What key advantage does fiber-optic cable have over copper cable?

Fiber-optic cable has a significant advantage in terms of higher resistance to electromagnetic interference compared to copper cable. This characteristic is vital for delivering reliable data transmission, especially in environments where electromagnetic interference (EMI) from other electrical devices can disrupt signals. Fiber-optic cables use light to transmit data, which is inherently immune to EMI, as opposed to copper cables that transmit data as electrical signals, making them vulnerable to interference from nearby cables, machinery, or wireless signals.

The ability of fiber-optic cables to maintain signal integrity over longer distances and in challenging conditions is a major reason why they are increasingly preferred for high-performance data transmission needs. This immunity allows for clearer signals and fewer errors in data communication, which is crucial for applications requiring high bandwidth or low latency.
