A) Statistical time
B) Synchronous time
C) Frequency
D) Wavelength

Question

Quizplus · Accepted Answer

Wavelength division multiplexing (WDM) is the technique used to transmit multiple signals over a single fiber-optic line by using different wavelengths of light for each signal. This allows for high bandwidth and efficient use of the available fiber-optic capacity. Statistical time division multiplexing (STDM), synchronous time division multiplexing (TDM), and frequency division multiplexing (FDM) are not commonly used for fiber-optic transmission.
