I tenei whakamatautau, kaore he tohu RF i tukuna ki te punaha. Kua inehia te whakakorenga DC parakore.
1. Ko te Whakaaturanga 5 e whakaatu ana i te mana whatu o te putanga modulator, i te wa e whakahaeretia ana te modulator ki te pito Peak. E whakaatu ana i te 3.71dBm i te hoahoa.
2. Ko te Whakaaturanga 6 e whakaatu ana i te mana whatu o te putanga modulator, i te wa e whakahaerehia ana te modulator i te tohu Null. E whakaatu ana -46.73dBm i te hoahoa. I nga whakamatautau tuturu, he rereke te uara huri noa -47dBm; a -46.73 he uara pumau.
3. No reira, ko te 50.4dB te tauwehenga korenga o te DC.
Nga whakaritenga mo te nui o te matemate
1. Me whai i te ōwehenga matemate teitei o te kaiwhakaraupapa punaha. Ko nga ahuatanga o te punaha modulator ka whakatau i te nui o te mate ka taea te whakatutuki.
2. Me tiaki te polarization o te rama whakauru modulator. He tairongo nga modulators ki te polarization. Ka taea e te polarization tika te whakapai ake i te ōwehenga ngaro i runga i te 10dB. I roto i nga whakamatautau taiwhanga, ko te tikanga ka hiahiatia he kaiwhakahaere polarization.
3. Nga kaiwhakahaere rītaha tika. I roto i ta maatau whakamatautau mo te whakahekenga o DC, kua tutuki te 50.4dB ōwehenga mate. Ahakoa ko te papaaarangi o te hanga modulator e 40dB anake. Ko te take o tenei whakapainga ko etahi o nga modulators e tere haere ana. Rofea R-BC-ANY mana whakahaere rītaha whakahōu i te ngaohiko rītaha ia 1 hēkona kia tere te whakautu.

1. E tohu ana te MER ki te Modulator Extinction Ratio. Ko te ōwehenga mate kua tutuki ko te ōwehenga ngaro o te kaiwhakaraupapa kua tohua i roto i te papaaarangi korero.
2. E tohu ana te CSO ki te raupapa tuarua hiato. Ki te ine tika i te CSO, me whakarite te kounga raina o te tohu RF, nga kaiwhakatikatika me nga kaiwhiwhi. I tua atu, ka rereke pea nga panui CSO i te wa e rere ana i nga iarere RF rereke.
3. Kia mahara ko te mana whatu whakaurunga kaore e rite ki te mana whatu i te waahi rītaha kua tohua. E tohu ana ki te mana whatu morahi ka taea e te kaihurihuri te kaweake ki te kaitahuri ina awhe ngaohiko rītaha mai i −Vπ ki +Vπ .

1. Ko etahi MZ modulators he photodiodes o roto. Me whiriwhiri te tatūnga kaiwhakahaere i waenga i te whakamahi i te photodiode a te kaiwhakahaere, i te whakamahi ranei i te photodiode o roto. E taunaki ana kia whakamahia te photodiode a te kaiwhakahaere mo nga whakamatautau Lab mo nga take e rua. Tuatahi, kua whakapumautia te kounga o te photodiode kaiwhakahaere. Tuarua, he ngawari ake te whakatika i te kaha o te rama whakauru. Tuhipoka: Mena kei te whakamahi i te photodiode o roto o te modulator, me mohio kei te tino rite te naia putanga o te photodiode ki te mana whakauru.
2. Ka whakamahia te titi polar ki te huri i te tohu mana i waenga i te Peak me te Null i roto i te aratau mana Null (kua whakatauhia e te Aratau Tiwhiri titi) ranei Quad+
me te Quad- in Quad mana mode. Ki te kore e whakauruhia te peke o te titi polar, ka noho kore te tohu mana ki te aratau Null, ki te Quad+ ranei ki te aratau Quad. Ko te kaha kaha o te punaha RF ka pa ki te waahi whakahaere. Ki te kore he tohu RF, he iti ranei te kaha kaha o te tohu RF, ka taea e te kaiwhakahaere te maukati i te waahi mahi ki te whakatika i te tohu i tohua e te pekepeke a MS me te PLR. Ka eke te kaha kaha o te tohu RF ki etahi paepae, ka huri te polar o te punaha, i tenei keehi, me noho te pane o te PLR ki te ahua keehe, ara, me whakauru te peke ki te kore, ka toia ki waho mena ka whakauruhia.
