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.

No.
Transmitting light via fiber doesn't emit EM.
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.
