They suggest these

what length do you need to send over ?
this sort of stuff is a LOT cheaper and more rugged, and more than
capable of sending 10 MHz clock

and you just drive it with TTL.
Yeah, but those are piece parts. What would be nice is if a cheap "box"
could be found - ideally (for 10 MHz) BNC in/out and fiber connector
with a wall wart for power. Maybe this a good idea for a TAPR project if
someone was willing to do the design (!)
There's probably plenty of applications out there in amateur radio land
for a inexpensive RF over optical link with "decent" performance
(defined however).
