When we're talking about #transceiver, we generally look at the Optical Power Budget to determine the distance that is achievable. But we should also be aware of the so-called Extinction Ratio of our signal.
In this #brainsnack video James F. Merchant explains what it is, how it relates to OMA (not what our German speaking friends may think) and why you should be aware of these aspects.
Keep in mind - the optical power does not say anything about the optical amplitude!
