Re: Fiber optic vampire taps

What we did at another location was to run the network inside of piping
and the pipes were then pressurized.  Then monitor the pressure. 
Tapping the 'net without causing a drop in pressure was not trivial...  
;-)  YOu didn't mention the run.

To all who are following this thread:

My main interest in strating this thread was to determine whether the
possibility of unobtrusive fiber tapping should be taken into account
when designing physical security for the fiber line.

Based on the replies I think it is fair to say that this type of
fiber tapping is probably a very remote possibility.  Of course data
between the endpoints will be encrypted and there is a high level of
security at each end.  Physical security methods are going to be
employed on the fiber line itself.

Thanks for all of the replies, especially those of you who actually
spent some time looking into this stuff.

Regards,

Nick Iglehart
