QuestionQ32

AI Overview

In theory, a multiplexer is equivalent to a demultiplexer; the sole difference is the direction of their optical-signal inputs and outputs.

  • A TRUE
  • B FALSE
Explanation

A multiplexer combines optical channels and a demultiplexer separates those channels. Because these are inverse functions, the same passive optical arrangement can theoretically operate as either device when the direction of signal propagation is reversed.
