Are fiber optic cables desirable for their low resistance to electromagnetic noise?

Fiber optic cables are indeed desirable for their resistance to electromagnetic interference (EMI), which makes them less susceptible to noise compared to traditional copper cables. This characteristic allows fiber optics to transmit data with greater clarity and over longer distances without degradation, making them an excellent choice for high-bandwidth applications. The fact that fiber optic cables use light rather than electrical signals is fundamental to this property, as light is not affected by electromagnetic fields.

In contrast, copper cables can pick up electromagnetic noise, which can lead to data loss or signal degradation. Hence, the assertion that fiber optic cables have low resistance to electromagnetic noise is a misunderstanding of their capabilities. Rather, they are high-performing solutions specifically because they demonstrate this resilience to external noise, contributing to their increased reliability in various communication networks. This strength is a key reason why fiber optics are preferred in environments with significant electromagnetic interference.
