1. I-MER ibhekisela ku-Modulator Extinction Ratio. Isilinganiso sokuphela esifinyelelwayo ngokuvamile siyisilinganiso sokuphela kwe-modulator esichazwe kudatha ye-modulator.
2. Sicela uqaphele ukuthi amandla okukhanya okufakwayo awahambisani namandla okukhanya endaweni ekhethiwe ye-bias. Kubhekisela emandleni okukhanya aphezulu kakhulu i-modulator engawathumela kumlawuli lapho i-bias voltage isukela ku-−Vπ kuya ku-+Vπ.

1 I-Polar incike esignalini ye-RF yesistimu. Uma kungekho signalini ye-RF ohlelweni, i-polar kufanele ibe yi-positive. Uma isignali ye-RF inobukhulu obukhulu kunezinga elithile, i-polar izoshintsha isuka ku-positive iye ku-negative. Ngalesi sikhathi, iphuzu le-Null kanye nephuzu le-Peak zizoshintshana. Iphuzu le-Q+ kanye nephuzu le-Q- nazo zizoshintshana. I-Polar switch ivumela umsebenzisi ukushintsha i-polar
ngqo ngaphandle kokushintsha izindawo zokusebenza.
2Kuzokhethwa ukhetho olulodwa kuphela phakathi kokusebenzisa i-photodiode yokulawula noma ukusebenzisa i-photodiode yokulawula. Kunconywa ukusebenzisa i-photodiode yokulawula ekuhlolweni kwelebhu ngezizathu ezimbili. Okokuqala, i-photodiode yokulawula iqinisekisile izimfanelo. Okwesibili, kulula ukulungisa ubukhali bokukhanya kokufaka. Uma usebenzisa i-photodiode yangaphakathi yomlawuli, sicela uqiniseke ukuthi ugesi wokukhipha we-photodiode ulingana ngokuphelele namandla okufaka.
