1. I-MER ibhekisela ku-Modulator Extinction Ratio. Isilinganiso sokuqothulwa esifinyelelwe ngokuvamile siyisilinganiso sokushabalala semoduli esicaciswe kudatha yemoduli.
2. Sicela uqaphele ukuthi amandla okukhanya okufaka awahambisani namandla okubona endaweni ekhethiwe yokuchema. Isho umkhawulo wamandla okubona imodulator engawathumela kusilawuli lapho i-voltage echema isuka ku-−Vπ iye ku-+Vπ .

1 I-Polar incike esignali yesistimu ye-RF. Uma ingekho isignali ye-RF ohlelweni, i-polar kufanele ibe iphozithivu. Uma isignali ye-RF ine-amplitude enkulu kuneleveli ethile, i-polar izoshintsha isuke ekubeni iphozithivu iye kwenegethivu. Ngalesi sikhathi, i-Null point kanye ne-Peak point zizoshintshana.Iphoyinti le-Q+ nephoyinti le-Q zizoshintshana futhi.Iswishi ye-Polar yenza umsebenzisi akwazi ukushintsha indawo epholile.
ngqo ngaphandle kokushintsha izindawo zokusebenza.
2Inketho eyodwa kuphela ezokhethwa phakathi kokusebenzisa i-photodiode yesilawuli noma ukusebenzisa i-modulator photodiode. Kunconywa ukusebenzisa i-photodiode yesilawuli ekuhlolweni kweLab ngezizathu ezimbili. Okokuqala, i-photodiode yesilawuli inezimfanelo eziqinisekisiwe. Okwesibili, kulula ukulungisa ukukhanya kokufakwayo.Uma usebenzisa i-photodiode yangaphakathi yemoduli, sicela wenze isiqiniseko sokuthi ukuphuma kwe-photodiode kuhambisana ngokuqinile namandla okufaka.
I-Rofea Optoelectronics inikezela ngomugqa womkhiqizo wamamojula wezohwebo we-Electro-optic, I-Phase modulators, Intensity modulator, Photodetectors, Laser light sources, DFB lasers, Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Light detector, Balanced driver photodetector, Laser , Fiber optic amplifier, Optical power meter, Broadband laser, Tunable laser, Optical detector, Laser diode driver, Fiber amplifier. Siphinde futhi sinikeze amamoduli athile athile ukuze enze ngokwezifiso, njengamamodulators wesigaba esingu-1*4 array, i-Vpi ephansi kakhulu, kanye namamodulators wesilinganiso sokuqothulwa okuphezulu kakhulu, asetshenziswa kakhulu emanyuvesi nasezikhungweni.
Sethemba ukuthi imikhiqizo yethu izoba usizo kuwe kanye nocwaningo lwakho.
