Yeah, that's way too expensive. The fibre which came with my two samples was just a thick plastic fibre - same quality as the stuff used for fibre optic lamps at the time, I figure. Here in Oz there are people using POF for ethernet, and patch cords seem to be a stock item: http://www.afwtechnologies.com.au/plastic_fiber.html The prices here are more manageable if you ignore the terminated cable, and go for bare: http://au.element14.com/fiber-optic-cable However, I'd expect the stuff used for low tech purposes to be cheaper: http://www.opticfibrelighting.com.au/category_oflfibrecable And when the needed range isn't likely to exceed 3 metres, and the end-emitting stuff seems to be jacketed (giving mechanical protection), then I suspect it might be the most economical choice. The 2.5 mm diameter stuff would plug straight into the Tx/Rx units, if my memory of their size is right. There must be more sources up there where it snows, than down here - we import the stuff, I'm certain.
