700km is too far to expect a dark fiber to do much good for you,
unless it is an erbium repeatered sea-bed type of fiber you lay
down yourself.

Two conventionally repeatered fibres, one in each direction, would be
a heck of a calibration task, requiring cooperation from a lot of
telco people to switch directions for the calibration, and even more
unlikely, that the telco people keep their hands off after the calibration.
