1 Ncej polar nyob ntawm qhov system RF teeb liab. Thaum tsis muaj teeb liab RF hauv cov kab ke, lub ncov qaumteb yuav tsum yog qhov zoo. Thaum RF teeb liab muaj ntau dua li theem, lub ncov qaumteb qabteb yuav hloov pauv ntawm qhov zoo. Nyob rau lub sijhawm no, tsis yog taw tes thiab lub ncov Peak yuav hloov pauv nrog txhua lwm yam. Q + taw tes thiab q- point yuav hloov pauv nrog txhua lwm yam nkaus. Ncov qaumteb qabteb ua ke siv cov

1 Tsuas muaj ib qho kev xaiv yuav tsum raug xaiv ntawm kev siv maub los lossis siv Modulator photodiode. Nws raug nquahu kom siv maub los photodiode rau kev sim sim rau ob qho laj thawj. Firstly, tswj cov photodiode muaj ua kom muaj txiaj ntsig zoo. Thib ob, nws yooj yim dua rau kev hloov kho lub teeb pom kev. Yog tias siv Modulator lub photodiode sab hauv, thov nco ntsoov tias cov zis tam sim no ntawm photodiode yog nruj me ntsis sib xws rau cov zog tawm tswv yim.
Rofea OptoelectRonics muaj cov kab kev lag luam electro-edrec laser, teeb ntes, teeb tsa lub teeb ntes, laser photodetector, laser tsav tsheb , Fiber ntau amplifier, kho qhov muag hluav taws xob ntsuas, broadband laser, Tunle laser, kuaj kho qhov muag, laser dioder tsav, fiber ntau amplififify. Peb tseem muab ntau cov neeg modulators rau kev hloov kho, xws li 1 * 4 Array theem modulators, thiab ultra-siab extinction piv, feem ntau siv nyob rau hauv cov tsev kawm qib siab thiab lub tsev.
Vam tias peb cov khoom yuav pab tau koj thiab koj cov kev tshawb fawb.
