← TechnologyWhich consequence results when wavelength drift overwhelms free-space multiplexing?
A)Increased bit-error probability✓
B)Reduced antenna beam collimation
C)Photodiode saturation reduction
D)Local oscillator phase distortion
💡 Explanation
Increased bit-error probability follows when wavelengths shift excessively during optical communications because wavelength division multiplexing (WDM) overlaps channels, therefore adjacent signals interfere; rather than distinct signals getting resolved.
