Drag and Drop Question Drag and drop the characteristic from the left onto the cable type on the right. Answer:
The correct answer is is ideal over longer distances with little loss of integrity; is typically used for DWDM optical systems spanning long distances; uses a single wavelength on light; has a core diameter of either 62.5 or 50 microns. Single-mode fiber (SMF) is ideal over longer distances with little loss of integrity because its narrow core (~9 microns) allows light to travel in a single path with minimal dispersion, and it uses a single wavelength of light. SMF is also the standard choice for DWDM (Dense Wav

- uses a single wavelength on light
- has a core diameter of either 62.5 or 50 microns
Explanation
Single-mode fiber (SMF) is ideal over longer distances with little loss of integrity because its narrow core (~9 microns) allows light to travel in a single path with minimal dispersion, and it uses a single wavelength of light. SMF is also the standard choice for DWDM (Dense Wavelength Division Multiplexing) systems spanning long distances due to its low attenuation and high bandwidth capacity. Multi-mode fiber (MMF) uses a larger core diameter of either 62.5 or 50 microns, allowing multiple light modes to propagate simultaneously, which is suited for shorter distances.
