Guide Measuring Extinction Ratio of Optical Transmitters
The extinction ratio calibration page will indicate whether a calibration is recommended, why it is recommended, and the conditions under which any current calibrations have been performed.
Guide Extinction Ratio (ER) Calibrated
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”

The test is performed using calibration particle standards, known as polystyrene latex spheres (PSLs), with two sizes: one that is close to the minimum detectable reported size range and another that is
Guide Extinction Ratio
To minimize extinction ratio measurement errors due to offsets, first perform a dark calibration. The vertical scale setting affects the magnitude of the dark level offset. For best accuracy, perform the
Guide Transmitter for Calibrating Extinction Ratio Measurements of
As a first step to providing such a service, we describe a transmitter being developed at NIST for calibrating the extinction ratio of optical receivers. The transmitter makes use of a laser source and
Guide What is Extinction Ratio (ER) and Why Does It Matter
This article explains what extinction ratio is, why it matters for reducing bit error rates in optical communication, and how it impacts optical module performance.
