Safety of running fiber alongside electrical in underground
If you want to run the fiber through the same conduit as the electrical cable, and the fiber is "ADSS" or has absolutely no metal in it, then you are totally safe.

This technique takes a small, lightweight fiber optic cable and wraps it around or lashes it to the power line. The cable is called optical power attached cable (OPAC), and it is lashed to the power cable

While fiber optic cables generally are all dielectric and carry no electrical power, it may be necessary to work in areas that have installed electrical power cables and hardware.

Luckily, splicing them together is no problem—inexpensive, easy-to-use machines automatically and unerringly connect each fiber to its counterpart in the next cable with a single click.

All-Dielectric Self Supporting (ADSS) cables can be erected in close proximity to power transmission lines. This of course, allows for pole sharing, which of course, reduces installation costs and speeds

Aerial optical cable is suspended in the air from poles and/or support structures. Most often it is supported between poles by being lashed to a wire rope messenger strand with a small gauge wire.
Replacing Fiber Optics on Power Lines
Use an optical power-attached cable (OPAC), which is a small and lightweight cable that gets lashed or wrapped to energized power lines. So, there you have it – everything you wanted to
Review of the usage of fiber optic technologies in electrical power
The continuous development of power transmission networks has allowed for the widespread implementation of fiber optic technologies in power lines and supply systems.
Mixing Fiber and Power Lines in Aerial Fiber Deployments
One way round this is to install aerial fiber cables close to power lines, such as on mixed use poles which also carry electricity.
FIBER OPTIC CONSTRUCTION STANDARDS
Fiber optic cable sequential numbers are required at each pole location and vault wall. Sequential numbers will identify conduit length, and slack left in vaults and at poles.
