The higher the extinction ratio of the optical module the worse the receiving sensitivity
The value of the extinction ratio is not that the larger the optical module is, the better it is, but the optical module whose extinction ratio meets the 802. ♦ What is the Extinction Ratio (ER)? Extinction Ratio (ER) is the ratio of the optical power when the. The accuracy of the extinction ratio measurement can be affected by offsets, including the dark level, generated within the instrument electronics, typically following the photo diode. Offsets add to the incoming signal changing the values of the one and zero levels.
