We want to use the digital input in our ESD system . The digital input is coming from Fibre optic , is it ok to use. The distance between the digital input to the ESD is around 5 km. can we use hardwired cable instead of FO signal ?

The simple answer is yes. But, it must meet the recent (2020) harmonization of either USA's ANSI/ISA-84, or EU's IEC-61511.
In my experience that means the DI via Fiber-optic, may have to be redundant.
