Fiber Optic Basics for Field Techs

[@crossdimension4031]

LC = little clip, SC = square clip, ST = Turn because you have to turn the connector to fasten it. That's how I remember them.

[@HenrycSchlangen]

Little connector, stick and click, stick and twist. That is how i was taught. Just wanted to share.

[@Errcyco]

ST feel the best to me.

[@michaelbauerle9182]

ST secure twist

[@noelzacharias1937]

Thank you very much. This video was very informative.

[@ctsnctechnologychannel6342]

This is really great for anyone that wants to deal with Fiber Optics.

[@SumitKumar-ic8yj]

Thanks for your help sir love from india

[@Errcyco]

ST connectors are the best looking and feeling. I remember back in school though before I got my certifications they had us work with this very old, German style connection and it was neat.

[@NetworkAdvisor]

Interesting Mark. Thanks for adding to the conversation. I'm no fibre expert. Just a telecom tech who runs into this stuff on a occasion.😄

[@Hamarachannel007]

great explanation....

[@andrewpndavies]

Great video - can’t like it enough!

[@NetworkAdvisor]

Thanks for the glowing feedback, Andrew! 😁

[@Kevedo61]

Great and easy explanation ! Thank youuu

[@NetworkAdvisor]

Glad it was helpful! :-)

[@ITandAutomationAcademy]

Thats so nice and sweet

[@mariamfirdous8456]

this is very good , quick and precise. ty for sharing.

[@NetworkAdvisor]

thank you! that is my goal. Keep it short and simple.

[@CC-zr6fp]

I always remembered them as LC =Little Clip, SC = Stick and Click, ST = Stick and Turn

[@NetworkAdvisor]

Ha! I love that! Thanks for sharing that tip! 😄👍

[@pratiknilugal]

Thanks, Very Useful Information..

[@NetworkAdvisor]

Thanks for the feedback, Pratik. And, thanks for watching! :)

[@characterK]

Also, yellow jacket pigtails are single-mode fiber. Orange, blue, slate, and green are different size diameters of multimode fiber.

[@NetworkAdvisor]

That's really interesting Kyle. Sounds like you know a bit on this topic. Are you a fiber guy? I wish I had a multi-strand fiber cable and a breakout box I could have demoed in this video too. I am not a fibre installer so much as I just end up running into it a lot when cross-connecting switches to IDF rooms. Thanks for sharing the info -helps us all out. 😄

[@characterK]

I'm an outside plant fiber splicer (the guy in the bucket truck and splicing trailer) for an isp. I also do some work in headends. I love your videos.

[@NetworkAdvisor]

Wow, Kyle. Honored to have you. Thanks for your contributions. I would love to spend ten mins inside one of those trailers just to watch over your shoulder. 😀

[@xavtek]

There is one thing I do not get yet : why does certain connections need 2 fibers (Rx/tx) and others only 1 fiber ? Does light go though a fiber in both ways at the same time or the transceiver needs to wait to end receiving before sending ? I bet there is some multiplexing involved and transmissions on different wavelengths but I didn’t find a proper/simple explanation yet. Thanks !

[@characterK]

I've actually been thinking of starting a youtube channel of my fiber optic journey out in the field.

[@GTVAlfaMan]

LC and SC are the most widely used connectors today.

[@NetworkAdvisor]

Ah, good point. Now that you mention it, I guess I haven't seen any ST in a while. Thanks for contributing. ☺️

[@MichaelStepniewski]

@@NetworkAdvisor I usually see ST used in SCADA or OT implementations of fiber. Also, I've noticed that there are the APC used in OT more often with the green angle-cut ends where the blue UPC in IT with the flat-cut ends.

[@Optimisst]

Thank you

[@pablosalfate7614]

greate video, thanks

[@NetworkAdvisor]

Thank you for watching 😊

[@ikkuranus]

The transceivers don't always use a laser. Multimode often uses LED since it doesn't have to go as far.

[@NetworkAdvisor]

That's good to know. Thank you for adding. I'm certainly no Fiber Optics expert. I'm just sharing my practical field knowledge form installs I've done in the past. :-)

[@peteradams7457]

Jumpers with an orange jacket is multi mode and yellow single mode. We still have d4 and biconic in the company I work for as sad as that is. Also have lc,sc,apc-sc as well though do moving up in the world

[@likeapro6896]

Very good!! Thank you very much.

[@NetworkAdvisor]

Glad you liked it! :-)

[@chandnimahajan2791]

Thanks for sharing this

[@ristanadwicahya]

Hi, may i ask about signal attenuation? If i use a single mode fiber optic that design for long distance connection (lets say 40 kilometers) into a shorter range connection (500 meters) is it can cause signal attenuation? Becauss the laser beam is too bright in the receiver side?

[@NetworkAdvisor]

These things you mention I believe are referred to as Budget. Unfortunately, I am not qualified to offer much guidance on the topic of budgeting, but shouldn’t be too hard to find online

[@ristanadwicahya]

@@NetworkAdvisor no, I'm just curious about this topic, i watched linus tech tips before and he mentioned that if the light or laser beam on the destination side is too bright, it can cause signal attenuation, but i forgot which video and which part of the video he say that.

[@TheMcTimzo]

Great video. I think it's not that big of a deal if you accidentaly look into a multi cable/trasceiver, since (as far as I know) they mostly use LEDs. On the other hand, single comms use laser as a source of light wich is way worse for the eyes.. but yea, dont look into fiber transceivers and cables

[@NetworkAdvisor]

Agreed Timotej. I appreciate your input. Thanks for watching! 😊

[@xavtek]

It might not be painful but I was told that some transceivers emit laser light close to the UV wavelength. And it is definitely bad for your eyes as it destroys parts of your light sensitive cells, without you immediately knowing.

[@NetworkAdvisor]

Good to know. I have to research transceiver power budgets next, so I might learn more about that soon.

[@Davysprocket213]

Is a transceiver and a media converter, the same thing?

[@NetworkAdvisor]

Thats a good question and I’m not sure. I apologize if I was using those two terms interchangeably on that video.

[@Ressy66]

1, always asume a fibre is lit 2, the light is the infra-red range, invisible to naked eye,m the danger here is, when your eye see's something nasty, it makes you close/squint so the risk of damage is unlikely, just as if your in dark room and shine a torch light towards you - you look away, same principle. However with infrared light, there's nothing for your eye/brain connection to alert you or go ' oh crap and close up/turn away from, hence starring at it can be risky despite its generally low power, the chances of damage are small, but play it safe never look into an end, at any time. Those who have gone blind have been the ones foolish enough to use a magnification device staring down it. If you want to see if your fibre is producing light, use your mobiles camera - unlike human eye, camera does detect IR bands.

[@NetworkAdvisor]

Interesting stuff. And, good to know. Thanks for sharing. You may have saved someone's eye-sight! :-o

[@MCrystalMaidenn]

how does the glass in fiber optic cables bend

[@NetworkAdvisor]

I know… seems weird. The magic of Corning Glass.

[@abdullahelnaggar5467]

Hi, i have some questions regarding the fiber optic, i hope you have answers for them 1-What component does a BH Fiber connect to? Switch-Digital Unit-Microwave-Router 2-What are common sector names? Alpha-Beta-Echo-Gamma 3-What type of cable is used to connect to a copper SFP? Ethernet-Coaxial-Fiber-Stranded

[@NetworkAdvisor]

hi Abdullah. Thanks for watching my vide. Unfortunately, I'm not the person to help you with those questions. Fiber is not something I do a lot of, I just made this video to share the basics.

[@drunkmadala]

Thanks, very interesting video.

[@NetworkAdvisor]

Thanks watching and leaving feedback! 😁

[@marcooconnor]

You also get SC-A cables etc which confuses it a little more

[@NetworkAdvisor]

🤦🏻. Hahaha. Well good to know then. 😊

[@xavtek]

Nice !!! Could you get into the details about optical câble strength ? I had several offices installed with fiber optics and some of the guys told me that fibers cannot make more than a 90° turn. But from what I understood browsing and searching, câbles now are really tough and can stand a lot of bad situations. Do you have any experience about this ? Next step : splicing your own fiber connectors. I have seen several technicians do it and with the proper equipment, it does not look that hard :)

[@NetworkAdvisor]

Xavtek, thaose are all great questions. Remember, or in case you didn't hear it, at the beginning of the video I said I was not a fiber expert. But, I will see what I can do since I want to know the answers to those questions too. As for the 90 turn idea, I know that I have put in many short multi-mode patch cables where they were turned 180 degree. But, I do know the fiber cables can't make sharp turns. The turn radius has to be wide. Great questions and thanks for watching. 🙂

[@jaimegpppz3552]

good afternoon where can i buy that product Thank you

[@MichaelStepniewski]

Just search for fiber optic media converter.

[@NetworkAdvisor]

Thanks Michael. And, if it's just for your lab use, search Ebay.

[@leorudolph5707]

Hello, anyone knows a plier made to work with divisible connectors Ebm-gs?

[@AllYourBaseAreBelongToU5]

You didn’t cover FC connectors. Single mode can go up to 80km with ZR optics and further with use of DCMs. You should talk about Fiber Distribution Panels, too.

[@peteradams7457]

Didn't cover d4, APC-sc, apc-lc or biconic either

[@fight-newz]

Subbed..

[@NetworkAdvisor]

Thanks Mark. I’ll have to come check out your channels 😊

[@kingjeremysircornwell7847]

warts, transmit light? like a fiber optic cable.

[@NetworkAdvisor]

Ok. 😊

[@michael7324]

Pro tip: If you need to see the light in the end of the connector, use your cell phone camera. You will see the red light as a bright purple light that is easy to see. And it will cot damage youe eyes. This is much more of an issue when toy are looking at LR transceivers of transceivers up in the 100gb range.

[@NetworkAdvisor]

right? cracks me up to see so many techs staring right end to the end of the fiber (I'll admit I did that too in my younger (dumber) days. Neat trick about the cell camera. :-D

[@QuantumBraced]

SC are used on PONs, otherwise it's all LC now I think.

[@merrette]

SC =Stab n Click, ST = Stab n Twist, LC = Little Click

[@NetworkAdvisor]

Ha! I love that! 😄

[@StookyDoo22]

Don't go to the light

[@NetworkAdvisor]

ah hahahaha ‘. 😁

[@DogeGamer22]

hello

[@panshaojun7648]

Learn more.

[@slamdvw]

quick and dirty - you can use your phone's camera to "see" the IR light coming out of the transceiver or fiber.

[@NetworkAdvisor]

Huh? Have to try that. Thanks for sharing. 😊

[@fibertti4469]

Learn any more~
