I-1. I-PERP ibhekisa kwimodyuli yemodyuli. Umyinge wokuphela kokuphela ufezekisiwe ngokuqhelekileyo i-scution yemodyuli echazwe kwi-modlilator Dayesheet.
2. Nceda uqaphele ukuba amandla aphethwe ngamandla akahambelani namandla aphesheya kwindawo ekhethiweyo ye-bias. Ibhekisa kumandla aphezulu awodwa aphelela umnqophiso anokuthumela ngaphandle ukuba alawule xa uquka biis biltage ukusuka kwi-Vππ kuye.

I-1 polalar ixhomekeke kwinkqubo ye-RF ye-RF. Xa kungekho nto ingekhoyo kwi-RF kwinkqubo, i-polar kufuneka ibe nethemba. Xa i-RF uphawu lune-ampling likhulu kunenqanaba elithile, i-polala iya kutshintsha ukusuka kwinto engalunganga. Ngeli xesha, indawo ye-null kunye nenqanaba lencopho liya kutshintshela nganye.Q + inqaku kwaye i-qport kunye ne-qa itshintshe kunye ne-Instar .Pola itshintshe i-polar
ngqo ngaphandle kokutshintsha kwamanqaku okusebenza.
2Kukhetho olunye kuphela oluya kukhethwa phakathi kokusebenzisa i-piefdiode okanye usebenzisa i-modlilator Photodiode. Kucetyiswa ukuba usebenzise i-Photoler Okokuqala, i-pitlerdiode iqinisekisile iimpawu. Okwesibini, kulula ukuhlengahlengisa amandla okukhanya okukokwabisa.Ukusebenzisa i-modlilatode yemodyuli yemodyuli, nceda uqiniseke ukuba iziphumo zangoku ze-Photodiode zilungelelaniswe ngokukuko.
I-rofea aptoelection ibonelela ngemveliso yemveliso ye-electro-optic, iimodyuli zesigaba, i-fotose, i-ampleeper, i-pids, i-qpber, i-qpber, i-fiber optic, ibhendi yamandla e-fiber I-Laser, i-Tuncay Laser, i-piolical piode umqhubi, i-fiber amplifier. Sikwabonelela ngeemodyuli ezininzi zokwenza ngokwezifiso, ezinje nge-1 * 4 Imodyuli yesigaba se-Ultra, ephantsi i-Ultra-I-VPI, kunye ne-Ultra-Speeliction Prilators Imodyuli, ngokuyintloko isetyenziswa kwiiyunivesithi nakumaziko.
Ndiyathemba ukuba iimveliso zethu ziya kuba luncedo kuwe kunye nophando lwakho.
