Question

Select the correct statement(s) regarding optical signals.

A. Optical signals are susceptible to radio frequency interference (RFI).
B. Although optical signals are part of the electromagnetic spectrum, they have different properties/characteristics and operate at higher frequencies than RF signals.
C. Although optical signals are in the THz range, an RF antenna tuned to the proper frequency can collect an optical signal.
D. All are correct statements.

Answer 1

D. All are correct statements

Step-by-step 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.
