Does armored underground fiber optic cable need to be grounded?

Hello all,

I cannot get a straight answer after hours of researching this topic. I plan on running a pre-terminated single mode fiber optic cable with armored tubing between two buildings (less than 35ft). I stumbled across some information that mentioned that the fiber should be grounded.

I was under the impression that fiber optic didn’t conduct electricity and is the ideal solution to be ran underground in PVC conduit between two buildings.

Thank you.
