Correct, otherwise dirt and pieces of coating will pile up at the face of the cleaved fiber due to the wiping action, leading to transmission and reliability issues. It's less of an issue if the connector has the fiber going through all the way and you do clean the connector's face a final step, however if it's a rapid style connector with pre-polished fiber inside, you essentially seal all the dirt inside the connector between the two fiber strands.
@@jeffteng2343 It's actually entirely wrong for another two reasons. On top of what others have said about dirty fiber causing the cleaver to cleave improperly, the cleanest that glass will ever be is after cleaving it. Cleaning a fresh cleave makes it worse.
The second coding is NOT cladding it’s the 260 micron primary buffer coating, the core glass and the cladding glass are something you never strip mostly because it’s not possible.
The cladding and core are necessary components for the fiber optic to work as intended. Light is a wave, and the fiber optic acts as a transmission line, not unlike a waveguide that is used for radio and RF. Actually technically the fiber could work without cladding as air provides the same transmission line discontinuity as the cladding does (causing internal reflection) but it would be too thin to handle.
In order to know it's going to work you need a fiber light passing through... Fiber is not easy to terminate due to the fact that terminating like this doesn't work unless you have years of experience and don't need a fiber light on the other end to ensure the light is passing through.
A quick test with a fiber power meter should work. If you're concerned about the splices and the terminator you can run a full OTDR test to confirm power and losses at each splice point back to the cabinet. Fiber termination is much more reliable than in previous decades.
I'm brand new to this! done copper for years and years. There seems to be very little information easy to find for beginners. When do you have to use glue/epoxy in the connectors? and when do you need to polish the ends? Are people just being lazy and not doing it witch cheap connectors and cheap cleavers? Or is this more something you have to worry about with multimode and long distances and worrying more about losses? Whereas with multimode/local stuff people just are not worrying about this?
Has nothing to do with if it’s multi mode or single. The glue and polishing is for anaerobic type connectors, these are quick connectors. Quick connectors, aka unicams, already come from the factory with an index matching gel inside the connector so all you need to do is put your clean fiber inside and you’re good to go.
I am kinda in the same boat, I have a lot of networking background, I look after a plethora of switches, routers, etc etc. I have crimped 1000s of rj45 connectors in my life but have yet to crimp a fibre lead. I am currently working at a company that use a mix of LC, SC and ST connectors which I need to make sure if they are ever damaged they can be repaired in house. The fibre paired are used to connect various buildings on quite a large site. So need to find good guides like this, luckily I have lots of test equipment to play around with to get some skills just incase I ever have to do it for real.
@@MrAbdullah773 You want all the cladding off before trying to cleave. If there is cladding on the cleaver won't cleave properly. So it either won't cut or it will leave a crappy edge that will give high light loss.
@@MrAbdullah773 He is right! The fiber needs to be clean before the cleaving. Cleaning after the cleaving will just damage the cleaved front end of the fiber. Try putting the fiber into a splicer to see the cleaved end and you will know what I mean
No disagreement in essence, just adding for the sake of clarity for beginners passing by that you generally can't strip all of the 900um buffer at once without breaking the fiber, so it is common practice to strip it in small sections. Fully agree with a single strip to remove the inner buffer coating so as not to risk any undue effects to the cladding. If the fiber will tolerate it, I do try to make my last section of 900um stripping longer than the cleave length of the fiber so that the cleave isn't near a spot the stripper jaws closed around. Gives me more consistent results. And be sure to properly dispose of your glass!
Oh boy.... Do you have any friends??? Not horrible... Real world... Not all of us have all day to make everything "just so".... I have never had a termination fail so it can't be all that bad...
Major wrong step: The cleaning needs to be done after stripping the fiber and before the cleaving
You surprised me with cleaning the fiber after cleaver.
@@rondog699 Never had that problem.... I was taught to "clean then cleave" so the tip is virgin glass..
YES that really bugged me, always clean your fiber before you cleave 🤦🏻♂️

This is what I was looking about and asked many no one answered me right , does cladding remove or no or the last layer we remove it is couting

This video makes it look super easy. Thanks for the video, do you have a link to this kit?
Thank you for this video. What’s the name of the tool that you’re removing at 4:45?
They are typically called electricians shears or Kevlar shears.
That “tool” is only on fast connects…not on all connectors

These are mechanical connectors that are already polished. No need for glue or polishing.

Yes, i am working in Germany, first cleaning and than cutting
Whooooa. You cleaned after the cleave. 🤦🏾♂️🤦🏾♂️
😂
Instructions not clear, got soldering iron stuck in the cleaver tool.
this is the very best way of terminations, many thanks
Should’ve cleaned after the cladding not the cleave.
I'm not sure why it was stripped so far. Most of that gets cleaved off.

Good lecture

Clean before you cleave , nothing is cleaner than freshly cleaved glass IMHO
can om3 connection be used on om4.
Yes
You made the process so easy but you forgot to mention wearing a safety glass.
Spit works just as good as the alcohol made over a thousand splices over the years with no issues

Cool it Joey... We ain't talkin about that tip..
Dead ass. Same here. Wipe that shit with my finger and it works just fine.
Never angle the strippers, never run the strippers more than once, you clean after stripping not before. Horrible example...
