Question

Select the correct statement(s) regarding optical signals.

Answer 1

Answer:

D. All are correct statements

Explanation:

Remember, an Optical signal is a type of electromagnetic signal, and so it is possible for radio frequencies to be converted or received into optical signals since they both use a form of electromagnetic waves or signal.

Indeed, Optical signals have different properties/characteristics and operate at higher frequencies than RF signals. For example, it uses a Near-infrared band (wavelength) of 800 nm - 1600 nm which is different from RF signals.

In addition, by using a Mach-Zhender Modulators (MZMs) an RF antenna tuned to the proper frequency can collect an optical signal.
