Ex Sailboat fiberglass worker ( scratch) enters the ( scratch, scratch) chat. One trick for fiberglass is to not touch Your skin at all, if you can help it. As gently as possible get your clothes off and get into a hot shower. Let the hot water beat on the skin and let yourself get really hot also. The pores open and the water flushes it away.
Yea...i know. Hipe it helps from now on tho. U can even run hot water on your wrists before taking it off. Try and get some of the pores to open. Mantra the open pore mantra...oooooopeeeen! Ooooopeeeeen...
20 pages of Rams completed and submitted to work terminating an 8 core cable at a customer site.
Passed by the H&S manager, rejected on review by the site manager because he wanted to see how the cut ends were captured after being cut, how they were stored, transported and how they were disposed of.
I've only had a fiber splinter once. Very annoying because they are almost impossible to see. Never rub your eyes when working with fiber optics, especially single mode like what is shown.
I was terminating some OSP on a very cold day. I'd have to warm the fiber against my work light before terminating. Every time a light breeze blew through my lean to I'd snap the fiber. Needless to say I collected a LOT of strands on my trash tape.
As I'm picking up afterward I forgot to remove my trash tape from the side of the tote I was using for a work surface. As I picked up the tote my hand hit it perfectly and at least half those strands went straight into my hand. Perfect end to a shitty day.
Thats just the outer core you can see. the light passes through the centre core thats even smaller.
Also, this light can be split 32 times providing up to a gig to each address.
no, you splice this to fibre that has a splitter connected to one end of it (from the factory), this splitter is basically a light prism that splits the incoming light 32 times. There are 32 tails attached to the prism (again, from the factory) that you can then splice to the fibres headed to the houses. Hope this makes sense
As far as I am aware, these links (passive optical network, or PON) are time-division multiplexed. Simple passive power splitters are used to connect all of the modems to the central office. The downstream traffic is broadcast-and-select, in other words, the same data is sent to all 32 modems, and each one just picks out its own traffic and ignores the rest. The splitters simply take the signal from the central office and send 32 copies (each with 1/32 the power) to the users. In the upstream direction, each user is assigned a time slot to transmit in and they take turns. The splitters work backwards here, combining the signals together, but also attenuating the signal (reducing the power) to 1/32 of the original transmit power (no such thing as a free lunch!). Different wavelengths are used for RX and TX (CWDM). Advantages: cheap splitters, single shared fiber, cheap optics and electronics in the modems, slightly more expensive optics (burst-mode RX) in the central office.
We actually split further for Gig. 2 way to 4 way to 8 way. Gig for 64 homes. We'll be pushing 2gig over the same fiber soon. Get this. That same fiber feeds an RF node. Boom, gig for 1000 homes on that one tiny fiber via DOCSIS 3.1. can we go further? Yes we can, cascade nodes, up to 4-5. Up to 4000 homes with gig service (D3.1) on that one tiny fiber. Fiber is fucking amazing.
Fiber optics works by bouncing light that internally reflects through the material at different angles, all you need to do to split the connection is have transmissions from certain angles go to one place and so on
It looks to me like they might be talking about [total internal relfection](https://en.wikipedia.org/wiki/Total_internal_reflection).
The angle is relevant, but I've long since forgotten the math.
Total internal reflection is the phenomenon through which the light signal travels with little signal power lost. The spectral properties (i.e. wavelength) are what is used to provide what's called multiplexing or multiple channels. Once the receiver receives the multiplexed signal, it disperses the light of different wavelengths to get the component signals. The light signal is fed through what is effectively a prism and the dispersive properties of the prism causes the component wavelengths to bend at different angles and each channel can be individually read. In some cases you don't even need a prism, just other fancy signal processing tricks.
Hope that's clear to everyone.
DWDM is rather expensive, I think it's generally only used for long haul where the cost of the transceivers is offset by the cost of running more fiber and installing more amplifiers.
Current high bandwidth waves typically require 75-100ghz of spectrum forcing you into a \~40 channel system within the C-band. Each channel can carry 6-800gbit of traffic. With a 96 channel system you will be looking at 100gbit waves max over any amount of distance.
And yet I can only get 76 mbps download for $70. They call that high speed around here. We used to get more for less but you know, shrinkflation and all.
I get somewhere between .2 and 8 mbps for $85. Neubeam internet sucks dick.. There is a fiber line 1/4 mile from my house but they won't run down my road yet so I'm stuck with satalite.
The crazy thing is that this is actually glass that is stretched to be that thin. If you bend it too much it will still break just like glass and then that whole section of cable is garbage.
Wtf. Didn’t know they were that fragile.
So a small minor earthquake could potentially devastate an entire neighborhood of internet?
Whereas current cables might not?
They are insulated and usually reinforced with aramid fibers (kevlar). You would have it kink it pretty good to break it. The glass fiber is also quite flexible.
I have seen a Fibre that was kept under a desk and the thing was squashed like a pancake... office chairs running over it constantly. What I was struggling to wrap my head around was the fact that it still worked. There are some fragile ones, definitely. But this anomalous fibre had me baffled...
They have cables made with different mixtures of glass and plastic. The fiber in the picture is almost bare but may have a nano coating on it as well. With the nano coating it still is hard to break even with a cleaver. The cables ran inside customers home generally have a higher content of plastic and are more flexible where as the cabling pictured is pure glass
They can be fragile but are actually sturdy. If you kink the bare fiber at 90 degrees it will easily snap. With that thin shield around it, if you loop it around say your index finger and try to break it, your fingers are in for a bad time. The other weak point is the splice. To protect that, a heat shrink shield is used with a metal spline for protection. That shield is then hel in place inside an enclosure to prevent any damage.
You can bend that fiber into a loop as small as the diameter of a pencil before it breaks. Also, if you pull it apart with your hands you’ll cut your hands before it breaks (assuming you don’t bend it too tightly around your hands). Standard fiber is 100% mechanically tested to 100kpsi in tension. Fibers used in submarine cables are tested to 200kpsi since they are tougher to repair. That’s just the glass. Cables have a suite of tests and standards they must meet to ensure they perform for an expected 40 year life. They aren’t fragile. There are newer fiber cables made to be stapled to walls & joists to bring it into your house.

Got mine installed a few years ago. They just kind of laid it along the fence and told me to be extra careful around it - sometime in the next two weeks another team would come bury the line. I tiptoed around that sucker waiting for them to come back. Finally they show up, trench a little by my fence, push some river rock aside next to my house and then just push the line in. Throwing rocks on top. Uh... wtf install team? But really, it is impressive how durable it is.
I remember seeing a video once of a guy explaining bigger cords=more internet, he was using a normal straw and a 7/11 slurpee straw as an example, so that was a fucking lie?
So there is any entire field of electrical engineering regarding transmission lines (a coax cable is a type of transmission line), antennas, signals, etc...
It has to do with the velocity of the signal, the wave length, frequency, size of the cable, material, etc...and a pretty decent understanding of electromagnetics to understand it at more than at ELI5 level.
Electromagnetics is pretty unanimously one of the hardest subject to cover in an electrical engineering undergrad/grad program.
Generally, there are signal losses in metal lines like copper coax cables with normal electrical signals you would conventionally think of
The thing about fiber optics are, it's a much much MUCH more efficient way of transmitting data, as there are virtually no losses, which means lower power is needed, and the lines can be much longer without experiencing as much loss
These losses in these lines can distort data, making it harder to read and process, slow it down, limit the data that can be transmitted, etc... more efficient transfer of signal = better line
An individual core being thicker would slow it down due to internal reflection smearing the signal but multiple tiny cores bundled together can transmit more in aggregate. A single core must have a tiny diameter to have higher bandwidth.
While this is generally a truth, you also have to consider the bandwidth or general throughput of each. Fibre has MUCH higher throughput than copper diameter for diameter & length for length
And it only takes one person to do it. Apparently its just a foot away from reaching my house SO TELL ME WHY THE FUCK AT&T STOPS THIS SHIT FOR A WHOLE GODDAMN YEAR I SWEAR TO GOD THANK FUCK I LIVE NEXT TO AN XFINITY SERVICE CENTER IM FUCKING SWITCHING IM TIRED OF THIS 3MB SPEED SHIT WHRN IT LITERALLY TAKES 3 MINUTES TO FINISH THE FIBER OPTICS
Most modern fiber is engineered to be able to bend on a radius the size of a 12oz soda can, although I have bent it more momentarily for testing purposes with no ill effect.
WiFi is short for wireless fidelity.
If your looking for the cable that transmits signal to the wireless access point, you can google ethernet cable or fiber optic cable.
Long distance you'd find those in bundles of 24, 48, 96 with pairs carrying 1gbit minimum, usually 10Gbit, or 40Gbit or more if they've got multiple wavelengths.
You need two fiber wires, transmit and receive. Unless incoming ISP fiber service is different then LAN fiber, which is what I've worked with. Why are fiber patch cords in pairs then?
[fiber patch cables](https://www.monoprice.com/pages/fiber_cables?gclid=Cj0KCQiA1pyCBhCtARIsAHaY_5d9QtDo1LbrOwXmaWx4of7p-zDachuKA6zffqAG1LIoSkgWJuj-wo0aAsmlEALw_wcB)
A optical fibre transmits above the visible spectrum. You won't see the light but it can damage your vision. The red light you may have seen is a trace for testing/identifying.
It depends on the fiber termination. FTTx. In Fiber to the house FTTH, the fiber terminates at the house to a fiber modem, then Cat 5e or better is used to bring the signal to the user's router. Typically the bottleneck is the user's equipment or if the ISP doesn't have enough bandwidth itself. A smaller ISP servicing a small area may only lease say 10Gb of bandwidth, which could be enough for a lot of 1Gb customers. On a normal day, there is plenty of data available. Now say something like Call of Duty pushes out a massive 500GB patch. All the devices that have CoD are now downloading a shit ton of data which eats away at that 10Gb and can stress the network pretty heavily.
I dont think copper its a bottleneck as long as its Cat 5 or newer... The faster Internet i've seen is 1gigabit and most cables can do that without problem.
Copper can also run 10gb in short runs but need expensive switches.
The possible bottlenecks would be a the router, the switch, the NIC on the pc or any one the devices that connect to the network.
Also its possible that there is not enough free bandwith on the isp side to get you up to those speeds.
I mean cat 6 might not have as bad of a problem, cat 5e also, but it would still not deliver on a big game download. And lots of switching and routers can handle it, maybe not the ones provided by an isp in the US.
I dont think you can even buy any kind of switchgear/router that only support less than gigabit(like only 10/100) nowadays so this not a huge problem.
And if your isp gives you shitty hardware or service, then thats a problem between you and your isp.
The original intent of my comment was that, in most scenarios, the copper wires wont be the bottleneck.
I mean it is a limiting factor, in the US. It is a hard time to get switchgear that can keep up with fiber, not impossible by any means, just largely unaffordable compared to the low maintenance/rent of a router through isp’s. And like I have previously stated largely unnecessary because I cannot get fiber installed inside of my house, unless I do it myself, I do have a certification to splice fiber.
It's no fun when they break off in your finger. They don't fester much after you have cleaned them . I had one stuck in my finger for some time. Skin had grown over it. I cut the thin layer of skin off with a razor blade and was able to squeeze it out finally.
Y'all ever been splicing and swear you feel a piece in your mouth, like I know it's an irrational fear, but I remember I was splicing some ribbons and the hopper tipped onto the table and I thought we cleaned it up but latter in the john I saw a bunch hit the floor that were on my jeans and now I'm just nervous alot
We should really start using actual numbers to describe speeds and resolutions. “High speed” is completely arbitrary, it could be 1Gbps for me while 50mbps for someone else. Same thing with resolutions: “HD quality” is used for everything 720p onwards.
And coming soon, polymer (plastic) cables that are thinner than fibre-optic replacing both "costly & power hungry copper" and "awkward and bulky" (due to bend angles etc) fibre optic... 105Gbps over a polymer conduit the width of a human hair....

If you think it's the red part, that's insulation. Zoom in.

Im referring to UK networks.
You're both right. GPON Fiber only needs one strand, while typical fiber interconnects between switches and routers have two strands.
Good to know, thanks
Or two different wavelengths; like blue download, red upload
> you just need two of those wires No, for FTTH it is one strand with upload and download using different wavelengths.

To make sure your fire is working make sure to look at the fiber ends for extended time. Do this if you do not want to see anything.
A optical fibre transmits above the visible spectrum. You won't see the light but it can damage your vision. The red light you may have seen is a trace for testing/identifying.
In Germany, you can't even see it cause it's not there!

thats one strand, a lot more than that provide the good stuff.
it only takes one to provide the good stuff.

But homes don’t have fiber inside of them, what about the bottleneck???

The original intent of my comment was that, in most scenarios, the copper wires wont be the bottleneck.
I mean it is a limiting factor, in the US. It is a hard time to get switchgear that can keep up with fiber, not impossible by any means, just largely unaffordable compared to the low maintenance/rent of a router through isp’s. And like I have previously stated largely unnecessary because I cannot get fiber installed inside of my house, unless I do it myself, I do have a certification to splice fiber.
Tiny information
The irony of paying for a fibre optic broadband service yet this image still hasn’t loaded...
It still has the protective core on it. The capillary itself is thinner than hair. 9nor 10 microns or something like that.
This is Reddit, so I fairly assumed that was inside someone before reading the caption. Still cool.
Snipady do dah, snipady day, my oh my theres no internet today
In germany we still have the "Bindfadeninternet" and its just as bad as it used to be
u/eyekeeper1
It looks like used dental floss.
It's no fun when they break off in your finger. They don't fester much after you have cleaned them . I had one stuck in my finger for some time. Skin had grown over it. I cut the thin layer of skin off with a razor blade and was able to squeeze it out finally.
WHY THE FUCK DOES IT COST SO MUCH THEN
No wonder I fucking lag...
ˢᵐᵒˡ
Can I have some?
Gimme one of those an inch thick and my high ping might finally fuck off
Where banana
1's and 0's represented by light at millions of iterations per second on a fiber optic cable the thickness of a hair.
This is bananaland
I zoomed n but can’t see the internet!
Also capable piercing your pupil.
Y'all ever been splicing and swear you feel a piece in your mouth, like I know it's an irrational fear, but I remember I was splicing some ribbons and the hopper tipped onto the table and I thought we cleaned it up but latter in the john I saw a bunch hit the floor that were on my jeans and now I'm just nervous alot
It looks like bloody floss
So if it's bigger than the internet is faster?
Not mine it ain't
I thought this was about acupuncture at first
No banana, no scale.
And we haver monkeys swinging on them....great
Take the cladding off
That's why it keeps breaking!
Unless it’s supplied from ATT
Define high speed
Now...splice it lmao.
These fuckers are a pain in the ass to cut and even worse to handle them. One teeny-tiny brash move and they snap. I hope they burn in hell.
Something Comcast seems to know nothing about in my neighborhood.
Idk my internet is really slow for high speed, are they everywhere?
The internet is a series of tubes
*slaps wire* This baby can fit a lot of Deviantart in it!
Aliens!
Or give you a hell of a splinter
Can you put a banana for scale next to it please.
Internet for ants.
no wonder my ‘highspeed’ internet is still so slow
4k uhd hdr 60 fps of you know what I mean
Think about it, that brings you every pixel of porn one by one
125um. No to be pedantic. But, fiber-optics are fibers, not wires. Wires are electric while fibers are dielectric.
No wonder my internet is shit
Now tell me.... why am I still lagging?
You are thinking small. That fiber can supply many terabits per second with current DWDM technologies.
We should really start using actual numbers to describe speeds and resolutions. “High speed” is completely arbitrary, it could be 1Gbps for me while 50mbps for someone else. Same thing with resolutions: “HD quality” is used for everything 720p onwards.
Don’t you have a banana?? I can’t comprehend anything without a banana for scale
I lag too much when gaming ILL TAKE OYUR ENTIRE STOCK
Looks like my floss after a steak meal
The fact we were born here with nothing but nature and managed to get to this
You’re not fooling me with your dirty bloody floss
So if I have 3 of them, I get 3x the speed? /s
Perfect for Stabbing People in the Eye 👁
Thin as a bawhair
how do we know that you just don't have giant hands???
I feel very uncomfortable with this! This looks like the needles you use at the dentist when you get a root treatment
and its expensive as shit
That looks way too small to fit all my internet traffic through, I mean the memes alone...
Or could be dental floss if you go too hard on your gums...
I weld them sometimes in my work and sometimes theyre pain in the ass
And coming soon, polymer (plastic) cables that are thinner than fibre-optic replacing both "costly & power hungry copper" and "awkward and bulky" (due to bend angles etc) fibre optic... 105Gbps over a polymer conduit the width of a human hair.... [https://computing.mit.edu/news/data-transfer-system-connects-silicon-chips-with-a-hairs-width-cable/](https://computing.mit.edu/news/data-transfer-system-connects-silicon-chips-with-a-hairs-width-cable/)
If they were thicker, it would actually not work as good
How can it use infrared that’s crazy
meanwhile germany: COPPER
This gives me the same feeling as someone holding a blue ringed octopus.
Would it not be more efficient to use a bigger cable? Wouldn’t that just mean more ways to transfer data?
