Free CompTIA Network+ N10-008 Practice Question

An enterprise needs to significantly amplify the data carrying capacity of its existing single-mode fiber optic lines to connect geographically dispersed data centers. The solution must support multiple separate light wavelengths to concurrently transmit numerous signals over the same physical medium. What is the most suitable multiplexing technique for achieving the highest bandwidth expansion and accommodating future growth without installing new fiber strands?

  • Coarse Wavelength Division Multiplexing (CWDM)

  • Dense Wavelength Division Multiplexing (DWDM)

  • Optical Time Division Multiplexing (OTDM)

  • Synchronous Optical Networking/Synchronous Digital Hierarchy (SONET/SDH) transport over DWDM
