What are two advantages of using fiber optic cables compared with copper cables? (Choose two.)
- They are less expensive.
- They support higher bandwidth.
- They provide connections over longer distances.
- They use electromagnetic signals to transmit data.
- They provide shared media access for a single link.
Explanation: Data can travel longer distances on fiber optic cables, and the cables can support higher bandwidths than can copper cables. Using fiber optic cables, the sending device transmits the binary bits as light pulses using LEDs or lasers. The receiving device uses photodiodes to detect the light pulses and convert them to voltages. Fiber optic links are typical point-to-point links and they are more expensive than copper cables
