fiber optic cables (what you NEED to know) // FREE CCNA // EP 13

Splicing Fibre is nothing special and it's very easy if you have the equipment. I used to be a field engineer working on the backbone of the network and the equipment inside the street cabinets and my salary was like £33K. I am now a technician in an Equinix Data Center.

i had it with verion greatest ever was faster then cable tv my web browser and downloading huge games was childs play

Thanks Chuck👍

Thank you for this video NetworkChuck.

I know im late to the video but i did want to say a little on making your own fiber cables. Yes, splicing fiber requires a specialized fusing machine and its something the average guy wont do. However, its very possible to put terminal ends on fiber. The kits are usually under a 100 dollars and once you get the hang of it you can make up a termination in about 5 minutes. Its a bit of a learning curve but its a alternative to buying all premade cables.

Lets go

Great video, but they don't just use repeaters to help the signal go further, they also use the much more efficient method of amplifiers, which are pretty cool.

I will be passing this video to our new Technicians. I have been doing Telecommunications for 24years now. Some of the information is more basic and general. But working in the data center capital of the world. I have stories to tell. But I started a Tech right out of high school. When I started most customers fiber circuits were 155Mbs (OC3), and 622Mbs (OC12). Now I install 10G, 100G, and 400G. The need for bandwidth has grown in the 24years. Also the more commonly use BIF (Bend Insensitive Fibers) reduces the micro bends.

Sorry to ramble but good video and I know I know a lot of the technical spec.

Also never look in the end of a fiber is a laser and will burn your eyes. Always use a light meter to measure the db levels.

man .. i feel like doing a CCNP recertification after watching your videos .. just for watching your video lectures Lolz 🙂

I thought fiber optic cables are normal

You always have such incredible and informative videos!!! Thank you so much!!!

❤

Bro just unplugged his fiber cable and plugged it back in without cleaning it.💀💀💀

You mean total internal reflection

What is a good fiber modem or just use the ISP gateway?

Lc to sfp

I'm not an expert, i just started using fiber inside my home.
It looks like it's pretty easy and cheap to terminate and splice fiber with less than $100 from Amazon tools (could splicing). You need fiber strippers, cleaver and fast connectors or cold splices.
For lower attenuation (likely not relevant at home) you do fusion splicing and that's more expensive because the tool costs around $1k.

Experts: please correct me if I'm wrong

i live in germany i just got upgradet from 3 mbps to 25mpbs and i only have to pay 35€ a month xD

I splice fiber for a living just did a 72 strand fiber need special equipment and testers to do it

Cool to see that cooper is not longer cheaper than fiber :)

I managed to terminate 9/125 singlemode fiber cables, with fan out kits and a Chinese cleaver (under $100), even with 60 yr old eyes. Reason was, broadband was not available to my rural home but an adjacent property had it, so I trenched and buried 2000 ft of jacketed fiber to carry the gig speed internet LAN to house.

Pretty sure cisco will be adding MPO soon to CCNA for fiber. Might also go over MLOM cards. Unless you do that later.

i cant make my own fiber cables?

HI MASTER
LOVE YOUR PERSONALITY AND WAY OF TEACHING.
YOUR DAUGHTERS ARE REALLY CUTE.I PRAY FOR THEIR BEST AND HAPPY FUTURE LOVE THE WAY YOU TREAT YOUR GIRLS TOTALLY AWESOME.

VERY POLITELY PLEASE UPDATE

ITS TOTAL INTERNAL REFLECTION.......AFTER A CERTAIN ANGLE REFRACTION IS TOTALLY REFLECTED.

Is this that guy that sips on his coffee like it's a cancer diagnosis?

@NetworkChuck I am just installing and learning about fiber optic cables and another important topic concerning LC cables ar the verions of LC cables. There are LC/PC, LC/UPC and LC/APC which are not necessarily interchangeable. LC/PC is 90° connection LC/UPC seems to be polished more for better attenuation. LC/APC here the connection is done over an angled cut fiber optic. If you put a LC/APC into a port that should have LC/UPC or LC/PC you will get a huge attenuation and will only get a fraction (4%) of your throughput. That is the problem I am having with my provider at the moment. I put the wrong cable and instead of 25Gbit Internet I get about 1-2Gbit.

thank you so much, im competing in skills nationals and need to know this stuff in 3 weeks

hello bro i like your video. i would like to correct you where you said total internal refraction. this is not refraction this is reflection.. a big difference

You have a beautiful family!

Awesome video. I am a fiber optic splicer/tester for a company in NYC. I am the supervisor for the department and we are contracted by Verizon and Altice to build there backbone networks underground in the Manhattan. I love to see videos explaining the tools and resources we use on a daily basis. I love your channel. I have tried some of the projects (running my own AI bot with Ollama through Docker for my kids to use when they need help with their homework) and learn much about other things watching your channel. Keep up the amazing work.

Just found your channel. Your a fucking rockstar, mate. I have liked, subscribed and activated notification. I've already binged away half my day on your top shelf content and looking forward to watching more soon. I hope this comment finds you and your family healthy, happy, and thriving. Cheers! ☘🎨🤘

Its worth mentioning, if it hasn't been mentioned, that you should never look directly into the end of an energized fiberoptic cable. The light used in telecommunications is invisible so you wouldn't see anything anyway and it could potentially cause retina damage. It seems it would be human nature to look for the light if something might not be working for some reason.

glad you apologized to Ethernet cable

Actually It's not speed of light. It's the super wide bandwidth of electromagnetic wave.

A question. What would be if provider provides fiber to my router, but then it goes to switch via ethernet cable - will it loose speed to end users from switch? Or if modem is conencted directly to pc via ethernet, again it should loose speed? In order not to loose it, fiber should be used from provider directly to pc? But what if fiber is connected to wifi router, will it give more speed for wifi users?

It's total internal reflaction

I am a fiber technician, and make these fiber connector almost every other day. and it's not that difficult to make them, with right tools you can make them in minutes. Yes, those tools are expensive though, one will not get on amazon. Also, SFP are also called ONT (optical network terminal), converting signal from optical to electrical. Your course is amazing, learned lots of new things about network. Thank you so much for that.

yes aqua

thanks chuck... you combined with messer is gold

You are confusing fiber cable a layer 1 tech with ethernet layer 2 protocom, both copper and fiber can carrie ethernet packets.

Fiber cables are used because they are cheap, but microwave links are actual faster than fiber cables.

Also, you may have to split the fibre connectors apart to re-arrange them accordingly to the arrows on the transceivers.

I've seen an employee splicing a fiber cable in front of me, it's not that hard, but it needs skill and proper equipment.

Electricity travels as fast as light. The advantage of optical is bandwidth. It the frequency that allows so much data to travel in optical fiber. Optical computers are under development.
