First year of my computer science degree we learnt about logic gates. That's literally redstone. Fun experiment for you, go on minecraft and make a NAND gate. This is a gate which has 2 inputs and 1 output. The output should always be ON unless BOTH of the inputs are on in which case the output should be off. The cool thing about NAND gates is that you can use them to make all other logic gates. Try to make the following gates out of just NAND gates (either building them manually or copy and paste using worldedit): NOT - 1 input signal, output is on when input is off and off when input is on AND - 2 inputs, output is only on when both inputs are on OR - 2 inputs, output is on when either of the inputs are on XOR - 2 inputs, output is on when either of the inputs are on BUT off if both inputs are on You can keep building these up to create memory chips, processors and then a fully functioning computer! If you want to look further into it (outside of minecraft) then take a look a the website called nandtotetris.

I used to work on fiber optic equipment (wrote the software, but still had to know a good amount about the hardware). The way light carries data can be much more complicated than just flipping the light on and off. The transponder I worked on used 16QAM modulation sending the data in a combination of the amplitude and phase of the light, allowing for 4 bit symbols (any one reading from the fiber provides 4 bits). We transmitted at 200 gigabits per second (per slot within the ROADM network).

@@ulpnationll2953 There are so many things to cover with what you're saying that I have neither the time nor the crayons to explain it. Efficient fibers, called Ultra Low Loss Fibers, have 0.15 dB/km of loss only for one specific wavelength because of their core size compared to their cladding size (9um/125um) and because of the difference of refractive angle between the two. If you don't couple light properly into the fiber, you get more losses because of total internal reflection, yes. Same if you bend the fiber too much. Fibers work because of the difference in refractive index between the core and cladding. Fibers that work efficiently don't use visible light.

I am a IT consultants that became a network and fiber optic engineer and have been in the trade for many moons. Linus you should have mentioned the difference between single mode and multimode as their limitations are different. This is a very entertaining way to explain how light travels through a fiber but not necessarily how data travels or how its converted to light, we missed packets, frames, and labels, you also forgot to mention the vacuum in the fiber strands which allows for light to travel further. Nothing on attenuation or operation at 1310nm or 1550nm. Next you glanced over wavelengths possibly due to time but Wave division multiplexing that grew into DWDM and its advances to go from 1Gbps and 10Gbps to 40, 100, 400Gbps are the reason global bandwidth has grown. Then 0 layer switching, it is what allows for light to be switched on demand without physical intervention. You could spend half an hour on that alone, Dont even start on ROADM's LOL. Also the chemical reaction discussed in helping light travel further only works with certain types of fiber strands, the rest need a physical regeneration point closer, converting light to electrical then back to light again, about every 80 or so kilometers. The physics of light energy at the output level disburses or degrades at this length, even in a vacuum or in a perfect reflective environment. So all major telecoms depending on the type of fiber whether Corning Leaf 0 dispersion have to plan their repeaters carefully. You never mentioned ITU standards like G.651 or 652. Again possibly due to time. It's actually a hodgepodge of network cable out there all working differently at different lengths of regeneration points. The advances in Switches and Routers has allowed for full use of these hodgepodge networks. By the way I have been a loyal fan for years now, and this subject should not be a tech quickie but I will say this was an admirable go at it, and a very good explanation. I know veterans in the field that could not explain it to a customer as simple and as graceful as you did. As I recently became a KZread creater I know how hard this is.

By the way, multimode is used in metro areas to tie buildings together so while it makes no sense as a interstate communications medium, it is used many times in dark fiber loops that connect buildings like hospitals together. Not my suggested way but it is the cheapest. MM does achieve great distances when compared to copper. So by skipping it I think the tech quickie lacked. Linus is not a network WAN engineer yet I complimented him on his effort and even told him that many veterans could not done as well.

Multiple light waves can be sent through one fiber and at amplification points the light gets separated into the individual waves amplified beyond the necessary strength then subsequently reduced in strength to a more precise signal strength at which point the individual waves are then re combined or multiplexed and sent back through the fiber on the other side.... some of these systems are fully reversible others are directional depending on its function.... this gives us the capability of pushing over 400gb/s over a single fiber run

0:23 Linus hologram shaking.

This is a great basic explanation. There are a few inaccuracies, however that could be corrected without making this explanation longer or more complex. Modern optical fibre does not make use of total internal reflection - we could never really go much further than a couple of kilometres if that was still the case. It actually uses a refractive index gradient (as opposed to a hard boundary) to guide the light back into the fiber. Check out the difference between step index fibre and graded index fiber. Repeaters vs amplifiers. Hmmm…to be honest these two terms are interchangeable, but they both just mean “amplifiers”, and more specifically “optical amplifiers” (like EDFAs, SOAs or Raman amps). You may have meant to compare amplifiers to regenerators - which digitally recreate the signal, as opposed to an analogue amplifier. Regenerating signals is expensive compared to just amplifying them, so the goal in modern long distance communication is to send the signal at the highest possible data rate as far as you can before you have to resort to regeneration. But you may still amplify that signal about every 50-80 km. Just to note that optical fiber was used in endoscopy way before it was used in communications, at least in terms of commercial products. Endoscopy dates back to the mid 1800s using hollow tubes, but fiber endoscopy was invented in 1957. The use of fiber for communications was triggered in 1970 when two technologies reached a sufficient state of usefulness that commercial products could be created. These two technologies were low loss optical fibre and semiconductor lasers.

This is true but not the full story about fiber optic networks, nowadays to use every space there is inside the fiber, multiple carrier frequencies are used (different colors). This is then multiplexed together and demultiplex at the end which is often done with a simple n-th order filter, giving the individual 1's and 0's back for each wavelength.

@NATAWS9

2 жыл бұрын

Fiber advantage is distance of transmission, not latency. Latency only becomes a problem when repeaters get involved and this is required when signal level degrades, which is faster in copper. For short distances, this isn't a problem. Also, HDMI has more on it than just digital signals. It also has auxillary power which cannot be transmitted over fiber. Audio systems use electrical signals that are amplified by speaker amplifiers. Before the amplifier, optical cables are possible but don't provide any benefit. After the amplifier, optical cables are not possible because they would lose all of the wattage needed to power the speakers.

I remember when I was a kid in early 80s, I shined a flashlight through a metal tubing. I've noticed the light would seem to bounce off the reflective walls in the tube making the light shine bright to the other side. I was thinking maybe I could use this to connect between two places with long piping and use it for instant Morse code without using radio. I was a smart kid back in the day. I don't know what happened lol

I worked in this field with EDFAs before the telecom bust. Each fiber in a 40km link could handle 80Gb/s through muxing different wavelengths of light onto the single fiber. We developed 32 ch systems that had EDFAs(erbium doped fiber amplifier) which used a 970nm laser pump to amplify the optical data stream, in phase, by 16dB. The technology was pretty amazing even for an EE like me.

I studied telecommunications and the physics behind it, but I can't just say no to a new video by Linus

i always like linus's vids for his Ad transition

Great, now can you explain why I've been waiting for 5 months to have my fiber installed to my house?

When you are early but the video is loaded

The transition to the sponsored message was smooth AF.

Every question was answered as I was about to ask. I like your teaching style. Keep it up! Not sure if you talked about this though. What is the minimum distance a signal needs amplification? Thx.

the minimum distance would depend on the refractive index of the material being used. If you have a higher quality material, the distance required before amplification would be further, a fiber with a worse refractive index would scatter sooner and require a repeater/amplifier in a shorter distance.

It's like RGB lighting, but really, really fast.

God said, let there be light Then there was light and all was well with the gamers

with no lag. amén

your explanation for the repeater was good but you didn't tell how a regenerator works using the dcc channel ? and what transport equipment is being used (ocn) the distance is not determined by the fiber but by card in the transport equipment (ocn). what type of fiber are using single mode or multi mode?

Also useful in offices or even at home... No need to worry about separating internet cables from power lines and extension cords, using more expensive shielded network cables... is very future-proof and thinner

In future I believe UV-Ray and X-rays could also carry data

UV probably but Xrays can't currently be sent through fibers like visible light can. Although, yes, they could transmit far more data than visible or IR (which is more common right now)

UV scatters alot so it's impractical ..and x-ray..nope! Unless you want cancer . . . Although UV also causes cancer

Dr. Linus, PHD MD if you could only be my college teacher, I would have finished my ECE course and never switched to something else.

Please make a video on how Water could be used to store data. There is enormous research going into this.

I thought you will say, "I know where the doctor got his degree,..... 'BRILLIANT.ORG'"

Watching this again in nearly 2022. Forgot what Linus looked before COVID-19.

Just scheduled a colonoscopy yesterday. Thanks for lightening the mood/slash making me think about it again, Linus.
