1. MER yog hais txog Modulator Extinction Ratio. Qhov piv txwv extinction uas tau txais feem ntau yog qhov piv txwv extinction ntawm modulator uas tau teev tseg hauv modulator datasheet.
2. Thov nco ntsoov tias lub zog optical input tsis sib xws rau lub zog optical ntawm qhov chaw bias xaiv. Nws yog hais txog lub zog optical siab tshaj plaws uas lub modulator tuaj yeem xa mus rau tus maub los thaum lub zog bias ntau ntawm −Vπ txog + Vπ.

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.
