Maxim DC excintion piv
Hauv qhov kev sim no, tsis muaj RF cim tau raug thov rau lub kaw lus. Ntshiab DC excstinciton tau ntsuas.
1. Daim Duab 5 Ua rau pom lub zog kho qhov muag ntawm cov qauv hloov kho, thaum modulator tswj ntawm lub ntsiab lus peak. Nws qhia 3.71dbm hauv daim duab.
2. Daim duab 6 qhia txog lub zog ntawm cov khoom siv kho qhov muag, thaum modulator tswj ntawm NULLATE PART. Nws qhia -46.73DBM hauv daim duab. Hauv kev sim tiag tiag, tus nqi sib txawv nyob ib ncig ntawm -47DBM; thiab -46.73 yog tus nqi ruaj khov.
3. Yog li ntawd, qhov ruaj khov DC extinction ntsuas yog 50.4dB.
Yuav tsum muaj rau cov piv txwv tseem ceeb
1. Cov txheej txheem Modulator yuav tsum muaj cov piv txwv txiav txim siab. Cov yam ntxwv ntawm cov kab ke kev txiav txim siab qhov kev sib piv siab tshaj plaws tau ua tiav.
2. Polarization ntawm Modulator tawm tswv yim lub teeb yuav tsum tau saib xyuas. Modulators yog nkag siab txog kev sib tw. Raws li kev ua kom raug cai tau zoo tuaj yeem txhim kho kev tshem tawm tas li 10dB. Hauv kev sim ua haujlwm lab, feem ntau yog tus kws sau tshuaj polarization yog xav tau.
3. Tsim nyog cov neeg muaj tswv yim tsis zoo. Hauv peb DC excinction sib piv, 50.4db extinction ratio tau tiav lawm. Thaum lub datasheet ntawm modulator siv xwb tsuas yog teev 40dB. Qhov laj thawj ntawm txoj kev txhim kho no yog tias qee cov modulators drift heev. Rofile R-BC-TXHUA YAM KEV TXHAJ TSHUAJ HLOOV LUB BIAS TXHUA Voltage Txhua 1 Thib Ob Los Xyuas Kom Muaj Kev Teb Rov Qab Los.

1. Qee qhov MZ modulators muaj cov photodes sab hauv. Cov teeb tsa teeb tsa yuav tsum tau xaiv ntawm kev siv maub los lub photodiode lossis siv modulator lub photodiode sab hauv. Nws raug nquahu kom siv maub los lub photodiode rau cov kev sim sim rau ob qho laj thawj. Firstly, tswj hwm photodiode muaj ensured zoo. Thib ob, nws yog qhov yooj yim dua los kho lub kaw lub teeb intentsity. NCO TSEG: Yog tias siv Modulator lub PhotoDiode, thov nco ntsoov tias cov zis tam sim no ntawm photodiode yog nruj me ntsis proportional kom pom lub zog tawm.
2.
thiab quad- hauv quad tswj hom. Yog tias jumper ntawm polar pin tsis tau ntxig, tswj hwm yuav tsis yog thov hauv hom tsis yog los yog qev + hauv Quad hom. Qhov ntawm RF system tseem yuav cuam tshuam rau kev tswj hwm qhov chaw. Thaum tsis muaj lub teeb liab RF lossis RF teeb liab nthuav dav yog me, maub los muaj peev xwm kaw qhov haujlwm taw tes rau kev xaiv los ntawm MS thiab plr jumper. Thaum RF teeb liab ntau dua li qhov pib pib, Polar ntawm lub xeev, piv txwv li cov jumper yuav tsum tau ntxig yog tias nws tau tso.
Raug Thov
Tus maub los yog yooj yim siv.
Ruam1. Txuas 1% chaw nres nkoj ntawm lub coupler rau lub thawv ntawm tus maub los.
