Ubuso
• Ngasikhathi sinye sihlinzeka ngama-voltages ayisithupha ezenzakalelayo ezenzakalelayo ze-Dual Polarization IQ Modulators
• Ifomethi yokushintshanisa izimele:
I-SSB, QPSK, QAM, OFDM iqinisekisiwe.
• Xhuma futhi udlale:
Akukho ukulinganisa okwenziwa ngesandla okudinga konke okuzenzakalelayo
• Mina, izingalo ze-q: Ukulawulwa kwezindlela eziphakeme kanye nezindlela ezi-null eziphezulu zokuqothulwa: 50db max1
• I-P ARM I-PRAM: Ukulawula ku-Q + kanye Q- Izinhlobo zokunemba: ± 2◦
• Iphrofayili ephansi: 40mm (W) × 29mm (d) × 8mm (h)
• Ukuqina okuphezulu: Ukuqaliswa ngokugcwele kwedijithali kulula ukuyisebenzisa:
• Ukusebenza ngesandla nge-mini jumper 2
I-Oem Oem Oem eguquguqukayo nge-UART / IO
• Izinhlobo ezimbili zokuhlinzeka ngama-voltages e-bias: A.Automatic Bias bias control b.user echaze i-BASTTAGE
Isicelo

I-1 mer isho isilinganiso sokuqothula se-modulator. Isilinganiso sokuqothulwa sifinyelelwe ngokujwayelekile isilinganiso sokuqothulwa kwesimondi esichaziwe kwi-datasheet ye-modulator.
2VumelaVπ nisaka i-bias voltage ngo-180◦ na-VP nisaka i-voltage elungiselelwe kakhulu yamaphuzu we-quad.
3Uyacelwa ukuthi kuqashelwe ukuthi amandla okufakwayo okufakwa awabhekiseli kumandla okubona endaweni ekhethiwe ye-bias. Kungamandla aphezulu aphezulu aphezulu we-modulator angathumela kuwo isilawuli lapho kuvela ama-voltage voltage avela-Vπ Ukuze +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 nephuzu eliphakeme lizoshintshana. Iphuzu le-Q + ne-Q- lizoshintshana nomunye. I-Polar switch inika amandla umsebenzisi ukuthi ashintshe
polar ngqo ngaphandle kokushintsha amaphuzu okusebenza.

1 Ukukhetha okukodwa kuphela okuzokhethwa phakathi kokusebenzisa i-PhotoDode noma kusetshenziswa i-Modulator PhotoDiode. Kunconywa ukusebenzisa isilawuli PhotoDide socwaningo lwelebhu ngezizathu ezimbili. Okokuqala, i-controller Photodiode iqinisekise izimfanelo. Okwesibili, kulula ukuguqula ubukhulu bokufaka okukhanyayo. Uma usebenzisa i-photodiode yangaphakathi ye-Modulator, sicela uqinisekise ukuthi umphumela wamanje we-Photodiode ulingana 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.
