Wireless and wired networks are both susceptible to RFI.

Why is copper cabling susceptible to eavesdropping?

Because fiber-optic cabling uses light pulses instead of electrical signals, it is immune to interference and highly resistant to eavesdropping.

When copper wires are bundled together, they are susceptible to ____________, a form of interference where the signals leak out onto other wires.

A type of wireless network that uses light beams to send signals between two devices and is prone to interference from visible light sources is called ____________.

What are the three most common types of wireless communication and the frequencies they use?

An OPM measures the amount of __________ transmitted by a device and whether the amount meets the requirements for the device you're connecting.

What are the benefits of fiber-optic cabling?
