Pūmauwhakawhitiwhiti kōrero whatu: te wāhanga o te māramatanga
Ko te whakawhitiwhiti kōrero ōrite ehara i te mea ko te kanapa o te mārama anake, engari ko te wāhi kei reira te āhua o te mārama, ā, e rua ngā whakapolarisasi orthogonal e whakamahia ana. Mā tēnei, ka taea te utaina he nui ake ngā mōhiohio ki te roanga ngaru kotahi, ā, ka taea hoki te tawhiti atu i te tawhiti tuku.
1, Pūtake māramatanga ōrite: he taiaho tonu, engari me nui ake te pumau
Ko te pūtake mārama i roto i te whakawhitiwhiti kōrero mārama he rēhia tonu CW. Ehara i te rēhia pāorooro, i te LED rānei, engari he putanga tonu o te hihi mārama pumau hei ngaru kawe mō te whakarerekētanga i muri mai. Ki te whakataurite ki te CWpūtake māramaI roto i ngā kōwae whatu poto noa, me nui ake ngā whakaritenga. Ehara i te mea ko te rawaka o te mana anake te mea nui, engari me pumau hoki te auau me te iti o te haruru ā-wāhanga. Nō reira, ka taea te mārama ki ngā pūtake mārama honohono hei 'tohutoro whatu' pumau ake. He reera tonu tonu, engari me teitei ake te pumau.
2, Te whakarerekētanga ōrite: Kāore i te rite ki te whakarerekētanga o te EML
Ko te hanganga o te EMLReera DFB+EAM electroabsorbent modulator. Ko te EAM te kawenga mō te whakarerekē i te kaha mimiti kia mārama ake, kia pōuri ake rānei te mārama putanga. Nō reira, ko te modulator i roto i te EML te nuinga o te wā e mahi ana i te kaha o te whakarerekētanga. He rerekē te taunga ōrite. I te nuinga o te wā ka whakamahiaKaiwhakarerekē IQKāore ngā pūwhakatikatika IQ e whakakanapa noa i te mārama, e whakapōuri rānei, engari e wehewehe ana i te hihi mārama tonu ki ngā ara I me Q, e whakahaere ana i ngā wāhanga āhuahanga orthogonal e rua e 90 nekehanga te wehe, kātahi ka hanga i te putanga. Mā tēnei, ka taea e te mārama putanga te kawe i ngā mōhiohio whānui me te āhuahanga i te wā kotahi.
3, Te whakahekenga ōrite: te whakamahi i te rama oscillator ā-rohe hei pānui i te wāhanga
Ka taea e te PD noa te kite i te kaha o te mārama anake, ā, kāore e taea te kite tika i te āhua. Hei pānui i te āhua i roto i te whiwhinga mārama, me whakauru he hihi tohutoro e kiia nei ko te LO, te taiaho oscillator ā-rohe. Ka tukuna e te pito whiwhi te mārama tohu kua tukuna me te mārama oscillator ā-rohe ki roto i te mīhini whakaranu whatu. E rua ngā hihi mārama ka pokanoa, ā, ko te hua o te pokanoa e pā ana ki te rerekētanga āhua i waenganui i a rāua. Muri iho, ka hurihia e te pūoko taurite tēnei hua pokanoa hei tohu hiko. Mā te mārama oscillator ā-rohe, ka taea e te pito whiwhi te whakatau i te koki o te wehenga o tēnei mārama tohu e pā ana ki te mārama tohutoro.
4、 Tauwāhi i AIDC: Ko te tawhiti poto e titiro tonu ana ki te IM-DD, ko te DCI e titiro ake ana ki te ōritetanga
Ko te wāhi tino mārama mō te whakawhitiwhiti kōrero ōrite i roto i ngā pokapū raraunga AI ko DCI, arā, ko te Data Center Interconnection. Arā, ko ngā hononga tere-teitei i waenga i ngā pokapū raraunga, ngā pāka, me roto i ngā tāone nui.
Heoi anō, kei a IM-DD tonu ngā painga utu me te mana i roto i ngā hononga tawhiti-poto i roto me waenga i ngā kāpata. Ka whakamahia tonutia e ngā kōwae whatu tawhiti-poto 800G me 1.6T te ara kotahi me te EML, ngā whatu silicon, PAM4, PD, me te TIA. He nui ake ngā wāhanga o te pūnaha honohono, he nui ake te whakamahinga mana, he taumaha ake hoki te DSP, ā, e kore e whakakapia noatia ngā kōwae whatu tawhiti-poto.
