Which of the following is considered a broad band communication channel?

  • A.Coaxial cable
  • B.Microwave circuits
  • C.Fiber optics cable
  • D.All of these

Broadband means a channel of wide bandwidth, and coaxial cable, microwave links and optical fibre all qualify - each carries far more than a single voice channel.
