fiber termination - practical help please |
|
|
Hello there,
I'm trying to terminate a 62.5/125 um fiber using the 3M Crimplok
Termination Kit and SC multimode connectors (6900). I'm doing this for
the first time and for some reason are unable to push the fiber through
the connector. It simple won't get through, not even with brute force
(I know you shouldn't do this). It seems to me that the hole is not big
enough for the fiber. Could anyone please help me with this? Any advice
is greatly appreciated!
Kind regards,
Nicole |

could be a couple things. I believe the Crimplok is not a
'puck-n-polish' so it's not supposed to go all the way through. If you
are stripping the fiber to the appropriate length, when it stops, that's
it. It shouldn't take any force at all. Which leads to the other
possibility, you're not stripping off enough of the cladding, and it is
obstructing the entry.

What kind of buffer the fiber is in?
If it's a 900 mkm buffer, then it has a 250 mkm layer of acrylic, which is
pretty dense and visually not distinguishable from 125 mkm glass. It may
be the case that you are not stripping all the plastic off, but leaving
the 250 mkm layer on, which is why the fiber won't go in. Make sure you
remove all the plastic. If you do, the fiber's glass diameter (125 mkm)
becomes visually very similar to that of a human's hair. If you leave the
250 mkm layer on, you'll easily see that it's too big when compared to the
hair.

Thank you very much for your advice, Dmitri! That is exactly what
happened, I haven't pressed the jacket remover tool down hard enough to
remove the acrylic layer. Brilliant, now I'm a step closer :o)
