Nco tseg:
1 * Hais txog lub zog hluav taws xob ntau cov qauv rau tus qauv thaum cov khoom tsim tawm modulator yog qhov siab tshaj plaws. Rau qhov tsis tshua muaj kev tswj hwm ntawm tus modulator nrog lub siab extinction piv, lub hwj chim tawm yuav tsum tau nce ntxiv; Nrog tshwj xeeb lub zog cov tswv yim yuav tsum tau, koj tuaj yeem kho cov ntsuas txuas sab hauv thiab kuaj pom cov ntsuas pom tau, thov kev sab laj muag thaum tso cov xaj.
2 * Thaum tso ib qho kev txiav txim, thov qhia cov nthwv dej ua haujlwm, uas yuav tsum tau ua kom zoo raws li lub wavelength.
3 * Hloov Exquinction Piv txwv tseem nyob ntawm tus hloov pauv kev sib piv ntawm qib ntawm modulator nws tus kheej.

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, Null Point thiab Peak point yuav hloov pauv nrog txhua lwm.Q • Taw tes thiab q-point yuav hloov pauv nrog txhua lwm yam li cov neeg siv nyiaj polar
ncaj qha tsis tau hloov cov ntsiab lus ua haujlwm.
2Tsuas yog ib qho kev xaiv yuav raug xaiv ntawm kev siv maub los lub photodiode 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 los kho lub tswv yim teeb siv.ci siv cov khoom siv sab hauv sab hauv
Rofea Optoelectronics muaj cov kab khoom lag luam electro-lub teeb ntes, ntsuas hluav taws xob, ntsuas hluav taws xob, dav hlau laser, dav dav 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.
