1 MER waxa ay tilmaamaysaa Saamiga Dabar goynta Modulator-ka gudaha. Saamiga dabar goynta la gaarey waa sida caadiga ah saamiga baabi'inta modulator-ka ee lagu qeexay xaashida xogta modulator-ka.
2AllowVπ ku muuji danabka eexda 180◦ iyoVP ku muuji danabka eexda ee ugu wanagsan ee dhibcaha Quad.
3Fadlan la soco in takhaatiirta wax gelinta ahi aanay tixraacin awoodda indhaha ee barta eexda ee la doortay. Waa awooda ugu badan ee indhaha uu modulator-ku u dhoofin karo kantaroolaha marka korantada eexdu ka soo jeedo-Vπ ku +Vπ .

1 Polar waxay kuxirantahay nidaamka RF signal. Marka aysan jirin calaamadda RF ee nidaamka, cirifku waa inuu noqdaa mid togan. Marka signalka RF uu leeyahay baaxad weyn oo ka weyn heer cayiman, dabaysha ayaa ka beddeli doonta togan una beddelmi doonta taban. Waqtigan xaadirka ah, barta Null iyo dhibicda ugu sarreysa ayaa midba midka kale is beddelayaa. Q+ dhibcood iyo Q- dhibic sidoo kale way isweydaarsanayaan. Daboolka dabaysha ayaa awood u siinaya isticmaalaha inuu beddelo
polar si toos ah iyada oo aan la beddelin dhibcaha hawlgalka.

1 Kaliya 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 gelinta. Haddii aad isticmaalayso modulator's photodiode gudaha ah, fadlan hubi in hadda wax soo saarka photodiode uu si adag ula siman yahay awooda wax galinta.
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.
