Which outcome results from excessive optical return loss within a fiber optic communication system?

💡 Explanation

Excessive optical return loss leads to increased laser RIN noise because back-reflected light interferes coherently with the laser cavity, enhancing its relative intensity noise via the *multiple reflections* mechanism. Therefore, lasers have an increase of noise, rather than experiencing advantages of alternatives under normal transmission conditions.
