Which is more suitable for industrial control, optical fiber or can bus?

Thank you for your invitation. Let me tell you my opinion:

Seriously, CAN bus and optical fiber are not comparable, and there is no relationship between who can simply replace who. CAN bus is a kind of control system and field bus, with upper communication protocol. Optical fiber is a kind of material and a way of data transmission. Its advantages are high data transmission speed, low loss and low interference. If you feel that your communication distance using CAN bus is limited, you can first convert it into an optical signal and transmit it in the optical fiber line, and then convert it back to other places. CAN bus and optical fiber are often used in industrial fields, but if the scope is limited to industrial control, then CAN bus is undoubtedly a better choice, do you understand?
