Measuring Extinction Ratio of Optical Transmitters
Learn how to accurately measure the extinction ratio of optical transmitters. Application note for optimizing optical communication
OLT optical module extinction ratio
Commonly called out in optical telecommunication standards, ER is a measure of modulation depth, and can be used for example as a figure of merit of an optical modulator. This article. 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. P1 and P0 are represented by (binary 1) and (binary 0) respectively. In telecommunications, extinction ratio (re) is the ratio of two optical power levels of a digital. This white paper explains some of the benefits of highly accurate ER measurements in both 10 GbE (Ethernet), with its relatively low ER requirement, and in...
