I work for a telecommunications company that re-sells your products. This was very educational for me, and gave me a greater understanding of how fiber optic cable works! Thank you!!
Single mode - In 2012 Corning recorded max speed of 1.05 Petabit/s over a distance of 52 KM by using a 12 core fiber, check Wikipedia. Multi mode - 16 Gbps SAN switch which uses multi mode fibre is new but the optical fiber is capable of supporting more than 16 Gbps,
If we make a optic fiber that is spiral ..would we get a much denser light for traveling trough optics without bending on curves or getting re fraction (without losing the density of the light and stable traveling trough optics)....
What happens when you have an open in the fiber optic? Even the cladding (or insulator) could cause the signal loss. With Electricity you can repair the connection by splices and sleeves. How would you repair the fiber optic?
wrathoffufuke they do a fusion splice of the individual glass fibers when the cable is cut into or the cable has been damaged, just like with copper you can splice the glass back together
You can easily splice optic fibers with an automated fusion splicer. There are some simple ones for less than $1K, and some that will splice multiple fibers at once.
copper lot easier..just used crimper and cutter..just get cleaner copper and rg6 adapters...plus barels are cheaper..anyone can fix copper coaxial cables easier than trying to fix fiber yourselves...?? costly for repairs and costly do it yourself...satellites sitll wins for do it yoursleves with all the tools alvaible at home depot
when it's a matter of speed, copper can't cope with fiber... you can move up to 1.4TB of data with one fiber, but you'll need hundreds (if not thousands) of copper cables to reach that speed... now tell me how much man hour cost to splice that amount of coper cables against 40 seconds of automated fiber splice? yes, the equipment cost 1k but paying a group of workers to patch a thousand cables could cost even more
My question is if you have a long stretch of fiber and it is broken/cut at a certain point. Is there a way to join the two seperated ends of the fiber? Or does the entire line need to be replaced?
Yes, you can splice the broken cable back together. You don't need to replace the entire line. Two ways to do it is a mechanical splice or fusion splicing.
@@randysansom3328Yes, though the fusion point later isn't as durable as the rest of the cable (has higher risk to be broken again). With proper installation, no need to worry about that. From my experience with fiber optic, most of the time the fusion point broken again was due to poor installation after fusion or the customer moving the cable on their own.
This is how IP UtiliNET delivers Internet Extension Cords. Dedicated Private Fiber Optical Service Networks at up to 20 Gb over single strand, single mode fiber up to 80km away from Internet cross connects. Like IP UtiliNET, Like Corning
so since optical cable is everywhere if someone where to cut a section of it how much of it would have to be replaced can it be cut and melted together or would it have to be replaced to the next repeater?
After so many years of hearing and reading about optical fiber and FTTH I finally have optical fiber carrying internet to my home. Yaay!! India, 2019 AD
If the fiber is damaged (crack in the glass, or breakage etc.) at a distance, is it possible to pinpoint, where the damage is along the line, or is the entire line replaced? How is this done?
Draco Safarius Basically, you use a tool that measures the intensity of reflected light at source and the time for the light to be reflected to determine the distance to the break.
All about the money dude. Company's almost always go with the "cheaper" option to make customers pay enormous amounts for high speeds on that type of connection when realistically you could get speeds far beyond that for cheap. But they just loooove large profits
I know, right? In reality, though, it's well-known that the fiber cabling has its own unique set of limitations - some of which are related to the extreme challenges of splicing, signal tracing, and signal division (3db splitting for example). Draco Safarius correctly assessed the profit motivations, I think. But also, it's really overkill to interface optics to a residence when low-loss coax is available to use from the optical node at the street to the home I suppose. I'm still trying to figure out how my the coax cable gets "shovel rash" about once a year !
The speed is 3.28 x 10(28)m/second there is no loss or attenuation. They are more secure as loss can be detected. SM is 9 microns used to connect two sources together over a long distsnce and MM is 50 microns used in shorter distances, generally inside a buiding is my understanding
Um, Fiber has been used widely for over 40 years. Everything is already transmitted over fiber, even if you have Coax or Twisted Pair in your house, there is still a fiber network upstream of you. Fiber is very expensive to install compared to copper.
@@mikel9567 I don't agree fiber, can be made by plastic recycled plastic this with 6H2O en that is waterstofdioxide In The Netherlandswe collect this for now several years Yeah we are working for a more clean and lifeable world, no pollution at all, thanks and kind regards.
@@mikel9567 Dear Mike L I like to ask you why fibre is so expensive, it's made out of recycled plastic in the Netherlands. Is there still cupperwire under the groud up there, That is also a possibilty, Thanks and Kind Regards.
U dont focus about the important physical phenomena that some spectrum of light came to receiver later due to reflection on edges of the fiber optical .
Hi, sorry I have this thing at home and for what use this thing, I have new one package, what I must do with this? Can you help me? And what name of this thing? Thank you
it really isnt that fragile. cost to fix it - depends on how the network is built, and where the damage is. where the possibility of a damage is high, it is usually not long lengths of cables. And fiber cables are usually put into pipes, so you just drag it out and shoot a new one in, splice it up and done.
In eastern-europe, bigger cities have 1Gbps fiber optics internet for like 15-20 bucks a month. Its not that expensive, tho deploying it has a high cost in high income countries i guess.
Bring back coaxial cable!!! :P We have fibre cables in service today that were installed in 1984. They are carrying 10Gb/sec services between substation pilot systems - as well as corporate comms. One circuit is 120Km long. All still going well.
Shouldn't it be called Index of Reflection, because the description at the 3:00 mark first says the light travels from one medium to the next and changes speeds (IOR), then it goes on to say the light is trapped in the core. How can it be possible that the light is trapped in the core at the core/clad interface, when the mode field diameter @1310um is different than the MFD @1550um? The light cannot be both reflected and refracted at the same time. The term "Total Internal Reflection" is wrong. It should be "Total Internal Refraction". There's no reflection taking place. In a graded index MMF, some modes never even make it to the core/clad interface.
I really hope this gets to my area soon, as the wifi is usually at about 100 kilobytes/second (though I am watching this on my pc, which is directly connected to a cable at about 3.6 download and 0.79 upload).
Why does it seem it’s been so slow to adopt, I’ve been waiting ever since we were supposedly “able to hear a pin drop” when MCI started marketing in the early eighties.
Because most companies use far lower grade copper based cabling in-homes and/or limit the speeds to houses severely to make people pay higher amounts for higher speed. All based on them getting large amounts of profit for cheap amount of investment. Theoretically you could lay out fiber to homes and into, sell it at a reasonable price for high speeds, and rake in the money; but companies will stave that off as long as they can. Little sidenote to it though, why I'm hoping most countries end up like Finland (i think it's Finland lol) where they declare high speed Internet access a human right along with stuff like food and water. Means most every house in the country would be required to have some form of incredible connective speed
2 billion km of 8 um single mode would only be 100 cubic meters. Amazing that one number is huge and goes astronomical distances, but the actual volume of it, well it wouldn't even take up 1/5 of an average-sized home's volume. Tells how thin it really is.
its not the affordability of it in my area, the elderly in my area have this preconceived notion that the internet is useless garbage while cable tv isn't and this area is majority elderly so we can't get it in cause they won't allow for it
@@jmbrady1 So what? Older DOCSIS 3.0 can achieve 1 gigabit over cable. Symmetrical DOCSIS 3.1 can do 10 gigabit upstream and downstream over cable. Why did I NEED fibre??
Actually, it's more than 1 Gb/s. But since Google Fiber is used for more than just Internet bandwidth, but video too, the real bandwidth is more like 5Gb/s - possibly higher.
The illustration and explanation for the propagation of light in single-mode fiber is wrong. The cut-off wavelength is also misinterpreted. Strangely, Corning has been making fibers for more than 40 years, strange is why no specialist has consulted it. As an animation, the movie is otherwise nice :-)
Well, fibers been around for a long time, google is just getting tired of these slow ass internet carriers in the US not updating their last mile networks, so their doing something about it where it make's sense.
Yeah but they get stalled out by larger monopoly based areas, which I guess is technically illegal to have a monopoly, but it all gets tied up in larger bullshit. Why Google Fiber is so slow going, every Internet company that's sizable tries to stall it out to maintain their monopolized income. Also yes, I am replying four years late LMAO
It's not true that Fiber Optic cables is strong!!! I broke my Fiber Optic cable on my router that's why I watched this. The material used for currently commercialized fibers (core and cladding) include pure glass plastic, or a combination of both. Fiber Optic cables are sensitive as fuck, just one small bend and your Internet connection is gone.

Thnak you! This lecture is really informative!
Do we also know what we will get at the output of a SM fiber for an incoherent light input?

Excellent presentation ...superb 10/10
How are fibers connected to each other when repairing or extending a part?
By means of fusion splicing
Ductape
Yeah, fusion splicing is used and usually to protect the fusion a specific kind of heat is used so that the exposed fiber doesn't break.
If we make a optic fiber that is spiral ..would we get a much denser light for traveling trough optics without bending on curves or getting re fraction (without losing the density of the light and stable traveling trough optics)....

Draco Safarius Basically, you use a tool that measures the intensity of reflected light at source and the time for the light to be reflected to determine the distance to the break.
That's cool as shit
You use an Optical Time Domain Reflectometer that measures distance on an optical fiber then it can be re fused for repair.
This is my new interest. I want to master it.
And yet we STILL have phone lines or coax coming into our homes...

and jump ot fast speed energy it should be able right?
Is there glass or space in the part we call core in multi mod or single mod fiber?

One problem: can you rewire cut fiber optic with duck tape?
that cause u dont add electromagnetism it wave band curve ..this is laser focus
warts, transmit light? like a fiber optic cable.
Stronger than steel! Try pulling a single strand of fiber sometime between both hands to break it. Good Luck!
motormovies76 it's easy to break. It's thin glass. Or do you mean the whole fiber shielding and insulation? There's Kevlar in it.
I mean it gets damaged, so imo it's better if it just dies right away than sending me like 2/5 the internet speed.
So that’s what fiber optics is(confused look on face pretending to have understood the whole video)
Bad bad bad bad bad bad bad bad bad!
Is it fragile? What if it breaks, what’s the cost to fix it?
