Fibre-optic lines are tapped by bending the line over a prism and reading
the spillover from the cable. In some cases this can be done without
stripping back the cladding. In all cases the tap can be located using a
TDM( Time Division Multiplexer). If you place your splice within a few
meters of a coupler it will be harder to detect. All this can be done today
and without interupting the service of the client. I would be happy to
answer most technical questions regarding fibre-optics since this is what I
do for work...
I am not aware of any device which will tap a fibre remotely yet...
