How far should optical fiber be from electrical cable before installation
Separation should not be required, unless the fiber is required to survive and stay in service following a major arcing cable fault. You should advise your potential suppliers of your intended use. When there are two different voltage ratings on cables, separation, either mechanical or by distance, is to avoid an insulation breakdown of the higher rated cable from breaking down the insulation and entering the lower voltage system. Other than that you haven't provided much information, given. Generally speaking, fiber optic cable can be installed using many of the same techniques as conventional copper cables. 770 references sections in Chapter 2 and Art. Because fiber optic cables do not carry electrical currents or voltages they are totally immune to electromagnetic interference.
