My optics sucks.. :(

I have some bare 1mm plastic optic cable..
You know..
Shine light in one end...see light at the other...

I have to put a jacket on the optic cable...
I plan on using wire insulation.. It's all I have handy..
I have black wire insulation but no white wire insulation..

Would I get more light transmission if I used white insulation?
The cable is 6ft long..

I think no matter what jacket I put on...Any high angle light will
bounce so much that it'll be eliminated by the reflective losses..
The dominant light that gets through is all from refraction.

Seems right..but I dunno for sure.

If it's a proper fiber, the jacket shouldn't make much difference at
all - the light is confined by reflecting off the inner surface
of the fiber - it never sees the jacket at all; only the losses,
and you'll never get them back anyway.

The jacket is for mechanical protection, but if all you want is
cosmetic, then you could paint the bare fiber.

Otherwise, either find something to dip it in like Plasti-Dip(tm),
or go ahead and thread the fiber through the tube of insulation
from a wire, or for that matter, spaghetti tubing, if you want
to go through all of that tedium.

Cheers!
