Not really sure how. I have had heard of ways to tap a fibre optic link noninvasively, but its not related to Van Eck or anything like that. > > Harka > ___ Blue Wave/386 v2.30 [NR] > >

Anyway, the original post, as I recall, was about keeping sensitive data on a second hard drive, connected via (very thin, therefore harder to notice) fiber. Tempest monitoring was not a factor. -r.w.
