Fiber optic cable: Multimode vs Single-mode

Today my topic is fiber-optic cable. Specifically, I will talk about the structure of fiber cable, single mode fiber, multimode fiber, and their major differences. I will also compare the fiber-optic with twisted pair in terms of benefits and drawbacks.

You're the man Sunny, I enjoy your classroom ! thank you, I hope all is well and you're safe.

[@mackbolan3707]

This video along with the other about the media converter was very helpful to me. Thanks so much for taking the time and effort to make it.

Thank you so much sir for the informational video. The covid reference and the tip on washing hands was grat as well!

[@MusicAInz]

I am going to take Net+ next week and I was really worried if they asked me 'What duration of time should you wash your hands to avoid COVID?" on the test. Now I know and I feel a lot less anxious. Thanks Sunny Classroom!

[@JosephCompian]

I wish I would have found you earlier, the use of pictures and bullet points is great for my style of learning.

[@robmcgowan4055]

I think I have watched all of your videos now. Thanks, Sunny! You speak well and I enjoy your occasional jokes. :) I like your animations too. They are very helpful. Do you mind if I ask what tool you use for your animations?

謝謝。I should warning to SMF or MMF compatibility with my sfp+ network card?

[@ednakanawila5527]

Sonny is a good teacher

[@Nerino]

Well explained. I have a question, I'm living in prefab building and Fiber is available there. Can it run to the switch somewhere so I can use my UTP cable as I have it now to my router which matches the speed? Am I able to do it by myself without a technician entering my flat?

[@alroyshaw1054]

Yes you can however you would need two fibre converters for youre network.

[@DelsonFilho01]

Very good resume!

[@sunnyclassroom24]

thanks.

[@mcw1593]

I was listening to details on multi-mode fiber and then got a hand washing lesson. LOL

[@Miliykot2013]

Thanks a lot, just question there is a compound gel leakage from SM FO cable installed, what is the reason? and how it may impact to SM FO cable functionality?

[@vivekprajapati4787]

[@psbitadmin213]

Just in the right time sunny

[@sunnyclassroom24]

Thank you for supporting! stay safe!

[@djordjeblaga7815]

I have to say in practice basically no one uses Multimode anymore. Singlemode has become pretty cheap and with WDM you can transfer a lot of channels over the same fiber at speeds of up to 100Gbit/s. So even if you've got a 100m run between two buildings I'm still using singlemode cable.

[@catfishrob1]

I would say that's largely true, however, the LR xcvrs are still multiple times more expensive than SRs, and that can easily add up over hundreds of connections. Not only that, but if you use LRs at very short distances, because of the higher power, the xcvrs can burn each other out. In other words, they have to be replaced more often. Sometimes for simplicity (not having to stock MMF equipment) companies will elect to go pure SMF (or close to it), but this is not without its (primarily financial) drawbacks.

[@ElreyRayo]

Gracias! very useful

[@sunnyclassroom24]

Thanks!

[@pootitan3000]

Hi Sunny, thanks for the excellent explanation! Could you recommend some books to introduce how the internet works in the whole picture?

[@m3hdim3hdi]

computer networking a top-down approach

[@footballhighlight2350]

Happy birthday to you Sunny :p

[@El650Jefe]

So mode just means a different path right and has nothing to do with wavelength? So for example if I have a single mode fiber and have rays of different wavelengths all traveling along a straight path down the fiber. Because the only path is a straight line and even though there’s multiple wavelengths of light, we still just have one mode correct? Now if I have rays of different wavelengths or all of the same wavelength but are traveling along the fiber at different paths I have multiple modes. It’s the different paths which makes this a multi mode case not the the fact that there rays of different wavelengths right?

[@vnetpost]

thanks sunny

[@sunnyclassroom24]

welcome

[@zaouibrahim8668]

how to study the transmission of a single mode optical fiber SMF by optisystem ?

Hi there , you didnt mention how much is maxium speed & distance support on Multimode Single-mode ? thnx

Can u make a video for the people who are new into networking world ( students ) in general and give some tips it'd be very helpful for many

[@sunnyclassroom24]

will do! Many thanks for your trust in me :)

[@amineachoura9350]

Hello i have a question about symmetric key , i saw your video and u said we use private key but i found in other videos that we use public key , is that right or no ?

[@sunnyclassroom24]

A symmetric key is a private key in private encryption. The public key encryption uses Public key and private, but public key and private key are inseparable twins.

[@Arganoid]

When you connect to a secure website, public key (asymmetric) encryption is used to initiate the connection. This encryption is used to send a private key. Then symmetric encryption can be used from that point onwards.

[@teroblepuns]

Coax over Docsis 3.1 can transfer download speeds of 10 GBit and upload speeds of 1 GBit. How does fiber compare to that?

[@samiolmari3821]

Everything else was very well laid out, but _why_ would multimode be better for short distances? Modern day the stuff costs is practically same, so going for multimode does not give you any benefit... Only if you already have multimode infrastructure and need to expand it, multimode makes sense now.

[@GaneshJayaraman]

was listening until you mentioned covid...that shit done exist dawg. and viruses aint contagious either.

[@cokeforever]

being an IT professional, you should be more accurate with terms and acronyms: the virus is correctly called SARS-nCOV-2 (severe acute respiratory syndrome causing novel coronavirus type two) and the disease it is causing is dubbed COVID-19 (COronaVIrus Disease first reported in 2019).

[@sunnyclassroom24]

Thank you for correcting me. being honors to get comments from you.

[@ovidiunaso5639]

negative for involving covid with fiber optic.
