I built an amplitude-modulated IR fiber link using cheap parts and got poor results due to fluorescent light leakage into the jacketed cables. I've tried hard to find available chipsets for S/P DIF but come up short. A well-shielded box or internal optical connection for radio would be a nice thing to have for ham equipment.
