Unjacketed fiber exists, but since its primary use is to build up jacketed
fibers and fiber bundles, it is rarely seen in industry outside of the
companies which normally use it. But it is available. The fiber is usually
coated with a very thin layer of clear plastic to protect against moisture
and abrasion, and the diameter is around 0.5 to 1.0 millimeters in diameter.
Terminating fiber is specialized; it is cleaved using diamond tools, and is
usually polished after mounting in a holder. These days, transmitters and
receivers are easily available. For a relatively short run, plastic fibers
would probably be the best bet.
