Final answer:

Multimode fiber optics can transmit multiple signals simultaneously and have a larger core diameter than single-mode fibers. However, they do not offer a higher bandwidth or longer transmission distances than single-mode fibers, and they are generally less expensive.

Step-by-step explanation:

When discussing the features of multimode fiber optics, several statements can be made about its characteristics:

  • Multimode fiber optics can indeed transmit multiple signals simultaneously. This is due to the mode of light; however, each signal can interfere with others, which is why it has a limited distance range.
  • The statement that multimode fiber optics have a larger core diameter compared to single-mode fiber optics is correct. The larger core size allows the transmission of multiple light modes.
  • Multimode fiber optics do not have a higher bandwidth compared to single-mode fiber optics. Single-mode fibers offer a higher bandwidth over longer distances because they carry only one light mode, which eliminates modal dispersion.
  • Generally, multimode fiber optics are less expensive than single-mode fiber optics. This is because the larger core diameter eases the coupling of light into the fiber, reducing the overall system cost.
  • Multimode fiber optics cannot transmit signals over longer distances compared to single-mode fiber optics. Single-mode fibers are better suited for long-distance communication due to the lack of modal dispersion and the narrower core that ensures a single path for light waves.
