Fiiro gaar ah:
1* waxaa loola jeedaa gelinta baaxadda awoodda ee module-ka marka wax soo saarka modulator-ku uu ugu badan yahay. Xakamaynta barta hoose ee modulator-ka oo leh saamiga baabi'inta sare, awoodda gelinta waa in si habboon loo kordhiyaa; Iyada oo la raacayo shuruudaha gelinta awoodda gaarka ah, waxaad hagaajin kartaa tilmaamaha isku xidhka gudaha iyo qalabka ogaanshaha, fadlan la tasho iibka marka aad dalbanayso.
2* Markaad dalbanayso, fadlan qeex mowjadda shaqada, taas oo u baahan in la hagaajiyo iyadoo loo eegayo mowjadda shaqada.
Saamiga baabi'inta 3* sidoo kale wuxuu ku xiran yahay heerka saamiga baabi'inta beddelka ee modulator-ka laftiisa.

1 Polar waxay ku xiran tahay calaamadda RF ee nidaamka. Marka uusan jirin calaamadda RF ee nidaamka, polar-ku waa inuu noqdaa mid togan. Marka calaamadda RF ay leedahay baaxad ka weyn heer cayiman, polar-ku wuxuu ka beddeli doonaa togan una beddelan doonaa taban. Waqtigan, Null point iyo Peak point way isku beddeli doonaan. Q+ point iyo Q- point sidoo kale way isku beddeli doonaan. Polar-ku wuxuu u oggolaanayaa isticmaalaha inuu beddelo polar-ka.
si toos ah iyada oo aan la beddelin goobaha hawlgalka.
2Hal doorasho oo keliya ayaa la dooran doonaa inta u dhaxaysa isticmaalka photodiode-ka koontaroolaha ama isticmaalka modulator photodiode-ka. Waxaa lagu talinayaa in loo isticmaalo photodiode-ka koontaroolaha tijaabooyinka Shaybaarka laba sababood awgood. Marka hore, photodiode-ka koontaroolaha wuxuu hubiyay tayada. Marka labaad, way fududahay in la hagaajiyo xoogga iftiinka la geliyo. Haddii aad isticmaaleyso photodiode-ka gudaha ee modulator-ka, fadlan hubi in hadda soo saarista ee photodiode-ku ay si adag ugu egtahay awoodda la gelinayo.
Rofea Optoelectronics waxay bixisaa khad wax soo saar oo ah modulators-ka ganacsiga ee Electro-optic, modulators-ka wejiga, modulator-ka xoogga, Photodetectors, ilaha iftiinka Laser-ka, laser-ka DFB, Adlamadaha indhaha, EDFA, laser-ka SLD, modulation-ka QPSK, Laser-ka garaaca wadnaha, qalabka digniinta iftiinka, sawir-qaadaha dheelitiran, darawalka Laser-ka, amplifier-ka Fiber optic, mitirka awoodda indhaha, laser-ka Broadband, laser-ka la hagaajin karo, qalabka ogaanshaha indhaha, darawalka diode-ka Laser-ka, qalabka xoojinta fiber-ka. Waxaan sidoo kale bixinnaa modulators gaar ah oo badan oo loogu talagalay habaynta, sida modulators-ka wejiga 1*4, Vpi-ga aadka u hooseeya, iyo modulators-ka saamiga baabi'inta aadka u sarreeya, oo inta badan loo isticmaalo jaamacadaha iyo machadyada.
Waxaan rajeyneynaa in alaabtayadu ay adiga iyo cilmi-baaristaadaba ku anfici doonaan.
