Yes. I know of several commecial systems. If you only need to do a short
jump, then using fairly basic E/O-O/E equipment should work well
enought. It all depends if you want/can to roll your own or need to buy
a finished product (aka "buy this, and you will be fine!").
Stay of plastic "fiber" if you can. Go multimode at least.
