Which constraint causes increased crosstalk in optical multiplexing?

💡 Explanation

Insufficient wavelength separation in wavelength division multiplexing leads to crosstalk because the **optical filter overlap** allows neighboring channels to interfere, therefore increases crosstalk, rather than a clean separation, creating data corruption. Increased photodiode effects signal instead.
