Extinction ratio of optical communication module
ER (Extinction Ratio) is the ratio of the average optical power when the optical module transmits a logic "1" to the average optical power when it transmits a logic "0". Generally expressed in logarithms, ER is a constant for a linear attenuation system. For a graphical description, the eye-diagram is commonly. The Extinction Ratio defines how distinct the “on” (logic 1) and “off” (logic 0) states of an optical transmitter are, making it a direct indicator of signal quality in optical transceivers. As design/test margins get tighter, the challenges of making accurate and repeatable extinction ratio measurements become more apparent.
