If you don't use SFP modules and instead drive the laser diode directly, they can transmit an enourmous bandwidth (up to several GHz) of analog signals.
Even more fun: The receivers can be passive, basically a tiny little solar cell, outputting enough RF energy to be picked up as RF signals by a regular receiver.
This is how coax television on GPON systems is sometimes done.
