Is a higher extinction ratio for optical modules always better
Extinction ratio shows how well a system tells strong signals from weak ones. ♦ What is the Extinction Ratio (ER)? Extinction Ratio (ER) is the ratio of the optical power when the. In simple terms, the extinction ratio is the ratio of the optical power in a logical '1' bit (P1) to the power in a '0' bit (P0). A high ER means your '1's are really bright and your '0's are really, really dim.
