Critical bending radius of optical fibres

[OrangeYogi]

Hello,

How do I calculate the critical bending radius of a single mode optical fibre? I'm using a polyimide coated fibre with coating diameter of 155μm. The wavelength is 1550nm.

Let me know if you have any questions.

Thank you

I would be looking at the manufacturers spec's for the fibre that you have

That was my first thought as well...

I agree. That will be highly dependent on the exact composition of the fiber and cladding material. Glass and polyimide are broad categories.
