my experience so far with unifi
1) cable broken between tiang n the black box (~15m) (cause? monkey), unifi come and replace cable between tiang to wall (~10m), then splice it. FOC
2) cable broken again, same reason as (1), unifi come and replace the same length again, same process. FOC
3) same reason as above, this time replace whole length, with extra few meter. FOC
every time FOC because its before the black box.

last year a rat bite broken my fiber  in the house near the modem .
made a service report .
unifi tech came  and  fix for free. 

mine have a fiber termination box at back wall of my house.

then the white fiber  to my modem .

since this cable was bitten .

they instal  a small white box  . near my modem .

connect a plug to the broken  fiber  end .
and a patch cord  from this white box to my modem .
