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,
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 !
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
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.
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
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
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.
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.
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)....
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.
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??
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?
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.
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 .
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.
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
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
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.
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
