Doesn't that make it vulnerable (detectable) to Tempest attacks?
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.
You could break the fiber and add a repeater (if you know enough about the light protocol). Plastic fiber can be cut with a pocket knife, glass requires a machine which will make a square cut and polish the end. Those machines are not yet cheap. ------------------------------------------------------------------------- Bill Frantz | Cave ab homine unius lebri | Periwinkle -- Consulting (408)356-8506 | [Beware the man of one | 16345 Englewood Ave. frantz@netcom.com | book] - Anonymous Latin | Los Gatos, CA 95032, USA
