Assuming you mean single mode fiber optic cable,
one source is Thorlabs - http://www.thorlabs.com/
They have SM cable for visible through IR, but I
doubt that for distances of one or two metres it
will make much if any difference.

Thank you Tom. What I am trying to do is make an object
beam from a place I can't fit a mirror. So I need a fiber
that does not change the polarizaton. Can you recommend
one? They offer about 50.

On p. 298 of their catalogue they have some 3M
single mode polarization maintaining fibers, for example
FS-PM-4611 for 820 nm, $13.23 per meter. Much
cheaper than the Lucent PM fiber (p.308) at $32/m.
Caveat - I have no idea how well this stuff would
work in a holography setup, or even whether for
very short cables you really need the PM cable,
or single mode for that matter. Optics is not really
my field of expertise. 24.67.253.203

Thank you Tom. I talked with Thorlabs and the attenuation
at 658nm would make this cable unsuitable. The only thing
thay can offer is to post polarize the beam with a
polarization controller for $3,9995.00! I'll keep
searching. I guess if I had enough power I could just put a
polarizer in front of the output from the cable. 64.167.150.182
