What are two facts that differentiate optical-fiber cabling from copper cabling? (Choose two.)

Optical fiber patch cables are typically more expensive than copper patch cables due to the precision required in their manufacturing and connectors.

Optical fiber transmits light, not electrical current, and therefore cannot carry electrical power for Power over Ethernet (PoE) devices; PoE requires copper cabling.

Optical fiber transmits data using light pulses, which allows for much higher bandwidth and therefore greater throughput options compared to electrical signals over copper cabling.

Copper cabling can be more susceptible to electromagnetic interference (EMI) and RFI, and its performance can degrade significantly more with temperature changes affecting resistance, while fiber is immune to EMI.

Due to its light-based signal transmission and lower attenuation, optical fiber can carry signals over significantly longer distances without needing repeaters, unlike copper cabling which is limited by signal degradation.
