Why each option
Fiber optic cable is the best choice for a factory environment with large electrical equipment because it is immune to electromagnetic interference (EMI).
Coaxial cables are copper-based and, while they have some shielding, are still susceptible to electromagnetic interference, especially in environments with large electrical equipment.
Cat 5 cables are unshielded twisted pair copper cables and are highly susceptible to electromagnetic interference, which would lead to significant networking issues in a factory environment.
Cat 6 cables are also unshielded or shielded twisted pair copper cables, offering better performance than Cat 5 but still susceptible to significant electromagnetic interference in environments with large electrical equipment.
Fiber optic cables transmit data using light signals through glass or plastic fibers, making them completely immune to electromagnetic interference (EMI) and radio-frequency interference (RFI). This immunity is crucial in factory environments with heavy machinery and electrical equipment that generate significant EMI, which can degrade or disrupt copper cable signals.
