Lus Cim:
1 * yog hais txog qhov nkag ntawm lub zog rau lub module thaum lub modulator tso zis siab tshaj plaws. Rau qhov tswj qis ntawm lub modulator nrog qhov sib piv siab, lub zog nkag yuav tsum tau nce ntxiv kom tsim nyog; Nrog rau cov kev xav tau tshwj xeeb ntawm lub zog nkag, koj tuaj yeem kho qhov coupler sab hauv thiab lub tshuab ntes tau qhov ntsuas, thov sab laj nrog cov neeg muag khoom thaum tso cov xaj.
2 * Thaum tso ib qho kev txiav txim, thov qhia meej txog qhov ua haujlwm wavelength, uas yuav tsum tau ua kom zoo raws li qhov ua haujlwm wavelength.
3 * qhov hloov pauv qhov sib piv kuj nyob ntawm qib hloov pauv qhov sib piv ntawm lub modulator nws tus kheej.

1 Polar nyob ntawm lub system RF teeb liab. Thaum tsis muaj RF teeb liab hauv lub system, lub polar yuav tsum yog qhov zoo. Thaum RF teeb liab muaj qhov loj dua ib qib, lub polar yuav hloov ntawm qhov zoo mus rau qhov tsis zoo. Lub sijhawm no, Null point thiab Peak point yuav hloov nrog ib leeg. Q+ point thiab Q-point yuav hloov nrog ib leeg thiab. Polar switch ua rau tus neeg siv hloov lub polar
ncaj qha yam tsis hloov cov ntsiab lus ua haujlwm.
2Tsuas yog ib qho kev xaiv yuav tsum tau xaiv ntawm kev siv lub photodiode tswj lossis siv modulator photodiode. Nws raug pom zoo kom siv lub photodiode tswj rau kev sim hauv chav kuaj vim ob qho laj thawj. Ua ntej, lub photodiode tswj tau ua kom zoo. Qhov thib ob, nws yooj yim dua los kho qhov ci ntsa iab ntawm lub teeb nkag. Yog tias siv lub photodiode sab hauv ntawm modulator, thov xyuas kom meej tias qhov tam sim no ntawm photodiode yog sib npaug rau lub zog nkag.
