Chithunzi 1. Chonyamulira kuponderezedwa
Chithunzi 2. Pulse Generation
Chithunzi 3. Modulator max mphamvu
Chithunzi 4. Modulator osachepera mphamvu
Chiwerengero cha Maxim DC
Pakuyesa uku, palibe ma siginecha a RF omwe adayikidwa padongosolo.DC extinciton yoyera yayesedwa.
1. Chithunzi cha 5 chikuwonetsa mphamvu ya kuwala yotulutsa modulator, pamene modulator imayendetsedwa pa Peak point.Ikuwonetsa 3.71dBm pachithunzichi.
2. Chithunzi cha 6 chikuwonetsa mphamvu ya kuwala yotulutsa modulator, pamene modulator imayendetsedwa pa Null point.Ikuwonetsa -46.73dBm pazithunzi.Poyesera kwenikweni, mtengo umasiyana mozungulira -47dBm;ndi -46.73 ndi mtengo wokhazikika.
3. Choncho, chiŵerengero chokhazikika cha kutha kwa DC ndi 50.4dB.
Zofunikira pakuwonongeka kwakukulu
1. Makina osinthira makina ayenera kukhala ndi chiwopsezo chambiri.Makhalidwe a makina osinthira amasankha kuti chiŵerengero cha kuzimiririka chikwaniritsidwe.
2. Polarization ya kuwala kolowera modulator iyenera kusamalidwa.Ma modulators amakhudzidwa ndi polarization.Polarization yoyenera imatha kupititsa patsogolo chiwopsezo cha 10dB.Muzoyesa za labu, nthawi zambiri wowongolera polarization amafunikira.
3. Olamulira atsankho oyenera.Pakuyesa kwathu kwa DC extinction ratio, chiŵerengero cha kutha kwa 50.4dB chakwaniritsidwa.Pomwe zidziwitso za makina opanga ma module amangolemba 40dB.Chifukwa cha kusinthaku ndikuti ma modulators ena amasuntha mwachangu kwambiri.Rofea R-BC-ALIYENSE owongolera kukondera amasintha voteji ya tsankho pa sekondi imodzi iliyonse kuti atsimikizire kuyankha mwachangu.

1. MER ikutanthauza Modulator Extinction Ratio.Chiyerekezo cha kuzimiririka chomwe chimapezedwa nthawi zambiri ndi chiwopsezo cha kutha kwa ma module omwe amatchulidwa mu datasheet ya modulator.
2. CSO imanena za gulu lachiwiri.Kuti muyese CSO molondola, mtundu wa mzere wa siginecha ya RF, ma modulators ndi olandila adzatsimikizidwa.Kuphatikiza apo, kuwerengera kwa CSO kwadongosolo kumatha kusiyanasiyana poyendetsa ma frequency osiyanasiyana a RF.
3. Chonde dziwani kuti kuyika kwamphamvu kwa kuwala sikufanana ndi mphamvu ya kuwala pa malo osankhidwa osankhidwa.Zimatanthawuza mphamvu yochuluka ya kuwala yomwe modulator imatha kutumiza kwa wolamulira pamene voteji ya bias imachokera ku −Vπ mpaka + Vπ.
