General Consideration: It is generally not recommended to run fiber optic cables in the same conduit as electrical power cables. This is due to several potential risks and complications that can arise from such an arrangement. Electrical Interference: Electrical cables can produce electromagnetic. The existing 2" conduit contains 4x 1/0 XLPE cable (rated for direct-burial), so I plan on pulling outdoor rated, non-metallic fiber through the same conduit. My original plan was to trench new conduit and run CAT8, but given that the existing run is all "customer side" and installed by the former. "When setting up a new communication network or electrical system, one common question arises — can fiber optic cables and power cables run together?" "The answer is yes, they can — but only when certain safety and technical guidelines are followed. As per KSA regulations where NEC and IEC standards are being followed Under British regulations I'm not aware of anything which prohibits LV. When optical fibers are within the same composite cable for electric light, power, Class 1, non?power-limited fire alarm, or medium-power network-powered broadband communications circuits operating at 600 volts or less, they shall be permitted to be installed only where the functions of the optical. One way round this is to install aerial fiber cables close to power lines, such as on mixed use poles which also carry electricity. Obviously, these fiber cables need to be resistant to electricity, which can be difficult as many aerial cables contain high tensile steel (HTS) for tensile strength.
