The laser diodes used in eg. CD players have a feedback photodiode,
sensing the laser's optical output.
If the lasers used for optical fibers have similar mechanism too, and if
the diode is sensitive to the light coming to it not only from the chip
but also from the fiber itself, and can
to splice into the
fiber. Hell, you don't even need a splice if you have access to the FDF
(Fiber Distributing Frame, or fiber patch panel).
