How does fiber optic security compare to copper cables?

Fiber optic security is notably superior to that of copper cables, particularly in terms of susceptibility to tapping and interference. This is primarily due to the unique properties of fiber optics, which use light to transmit data, rather than electrical signals.

The data transmitted through fiber optic cables is contained within the glass fibers and does not radiate electromagnetic signals as copper does. This significantly reduces the chances of external interference from electromagnetic sources, ensuring a more secure transmission. Additionally, intercepting the signal in fiber optic cables typically requires physical access to the cable, along with specialized equipment to detect light within the glass. This makes unauthorized access much more difficult compared to copper cables, where signals can be more easily tapped by accessing the electromagnetic field surrounding them. As a result, the design and operational principles of fiber optics inherently offer a level of security against signal tapping and external interference that copper cables cannot match.
