Extinction ratio
In telecommunications, extinction ratio (re) is the ratio of two optical power levels of a digital signal generated by an optical source, e.g., a laser diode. The extinction ratio may be expressed as a
Extinction ratio of optical receiver
Extinction ratio references the difference between the energy of the positive level (transmitted 1) and the negative level (transmitted 0). The greater the ratio is, the wider the separation. The purpose of this application note is to show how the optical extinction ratio is defined and to demonstrate how variations in extinction ratio affect the performance of digital optical. One important parameter that is typically measured with an oscilloscope is extinction ratio (ER), which describes how efficiently laser transmitter power is converted to modulation power. ER is defined as the ratio of the average power used to transmit a logic level “1” to the average power used to. The Extinction Rat...
