Te ōwehenga mōrahi o te whakangaromanga DC
I tēnei whakamātautau, kāore he tohu RF i whakamahia ki te pūnaha. Kua inehia te tineitanga DC parakore.
1. E whakaatu ana te Pikitia 5 i te mana whatu o te putanga o te modulator, i te wā e whakahaerehia ana te modulator i te tihi. E whakaatu ana i te 3.71dBm i roto i te hoahoa.
2. E whakaatu ana te Pikitia 6 i te mana whatu o te putanga o te modulator, i te wā e whakahaerehia ana te modulator i te pūwāhi Kore. E whakaatu ana i te -46.73dBm i roto i te hoahoa. I roto i te whakamātautau tūturu, ka rerekē te uara i te -47dBm; ā, he uara pumau te -46.73.
3. Nō reira, ko te ōwehenga o te ngaromanga DC pumau i inehia he 50.4dB.
Ngā whakaritenga mō te ōwehenga ngaro teitei
1. Me teitei te ōwehenga whakamōmona o te kaiwhakatikatika pūnaha. Ko te āhuatanga o te kaiwhakatikatika pūnaha e whakatau ana i te ōwehenga whakamōmona mōrahi ka taea te whakatutuki.
2. Me āta tiaki te whakapōratanga o te mārama whakauru o te modulator. He tairongo ngā modulator ki te whakapōratanga. Ka taea e te whakapōratanga tika te whakapai ake i te ōwehenga mate neke atu i te 10dB. I roto i ngā whakamātautau taiwhanga, me whakamahi i te kaiwhakahaere whakapōratanga.
3. Ngā kaiwhakahaere pāhekoheko tika. I roto i tā mātou whakamātautau ōwehenga whakamōmona DC, kua tutuki te ōwehenga whakamōmona 50.4dB. Ahakoa ko te pepa raraunga o te kaihanga pūwhakarerekētanga anake e whakarārangi ana i te 40dB. Ko te take o tēnei whakapainga he tere rawa te nekeneke o ētahi pūwhakarerekētanga. Ka whakahoutia e ngā kaiwhakahaere pāhekoheko Rofea R-BC-ANY te ngaohiko pāhekoheko i ia hēkona 1 kia tere ai te urupare.

1. Ko te MER e pā ana ki te Ōwehenga Whakangaromanga Modulator. Ko te ōwehenga whakangaromanga e tutukihia ana ko te ōwehenga whakangaromanga o te modulator kua tohua i roto i te pepa raraunga modulator.
2. Ko te CSO e pā ana ki te raupapa tuarua whakahiato. Hei ine tika i te CSO, me whakarite te kounga raina o te tohu RF, ngā modulators me ngā kaiwhiwhi. Hei tāpiri, ka rerekē pea ngā pānui CSO pūnaha ina whakahaerehia i ngā auau RF rerekē.
3. Kia mōhio mai, kāore te mana whatu whakauru e ōrite ki te mana whatu i te pūwāhi piro kua tohua. E pā ana tēnei ki te mana whatu mōrahi ka taea e te modulator te kaweake ki te kaiwhakahaere ina kei waenga i te ngaohiko piro te −Vπ ki te +Vπ.

1. He photodiode ā-roto kei ētahi o ngā modulator MZ. Me whiriwhiri te whakatakotoranga o te kaiwhakahaere i waenga i te whakamahi i te photodiode a te kaiwhakahaere, te whakamahi rānei i te photodiode ā-roto o te modulator. E rua ngā take e taunakihia ana kia whakamahia te photodiode a te kaiwhakahaere mō ngā whakamātautau taiwhanga. Tuatahi, kua whakapūmauhia te kounga o te photodiode a te kaiwhakahaere. Tuarua, he māmā ake te whakarite i te kaha o te mārama whakauru. Kia mahara: Ki te whakamahi koe i te photodiode ā-roto o te modulator, me whakarite kia tino ōrite te ia putanga o te photodiode ki te mana whakauru.
2. Ka whakamahia te pine pōro hei whakawhiti i te pūwāhi whakahaere i waenga i te Piki me te Kore i te aratau whakahaere Kore (ka whakatauhia e te pine Kōwhiri Aratau) Quad+ rānei
me te Tapawhā- i roto i te aratau whakahaere Tapawhā. Mēnā kāore te peke o te pine polar i whakaurua, ka Kore te pūwāhi whakahaere i roto i te aratau Kore, Tapawhā+ rānei i roto i te aratau Tapawhā. Ka pāngia hoki te pūwāhi whakahaere e te whānuitanga o te pūnaha RF. Mēnā kāore he tohu RF, he iti rānei te whānuitanga o te tohu RF, ka taea e te kaiwhakahaere te raka i te pūwāhi mahi ki te pūwāhi tika i tohua e te peke MS me te PLR. Mēnā ka nui ake te whānuitanga o te tohu RF i tētahi paepae, ka rerekē te polar o te pūnaha, i tēnei wā, me noho te pane PLR ki te āhua rerekē, arā, me whakauru te peke mēnā kāore, me unuhia rānei mēnā kua whakaurua.
Te Whakamahinga Noa
He ngāwari te whakamahi i te kaiwhakahaere.
Hipanga 1. Honoa te tauranga 1% o te hononga ki te photodiode o te kaiwhakahaere.
Hipanga 2. Honoa te putanga ngaohiko rītaha o te kaiwhakahaere (mā te SMA, mā te pane 2-pine 2.54mm rānei) ki te tauranga rītaha o te modulator.
Hipanga 3. Hoatu ki te kaiwhakahaere ngā ngaohiko DC +15V me te -15V.
Hipanga 4. Tautuhi anō i te kaiwhakahaere, ā, ka tīmata te mahi.
TŪHIRO. Kia tino mohio kei te kā te tohu RF o te pūnaha katoa i mua i te tautuhi anō i te kaiwhakahaere.
