Dear friends, I have a 200 micron fiber ( 200 micron core/ 220 micron clad/ 250 sheath) the splicing machine we have is capable of splicing the same. however we are unable to cut the fiber ( after removing the sheath) flat. The cleavers provided with the splice machine is meant only for 125 micron max. can anybody suggest a way to cut fiber flat..... also is it possible to use some laser to cut the fiber, for the same? regards Pandian, research scholar, Fiber optics, IGCAR, India

For such a huge fibre I'd just try with a good old simple axe cleaver. Don't know if you still get them commonly anymore...wait a minute... one of my suppliers has something similar in a catalogue as cleave pens.

FIS has several options

see under tools- then scribe tools
This is basically a sharp sapphire blade in a handle.
with a bit of practice you can achieve reasonable perpendicular cuts. One clean touch of the blade to the fibre about 10-15mm from the fibre end then gently bend the fibre to encourage crack propagation.
Given that the fibres are highly multimode, as long as you have a reasonable cleave (not perfect) and good splice parameters for this fibre then the losses should still be OK
