Which of the following is used to allow multiple sources on a single optical cable?

The correct answer is C. DWDM. DWDM (Dense Wavelength Division Multiplexing) is a fiber-optic multiplexing technology that combines multiple data signals onto a single strand of fiber by transmitting each signal on a different wavelength (color) of light. This dramatically increases the capacity of a single…

Explanation

DWDM (Dense Wavelength Division Multiplexing) is a fiber-optic multiplexing technology that combines multiple data signals onto a single strand of fiber by transmitting each signal on a different wavelength (color) of light. This dramatically increases the capacity of a single fiber. HSPA+ is a mobile broadband standard; MIMO (Multiple-Input Multiple-Output) is a wireless antenna technology; SONET is a time-division multiplexing standard for fiber that does not multiplex by wavelength.
