I tēnei wā, ko ngā kōwae IO o SFP28/SFP56 me QSFP28/QSFP56 e whakamahia ana hei hono i ngā pana me ngā pana me ngā tūmau i roto i ngā kāpata matua o te mākete. I te tau o te tere 56Gbps, kia whai ai i te kiato tauranga teitei ake, kua whakawhanakehia e te tangata te kōwae IO QSFP-DD kia tutuki ai te kaha tauranga 400G. Nā te rua o te tere tohu, kua rua te kaha tauranga o te kōwae QSFP DD ki te 800G, e kiia nei ko OSFP112. E waru ngā hongere tere-teitei kua tākaihia, ā, ka taea e te tere tuku o te hongere kotahi te eke ki te 112G PAM4. Ko te tere tuku katoa o te mōkihi katoa tae atu ki te 800G. Ki te whakatauritea ki te wā kotahi, ka rua te tere, ka tutuki i te paerewa hononga IEEE 802.3CK; Nō reira, ka piki ake te ngaronga hononga, ā, ka poto ake te tawhiti tuku o te kōwae IO CABLE parahi kore mahi. I runga i ngā here ā-tinana tūturu, i whakaitihia e te tīma IEEE 802.3CK, nāna i tito te whakatakotoranga 112G, te roa mōrahi o te hononga taura parahi ki te 2 mita i runga i te kaupapa o te taura parahi 56G IO me te tere mōrahi o te 3 mita.
Papa whakamātautau QSFP-DD X 2 tauranga 1.6Tbps
Ka tū pakari a QQSFP -DD 800G ki te hau
Ko ngā āheinga o te pokapū raraunga ka whakatauhia e ngā tūmau, ngā pana, me ngā āhuatanga hononga e taurite ana tetahi ki tetahi, e pana ana tetahi ki tetahi ki te tipu tere ake, iti iho te utu. Ko te hangarau whakawhiti te kaha matua mō ngā tau maha. I te mutunga o te OFC2021 i ēnei rā tata nei, kua whakaatuhia e ngā kaihanga whakawhitiwhiti kōrero whatu matua pērā i a Intel, Finisar, Xechuang, Opticexpress me New Yisheng ngā kōwae whatu raupapa 800G. I taua wā anō, i whakaatuhia e ngā kamupene maramara whatu o tāwāhi ngā hua maramara teitei mō te 800G, ā, tera pea kei te whai wāhi tonu te kaupapa tuku iho i te wā 800G. Ki tā mātou whakaaro kua mārama haere te ara hangarau kōwae whatu 800G, ko te 800GDR8 me te 2*FR4 ngā mea tino kaha; I te mea kua whakarewahia e ngā kamupene kōwae whatu matua me ngā maramara whatu matua o OFC2021 ngā hua hou tetahi i muri i tetahi, kua tautuhia te pona wā me te ara hangarau matua o te whakapai ake i te 800G. Kei te haere tonu te tere o te umanga kōwae whatu pokapū raraunga, ā, kua whakatauhia te āhuatanga tipu mo te wā roa. E whakapono ana mātou i tēnei wā o te mamati me te mātauranga, nā te pikinga tonu o te maha o ngā raraunga kua puta, kua piki ake te hiahia mō te whakahou tonu i ngā waeine whatu. Ko te huarahi hangarau mārama o te 800G e tohu ana ka nui te horapa o te 400G.
Ina whakahoutia te tere tohu 25Gbps ki te tere tohu 56Gbps o nāianei, nā te whakaurunga o te pūnaha tohu PAM4 (Pulse Amplitude Modulation) (rōpū IEEE 802.3BS), ka neke noa te pūwāhi auau taketake o te tohu e tukuna ana i runga i te hononga Serdes Ethernet mai i te 12.89ghz ki te 13.28ghz, ā, kāore te pūwāhi auau taketake o te tohu e tino rerekē. Ka taea te whakahou i ngā pūnaha ka taea te tautoko i te tuku pai o ngā tohu 25Gbps ki ngā tere tohu 56Gbps me te iti o te arotautanga. Ehara i te mea ngāwari te whakahou mai i te tere tohu 56Gbps ki te tere tohu 112Gbps. Ko te pūnaha tohu PAM4 i whakauruhia i te wā i whakawhanakehia ai te paerewa tere 56Gbps ka whakamahia anō pea i ngā tere 112Gbps. Ka hurihia e tēnei te pūwāhi auau taketake o te tohu Ethernet 112Gbps ki te 26.56ghz, he rua te nui o te tere tohu 56Gbps. I te whakaputanga o te tere 112Gbps, ka pa ki ngā whakaritenga hangarau taura he whakamātautau uaua ake. I tēnei wā, kei te honoa te taura tere-teitei 400Gbps ki te hua. Ko ngā waitohu tawhito kua tino pakari ko ngā waitohu o tāwāhi, pērā i a TE, LEONI, MOLEX, Amphenol, me ētahi atu. Kua tīmata hoki ngā waitohu o te rohe ki te eke ki runga i ngā tau tata nei. Mai i te tukanga hanga, ngā taputapu me ngā rauemi, he maha ngā auahatanga kua mahia e mātou. I tēnei wā, kei reira ngā umanga o te rohe e hanga ana i te taura parahi 800G, engari kāore i nui te mea i kohia e mātou. Shenzhen Hongteda, Dongguan Zhongyou Electronics, Dongguan Jinxinuo, Shenzhen Simic Communication, me ētahi atu, engari ko te uauatanga hangarau o nāianei kei te wāhanga waea tahanga. I tēnei wā, he tino uaua ki te whakaoti i ngā tawhā mahi hiko auau teitei me ngā whakaritenga ngohengohe o te waea taura i te wā kotahi. Ka tere te whanaketanga o te taura parahi DAC. He iti noa ngā kaihanga waea o te rohe.
Kei te tere te huri o te mākete, ā, ka tere ake te whanake i ngā rā kei te heke mai. Ko te rongo pai, kua puta he ahunga whakamua nui, whai hua hoki, mai i ngā whakahaere paerewa ki te umanga, kia taea ai e ngā pokapū raraunga te neke ki te 400GB me te 800GB. Engari ko te tango i ngā arai hangarau he haurua noa iho o te wero. Ko te haurua kē ko te wā. Kia puta he whakatau hē, ka nui ake te utu. Ko te nuinga o te pokapū raraunga ā-rohe o nāianei ko te 100G. I roto i ngā pokapū raraunga 100G kua whakatinanahia, 25% he parahi, 50% he muka maha-aratau, me te 25% he muka kotahi-kōwae. Kāore ēnei tau wā poto i te tino tika, engari ko te pikinga o te hiahia mō te whānui o te hononga, te kaha, me te iti o te whakaroa kei te akiaki i te hekenga ki ngā tere whatunga tere ake. Nō reira, i ia tau, ko te urutau me te oranga o ngā pokapū raraunga kapua nui he whakamātautau. I tēnei wā, kei te waipuke te mākete i te 100GB, me te tumanako ka eke ki te 400GB i te tau e tū mai nei. Ahakoa tēnei, kei te piki haere tonu te rere o ngā raraunga, ka piki haere tonu te pēhanga ki ngā pokapū raraunga, whai muri i te 400G, kua tae mai te QSFP-DD 800G.
