Burial fiber is like 20~40ct/m. Whether you can get a bucket wheel trench excavator through it at speed or have to dig by hand depends on what's in the ground and how hard the ground is, and how long the stretches are. Otherwise, it's like 10~20min to sufficiently properly terminate the fiber at the ends and that. You can likely get around that if you just order pre-terminated fiber at like 1$/plug and just plug it in at the ends instead of splicing. Sure, this will higher losses, but money. Fiber is literally cheaper than copper for >150m or >=10Gbit/s (though direct-attach cables up to 3~5m are even cheaper) if you can get by without field-terminating fibers.
