-If I recall correctly, it can be tapped without distubing transmitted data.

-I remeber reading an article in Info World about a year ago about just such
-a method.  It seems that if you bend a FO cable at more than  90 degrees
-that about 20% of the signal will "bleed" out of the cable at the bend. 


But since this is to be used for a security system, wouldn't this 20% loss
of signal be noticed?  I think this is an excellent idea!  I just happen to
have some low-grade plastic fiber laying around - I think I'll use it!
