Me pēhea te whakamahi i teKaiwhakarerekē EO

I muri i te whiwhinga i te EO modulator me te whakatuwheratanga i te kete, me mau ngā karapu/rīpene hikohiko ina pā atu koe ki te anga ngongo whakarewa o te taputapu. Whakamahia he tweezers hei tango i ngā putanga whakauru/putanga whatu o te taputapu mai i ngā awaawa o te pouaka, kātahi ka tango i te tinana matua o te modulator mai i ngā awaawa hautai. Kātahi ka pupuri i te tinana matua o te EO modulator ki te ringa kotahi ka tōia te putanga whakauru/putanga whatu o te modulator ki te ringa kē.

Te whakarite me te tirotiro i mua i te whakamahinga

a. Tirohia mēnā kāore he kino ki te mata o te hua, te mata o te kōwae me te ringaringa muka whatu.

b. Tirohia mēnā he paru te tapanga, ā, he mārama hoki ngā tohu o te tānga mata hiraka.

c. Kāore te flange hiko i pakaru, ā, kei te ora tonu ngā pine hiko katoa.

d. Whakamahia he taputapu kite mata o te muka whatu hei tirotiro mēnā he ma ngā muka whatu i ngā pito e rua.

1. Ngā taahiraa mō te whakamahite whakarerekētanga kaha

a. Tirohia mēnā he ma ngā pito o ngā muka whatu whakauru/putanga o te intensity modulator. Mēnā he paru, horoia ki te waipiro.

b. He tāuru pupuri-polarization te whakarerekētanga kaha. E taunakihia ana kia whakamahia he pūtake mārama pupuri-polarization ina whakamahia ana (ko te roangaru o te pūtake mārama e whakawhirinaki ana ki te roangaru e tika ana o te whakarerekētanga), ā, ko te mana mārama o te pūtake mārama he 10dBm te pai.

I te wā e whakamahia ana te pūwhakatikatika kaha, honoa te pūtake hiko GND ki te pine 1 o te pūwhakatikatika, me te pito pai o te pūtake hiko ki te pine 2. Ko te pine 3/4 te katote me te anote o te PD i roto i te pūwhakatikatika. Mena me whakamahi koe, whakamahia tēnei PD me te ara iahiko hopu i te pito o muri, ā, ka taea te whakamahi i tēnei PD me te kore e pā te ngaohiko (ki te kore he PD o roto o te pūwhakatikatika, ko te pine 3/4 he NC, he pine iri).

d. Ko te rauemi o te pūwhakatikatika kaha he lithium niobate. Ina whakamahia he papa hiko, ka rerekē te taupū whakaata o te tioata. Nō reira, ina whakamahia he ngaohiko ki te pūwhakatikatika, ka rerekē te ngaronga whakaurunga o te pūwhakatikatika me te ngaohiko e whakamahia ana. Ka taea e ngā kaiwhakamahi te whakahaere i te pūwhakatikatika i tētahi pūwāhi mahi e ai ki tā rātou whakamahinga.

Ngā Whakatūpato

a. Kaua te tāuru whatu o te pūwhakamātautau e neke ake i te uara whakataurite kei runga i te pepa whakamātautau; ki te kore, ka pakaru te pūwhakamātautau.

b. Kaua te tāuru RF o te pūwhakawhitiwhiti e neke ake i te uara kua whakaritea i runga i te pepa whakamātautau; ki te kore, ka pakaru te pūwhakawhitiwhiti.

c. Ko te ngaohiko tāpiri o te pine ngaohiko whakahāngai whakarerekētanga he ≤±15V

2. Ngā taahiraa mō te whakamahi i tekaiwhakarerekētanga wāhanga

a. Tirohia mēnā he ma ngā pito o ngā muka whatu whakauru/putanga o te intensity modulator. Mēnā he paru, horoia ki te waipiro.

b. He tāuru pupuri-polarization te modulator ā-wāhanga. E taunakihia ana kia whakamahia he pūtake mārama pupuri-polarization ina whakamahia ana (ko te roangaru o te pūtake mārama e whakawhirinaki ana ki te roangaru e tika ana o te modulator), ā, ko te mana mārama o te pūtake mārama he 10dBm te pai.

c. Ina whakamahia he pūwhakarerekētanga ā-wāhanga, honoa te tohu RF ki te tauranga whakauru RF o te pūwhakarerekētanga.

d. Ka taea e te kaiwhakatikatika ā-wāhanga te mahi i muri i te tāpiri i te tohu auau reo irirangi, hei whakaoti i te ā-wāhangakaiwhakarerekē hiko-whatuKāore e taea te kite tika i te mārama kua whakarerekētia e te pūoko whakaahua hei tohu auau reo irirangi kua whakarerekētia. I te nuinga o te wā, me whakarite he ine whakawhiti, ā, ka taea anake te kite i te tohu auau reo irirangi e te pūoko whakaahua i muri i te pokanoa.

Ngā Whakatūpato

a. Kaua te tāuru whatu o te pūwhakatikatika EO e neke ake i te uara whakatikatika kei runga i te pepa whakamātautau; ki te kore, ka pakaru te pūwhakatikatika.

b. Kaua te tāuru RF o te pūwhakatikatika EO e neke ake i te uara kua whakaritea i runga i te pepa whakamātautau; ki te kore, ka pakaru te pūwhakatikatika.

c. I te wā e whakatū ana i tētahi ine whakawhiti, he nui ngā whakaritenga mō te taiao whakamahinga. Ka pā pea te wiri o te taiao me te nekeneke o te muka whatu ki ngā hua o te whakamātautau.
