Default Talking of fibre

If you bend a fibre some of the light leaks out. A couple of weeks ago I
watched a fibre leased line being installed.
The bend radius looked like 2 or 3cm.

When I hired a fluke fibre tester, it came with a small "mandrel" about
that diameter which you wrapped a few turns of the fibre around for
testing, I think it was to attenuate the light that had taken a highly
reflected path through the fibre and only measure the more direct paths?
