1. MER yerekeza ku gipimo cyo kuzimira kwa Modulator. Igipimo cyo kuzimira cyagezweho ubusanzwe ni igipimo cyo kuzimira kwa modulator kivugwa mu rupapuro rw'amakuru rwa modulator.
2. Menya neza ko imbaraga z'urumuri zinjira zidahuye n'imbaraga z'urumuri ku gice cyatoranijwe cya bias. Bivuga imbaraga ntarengwa z'urumuri modulator ishobora kohereza kuri controller iyo voltage ya bias iri hagati ya −Vπ na +Vπ.

1 Polar iterwa n'ikimenyetso cya RF cya sisitemu. Iyo nta kimenyetso cya RF kiri muri sisitemu, polar igomba kuba nziza. Iyo ikimenyetso cya RF gifite amplitude irenze urwego runaka, polar izahinduka kuva kuri nziza ijya kuri negative. Muri iki gihe, Null point na Peak point bizahindukana. Q+ point na Q- point bizahindukana. Polar switch ifasha umukoresha guhindura polar
mu buryo butaziguye hatabayeho guhindura aho ibikorwa bikorerwa.
2Hazatorwa amahitamo amwe gusa hagati yo gukoresha photodiode igenzura cyangwa gukoresha photodiode igenzura. Ni byiza gukoresha photodiode igenzura mu igerageza rya laboratwari kubera impamvu ebyiri. Ubwa mbere, photodiode igenzura ifite ubwiza buhamye. Icya kabiri, biroroshye guhindura ubukana bw'urumuri rwinjira. Niba ukoresha photodiode y'imbere ya modulator, nyamuneka menya neza ko umuvuduko w'urumuri rwa photodiode ujyanye neza n'imbaraga zinjiye.
Rofea Optoelectronics itanga umurongo w'ibicuruzwa bya modulators za Electro-optic, Phase modulators, Intensity modulator, Photodetectors, Laser sources, DFB lasers, Optical amplifiers, EDFA, SLD laser, QPSK modulation, Pulse laser, Light detector, Balanced photodetector, Laser driver, Fiber optic amplifier, Optical power meter, Broadband laser, Tunable laser, Optical detector, Laser diode driver, Fiber amplifier. Dutanga kandi modulators nyinshi zihariye zo guhindura, nka 1 * 4 array phase modulators, ultra-low Vpi, na ultra-high extinction ratio modulators, zikoreshwa cyane cyane muri za kaminuza n'ibigo.
Nizeye ko ibicuruzwa byacu bizagufasha no gukora ubushakashatsi bwawe.
