Fiiro gaar ah:
1* waxa loola jeedaa gelinta kala duwanaanshaha awoodda ee moduleka marka wax-soo-saarka modulatorku uu ugu badnaan yahay. Xakamaynta dhibcaha hoose ee modulator-ka oo leh saamiga sare ee baabi'inta, awoodda wax-gelinta waa in si habboon loo kordhiyo; Shuruudaha gelinta awooda gaarka ah, waxaad hagaajin kartaa isku-xidhaha gudaha iyo tilmaamayaasha faa'iidada wax-sheegaha, fadlan kala tasho iibka markaad dalbanayso dalabaadka.
2* Markaad dalbanayso dalabka, fadlan sheeg dhererka hirarka shaqada, kaas oo u baahan in la wanaajiyo iyadoo loo eegayo hirarka shaqada.
3* beddelka saamiga dabar goynta sidoo kale waxay ku xidhan tahay heerka saamiga bakhtiinta beddelka ee modulator-ka laftiisa.

1 Polar waxay kuxirantahay nidaamka RF signal. Marka aysan jirin calaamadda RF ee nidaamka, cirifku waa inuu noqdaa mid togan. Marka calaamadda RF ay leedahay baaxad weyn oo ka weyn heer gaar ah, dabaysha ayaa ka beddeli doonta togan una beddelmi doonta taban. Waqtigan xaadirka ah, Null point iyo dhibicda ugu sarreysa ayaa midba midka kale isweydaarsan doona. Q+ dhibic iyo Q- dhibic sidoo kale way isweydaarsanayaan.
si toos ah iyada oo aan la beddelin dhibcaha hawlgalka.
2Kaliya hal doorasho ayaa la doortaa inta u dhaxaysa isticmaalka kontoroolka photodiode ama isticmaalka modulator photodiode. Waxaa lagu talinayaa in loo isticmaalo kontoroolka photodiode ee tijaabooyinka shaybaadhka laba sababood dartood. Marka hore, kontaroolaha photodiode ayaa xaqiijiyay tayada. Marka labaad, way sahlan tahay in la hagaajiyo xoogga iftiinka wax gelinta. Haddii la isticmaalayo modulator's photodiode gudaha, fadlan hubi in hadda soo-saarka photodiode uu si adag ula siman yahay awoodda wax-gelinta.
Rofea Optoelectronics waxay bixisaa khadka wax soo saarka ee modulators Electro-optic, modulators wajiga, modulator xoojinta, sawirqaadayaasha, ilaha iftiinka laser, DFB lasers, amplifiers indhaha, EDFA, laser SLD, modulation QPSK, laser Pulse, Light detector, sawir-qaade dheellitiran, darawalka laser. , Fiber optic amplifier, Mitirka awoodda indhaha, Laser Broadband, Laser Tunable, indhaha, Diode darawalka Laser, Fiber cod-weyni. Waxaan sidoo kale siinaa wax-bedelayaal badan oo gaar ah oo loogu talagalay habeynta, sida 1*4 modulators wejiga array, Vpi aadka u hooseeya, iyo modulators saamiga baabi'inta aadka u sarreeya, oo inta badan lagu isticmaalo jaamacadaha iyo machadyada.
Waxaan rajeyneynaa in alaabtayadu ay ku caawin doonaan adiga iyo cilmi-baaristaada.
