Abstract
Systems and methods are described that derive a relationship between an optical transmitter's extinction ratio (E) and its interferogram wing-to-peak ratio (I). The change in an optical transmitter's Icorrelates with a change in measured E. As the Eof a telecom signal changes, the power of the modulated signal's interferogram wings change. After a relationship between Iand measured Ehas been derived for an optical transmitter, the relationship may be used after deployment to determine an Eby measuring an I.
