1. I-MER ibhekisa kwiModulator Extinction Ratio. Umlinganiselo wokuphela ofunyenweyo udla ngokuba ngumlinganiselo wokuphela kwemodulator ochazwe kwiphepha ledatha lemodulator.
2. Nceda uqaphele ukuba amandla okufaka e-optical awahambelani namandla okukhanya kwindawo ekhethiweyo ye-bias. Ibhekisa kumandla okukhanya aphezulu anokuthunyelwa yi-modulator kwi-controller xa i-voltage ye-bias isuka kwi-−Vπ ukuya kwi-+Vπ.

1 I-Polar ixhomekeke kwisignali ye-RF yenkqubo. Xa kungekho signali ye-RF kwinkqubo, i-polar kufuneka ibe ntle. Xa isignali ye-RF inomlinganiselo omkhulu kunomgangatho othile, i-polar iya kutshintsha ukusuka kwi-positive ukuya kwi-negative. Ngeli xesha, i-Null point kunye ne-Peak point ziya kutshintshana. I-Q+ point kunye ne-Q- point ziya kutshintshana. I-Polar switch ivumela umsebenzisi ukuba atshintshe i-polar
ngokuthe ngqo ngaphandle kokutshintsha iindawo zokusebenza.
2Kuza kukhethwa ukhetho olunye kuphela phakathi kokusebenzisa i-photodiode yokulawula okanye ukusebenzisa i-photodiode yokulawula. Kucetyiswa ukuba kusetyenziswe i-photodiode yokulawula kwiimvavanyo zeLabhoratri ngezizathu ezibini. Okokuqala, i-photodiode yokulawula iqinisekisile iimpawu. Okwesibini, kulula ukulungisa amandla okukhanya okufakwayo. Ukuba usebenzisa i-photodiode yangaphakathi ye-modulator, nceda uqinisekise ukuba umsinga wokuphuma we-photodiode uhambelana ngqo namandla okufaka.
