Learn why Extinction Ratio (ER) is critical in optical transceivers. Understand how ER impacts receiver sensitivity, BER, and module performance.
The extinction ratio of an amplitude modulator is the ratio between the optical power at maximum and minimum transmission. Extinction ratios are dependent on the crystal employed.
One of the most important measurements in optical NRZ signaling, Extinction Ratio (ER) was often considered an unstable measurement. This has been corrected with the arrival of “ER Calibrated”
