Re: How to strip a 9 micrometer singlemode fiber?

Hi Guys,

I have bare singlemode fiber with a core diameter of 9 micrometer and a
cladding of 125 micrometers. I want to strip out or remove the cladding
to get the core exposed. I have tried strippers, but I can only get it
stripped into a diameter much larger than 9 micrometers.

Does anybody know how to complete this strpping job? Thanks a lot!


It is not necessary to strip the single-mode core and not advicable,
since you will get a fiber tip that can vibrate.

Just make a clean brake with a fiber cleaver of core/cladding.

You can also cement the fiber to selfoc-lens coated on the air-side
and uncoated on the fiber side (since the cemented surfaces have to be
uncoated).

You are sure that you focus on the core correctly when you get a
single mode beam out of the fiber (when you have collimated again with
a lens). The multimode core wont produce a beam, - you can just make
an image of the fiber output face. It will contain a lot of speckle.
The single mode fiber output has no speckle.

It is easier of course with visible light. But there are some infrared
viewers.

best regards
