Which destructive outcome reduces signal sensitivity in fiber-optic interferometers?

💡 Explanation

In fiber optic interferometers, polarization mode dispersion causes signal degradation because different polarization modes interfere destructively after traversing slightly different optical paths. Therefore, reduced sensitivity results, rather than signal enhancement from constructive polarization.
