Optical module extinction ratio adjustment

Home / Optical module extinction ratio adjustment

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. If very little power is used to transmit a zero level relative to the one level power, the ER. Although specifications are defined by industry standards and test method-ologies loosely described, historically it has been. The optical modulation amplitude (OMA) of a signal is an important parameter that is used in specifying the performance of optical links used in digital communication systems.

The absolute lower practical limit on extinction ratio is approximately 3, which corresponds to an OMA to P0 ratio of 2. At this level one-half of the optical power is wasted.
