one for transmitting and one for
receiving this is called duplex fiber
however you can also get simplex fiber
and run by die or bidirectional transceivers which make use of multiple
modes of light each to send and receive
over one cable these transceivers are much more
expensive though so they're not much use to us but in the data
center by eye can be used to increase density in fixed size conduits and patch
panels and can also help with cable management
then there's the category of cabling for
multi-mode there's om1 all the way through to om5 with the primary
difference being the bandwidth and distance capability of each generation
we went with om3 because it's cheap ish
and has ample range for the relatively short runs to our editors
so okay multi-mode duplex lc connector om3 fiber
say that three times fast but enough of talking headlines let's take a look at
the actual deployment and maybe we'll even run and test a cable
usually when you're working with this ultra thin stuff it's to save space in
your conduit so that you can run more cables but we were mostly concerned with
fitting the boot of the wire inside of our electrical boxes you'd also usually
run it in conduit or by cabling with some kind of shielding or protective
cover but it's just gonna kind of hang
out up in our drop ceiling so we weren't worried about the cables getting damaged
over time and even if one did we did run
copper to every station just in case and
the server room happens to be just on the other side of this wall so
it's not like we'd have to go very far
so from each of these keystone jacks right here ah there we go each editor oh
thank you Jake we'll have a small patch cable like this running to the 25
gigabit nick in their system shout out to melanox for providing those by the
way we did a full video showing off their blazing fast speeds recently and
then each of these will be protected by
here we go there we go a small bit of split loom while the
fiber lines in the office were run professionally there's one that we
kind of forgot to do the one that goes from the server room here around where
the camera guys sit to overhear our ingest station some of our
camera operators got a little dvd about using the mac minis so we're
back to pc and what we discovered is that running 10 gig with two red megs
plugged in actually saturates it so
ed was like hey can we have a fiber connection we were like hey
we got you covered so the only thing here is we're working with like the extra scraps from that
install so we might have to like couple two cables together
but it's actually like fine fiber is really easy to couple so how should we
start this do you think i guess we have to start on one end yeah kinda so we already have
wire mold that runs across all the way down to here
but then it pops back into the wall like right there for some reason oh weird so
i guess we can have it come out of here and then we'll just like tape some split
loom to it i think yeah okay blue loom is like this corrugated plastic stuff
that's split and it's a wire loom so you put wires in it to sort of protect them
or keep them organized in the case of fiber you like don't want people to damage it is there
a reason this computer goes backwards
i think if we have the split loom come up we can like tape it or
LTT Store cable tie it to like right here and then just a little bit of fiber
will come out i absolutely hate everything about what i'm looking
at right now you got to be gentle with this stuff eh i will i know but it's not
it's not easy what are the odds this fiber cable still
works by the time we're done i give it at least eighty percent eighty
percent yeah and you want that to go into the cable
dude adam and jig there yeah oh my god we have to move the shelf how the hell
are we gonna move the shelf three two one
oh man um that should probably be enough
hey okay all right all right here i'm gonna pass this up to you well should i
just like climb on the shelf i guess i i don't know how how strong you think this
pebbly case is very
oh wow there's like a open wall socket here
you should probably tell Yvonne about that i think this is a fire bell are you
gonna take this at some point what hello hold on i gotta tell you
vaughn about this hi oh watermelon sugar
okay you're still good you're still good
are are you gonna start putting it in there i mean i don't know a little bit
i mean okay that's about the right
length i think i don't think this shelf is going anywhere so i'm just gonna oh
okay i'm on the shelf now yeah good i guess
um are you all the way to the top
it's not it's not quite it's a little warm
i think that's good enough for now okay where's the oh geez
oh gosh some people use ladders i think you should just climb up here to do this
whole part all right i'm just gonna throw this over there oh wait we were supposed to do two two why two uh
because there's two ingest stations going here all right all right get on back down there well why do i have to
get down there because you're the little one i'm gonna tape this one up here
hold on and just pass me the roll of tape uh nope hey can you pass me the
roll of tape can i can you wait a second
zoomers man they're so impatient damn
boomers they're so slow your mom's a boomer i don't even think
she is i drop the tape are you there you want to open up the thing yeah you wanna
pass me the thing well you gotta open up the thing first don't give me the thing
first how about fine here here's your thing
i can't believe we're running fiber straight to the backs of the ingest
stations this is kind of crazy what were you thinking instead
i just thought they'd run Ethernet where's my fiber in my office
okay now climb up here and do your thing let's
sometimes i wonder who's actually in charge here
okay it's not gonna fall right can you hold it i'm i'm holding it right now
i'm holding it braced against this one you're fine plus this one is like in the way so it's
like fine oh god
okay all right i'm gonna i'm gonna get down now you have fun up here
see you later maybe we should have tested these cables before we put them in there yeah it probably wouldn't have
been a terrible idea i need some tape or you're just closing it oh yeah
just gotta not pinch it too hard there we go
man i'm like the pinch off king is that what you told me i'm pinching off the
thing here i'm lightest tech tips hi i'm coming to you from the top of the shelf
uh we got some great news up here the lights are the lights are they're warm
but they're not hot you know it's too hot up here with my LTT Store stealth
hoodie you know why he wears the toque so he doesn't have to do his hair
exposed hashtag Linus i think i need
like a flathead or something uh you have keys on you uh yes
oh you do have a knife yeah that's enough what is the cycle
it's a ladybug i don't want to break the knife yeah why
don't we use let's use the flathead uh very graceful dennis well no that was
my keys that wasn't me yet oh god uh
where is it there it is okay there we go not so bad so how far are we
going to make it here we might make it like pretty much to there most of the
way which is good actually because then if the coupler i'd rather the coupler not be in the wire mold yeah okay wait
how did i end up on top of the ladder oh no Jake i'm stuck on top of the shelf
you're gonna have to get the ladder and climb the ladder he can't resist the
damsel in distress the damsel oh boy
damn incel you know for a fact i'm not celibate
you've met my children oh yeah that sounded worse than it was
yeah no no not like that
you ready yeah give me that oh god
that wasn't very graceful okay hold on we can do more graceful than that
right all right oh okay not graceful but it works if it works like twerks you
know can i can i climb it this time oh you want to go up here yeah uh if i come
down i'm not going back up you got long arms right um yeah i don't know if i'd
describe myself as a long-armed boy you better watch that sprinkler all right
yeah yeah i'll try not to punch it too hard this is very unpleasant isn't it
doesn't it suck oh my god oh
hey fortunately my t-shirt is also LTT stored
it's not exertion sweat it's like stress sweat like the really stinky sweat
i'm like tom cruise oh my god i'm a short man with a big ego i mean i do my
own stunts there's one more grievance we didn't talk about previously in the
video and that's that you can't get the end of these cables dirty if there's any
speck of dust or you know like sweat or whatever grease grease stuck on the end
of the ferrule that's at the end of the fiber cable it can actually block your
signal and result in a connection that doesn't work fortunately our friends
over at fluke sent us over to one of their server fibers this is like a 20
000 fiber tester thanks fluke thanks fluke one of the coolest features with
this thing is their fiber inspector it's essentially like a little camera that
you can stick on to the end of fiber cables and look directly at them to see
if they're dirty and it'll even do like a test to
tell you for sure that that cable is clean just some standard i guess and you can
even put it up your butt i mean technically that's a feature of pretty much anything yeah we try hard i mean
you wouldn't really see anything it's very zoomed in we got our test set up as
fiber inspector that's what we want here i just test stick the thing on the thing
so yeah did you pop the dust cap up yeah stick it all the way on and then that ring there is to focus
keep going keep going keep going thank you guys stop
and so now that it's in focus click analyze
and we can see that there's only one tiny defect but that's within
the specification and it's okay it's cool though they even show you the
zone so like right in the middle there you can see the white little white speck
there that's actually the light that's coming through the fiber from the other end if you were to take like a light pen
and shine it up there you'd have a big big white spot the actual like glass
part is just this inner ring there and these are all just extra parts that are
around it to protect it like part of the ferrule it's really really zoomed in for
reference the part that we're looking at in the middle is only 62.5 microns
that's tiny i guess i shouldn't look into this eh ah it's not that's a little
laser not really oh okay it's a light how we doing well that one's kind of
dirty so we're going to clean this one dirty dirty lad now you might think i'll
just give it a yeah and clean it off with your shirt try cleaning it with your shirt or maybe
your toque it's probably got some nice Linus juice on there
now fortunately we have a little cleaning pen
that's probably good okay the more you do it the more like
staticky it gets it's probably just gonna be dirty um all right
from what i was told usually you do once and if it's not enough then you do a
couple more wow and look at that that's pretty clean so
there's still some specks outside of the middle part but it shouldn't really
matter yeah it still passes we're good to go does
this thing cycle like a cleaning thing yeah there's like a little anti-static
like cleaning towel thing in there a little a little piece of fancy string
that's sick okay and then we're gonna plug this boy
in
oh no no we got it we gotta
on baby yeah okay ah you can do it oh yeah she's good
got it whoo nice not bad it's clean
how are we gonna oh yeah i wish we had uh
that's a pretty tight hole oh the top one's a little looser hold hold hold
hold hold the door yeah you're
good i don't want things to get too kinky here you know
okay all right okay so the last thing we're going to do
to verify our link is still working is a loss test that's basically going to make
sure that we don't have too much signal loss for how long our cable is and it
can also certify it for the specific application we're going to run it's not only 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's also going to certify it say for 100 gigabit
so we'll say yes we want this cable to be able to do 100 gig and it'll tell us
if according to how much coupling we have that it's an appropriate amount of
loss but we're gonna need two split looms there you know that right why because we have two different computers
oh that makes sense dummy all right so we're going to do 100 gig
and we have one connection in the middle right we
have one coupler and then we have the two air gaps at each end which is like
where our reference cables will connect man an accidental sniff on the fiber at
this point would be not a good time please no there's like a better way to
do this but we're not doing it the better way it's gonna fall off now
well it's not gonna fall out yeah it probably will it will not how's it gonna
fall out it's all over the place okay just taking my tape off does not count
as just having it fall out stop now that i've you know yeah but you're like
like you can move it around
you should have just wrapped it all the way around it's like extra effort to
specifically make yeah but it saves tape and we are within
the spec for a hundred gig even though we're only doing 25 so oh cool
all right how about this one our loss is a little higher than i was expecting but our limit is 1.9 db and our loss was
only like 0.4 i'm guessing it might be like a little dirty on this end because
we didn't clean this end first but it's well within our margin so we're
good success nice well that was a lot of learning but don't you guys worry
because next time on LTT hopefully about a week or so from now we are finally
going to get all of our editors down here in the renovated editing den and
plugged into our fiber with our brand new server that we're calling new new
one x server new new oneic
and we're gonna use that to test the performance of the setup to see if all
of this work was even worth it at all lmao you know what's definitely worth it
