1. I-Mer isho isilinganiso sokuqothulwa kwesimondi. Ukuvuselelwa kokuqothulwa kufinyelelwe ngokujwayelekile isilinganiso sokuqothulwa kwesimondi esichaziwe kwi-datasheet ye-modulator.
2. Sicela ubongelwe ukuthi ukufaka amandla okufakwayo akuhambelani namandla okubona endaweni ekhethiwe ye-bias. Kusho amandla aphezulu aphezulu aphezulu okuthi i-modulator angathumela isilawuli lapho ama-voltage voltage avela ku-VπST e-Vπ.

I-1 polar incike kwisiginali ye-RF ye-RF. Lapho kungekho siginali ye-RF ohlelweni, i-polar kufanele ibe nethemba. Lapho isinali ye-RF ine-amplitudwance enkulu kuneleveli ethile, i-polar izoshintsha ibe yinhle ibe yimbi. Ngalesi sikhathi, iphuzu le-null kanye ne-peak point lizoshintshana nge-getne.q + iphuzu kanye ne-Q- lizoshintshana lizoshintshana futhi lishintshe umsebenzisi ukuthi ashintshe i-polar
ngqo ngaphandle kokushintsha amaphuzu okusebenza.
2Ukukhetha okukodwa kuphela okuzokhethwa phakathi kokusebenzisa i-controller photodiode noma ukusebenzisa i-modulator PhotoDiode. Kunconywa ukusebenzisa isilawuli PhotoDide socwaningo lwelebhu ngezizathu ezimbili. Okokuqala, i-controller Photodiode iqinisekise izimfanelo. Okwesibili, kulula ukuguqula ubukhulu bokufakwa kokukhanya.Uma usebenzisa i-photodiode yangaphakathi ye-modulator, sicela uqinisekise ukuthi okukhona okukhona kwamanje kwe-Photodiode kulingana ngokuqinile kumandla okufaka.
I-ROFEA Optoelectoronics inikezela ngomugqa womkhiqizo we-Electro-optic Moderators, ama-modulators esigaba, ama-photodeter, umtshina we-LASES, i-PhotoDetor, umshayeli we-fiber, umshayeli we-fiber optic amplifier, amamitha abanzi, ebanzi I-Laser, i-laser eguqukayo, umtshina we-optical, umshayeli we-laser diode, i-fiber amplifier. Siphinde futhi sinikeze ama-modulators amaningi enziwe ngokwezifiso, njengama-1 * 4 array isigaba modulators, i-Ultra-Low VPI, kanye ne-Ultra-High
Ngiyethemba imikhiqizo yethu izokusiza wena nocwaningo lwakho.
