This is the incorrect part. Light losses in the

This looks like about state of the art for broad
spectrum optical fiber for lighting use, and with
ten meters surely enough to get the light through
the hull, 100 dB loss per kilometer over much
of the spectrum doesn't look like too much to
suffer.

If that's too much infra-red transmissivity, an IR
mirror could be put in front of the collection
surface, I suppose.

You may be working on old information.

Alternately, I may be entirely incompetent to read
that graph. I sure can't read the math in the formal
papers on Rayleigh scattering with much facility.
