Te whanaketanga me te ahunga whakamua o te CPOhikohikohangarau tākai tahi
Ehara te tākai-tahi optoelectronic i te hangarau hou, nō te tekau tau atu i 1960 tōna whanaketanga, engari i tēnei wā, he tākai-tahi whakaahua-hiko noa iho.ngā taputapu optoelectronictahi. I te tekau tau atu i 1990, me te aranga ake o tekōwae whakawhitiwhiti kōrero whatuI roto i te umanga, ka tīmata te puta o te takai-tahi whakaahua-hiko. I te pikinga ake o te mana rorohiko me te tono whānui-rahi i tēnei tau, kua nui anō te aro ki te takai-tahi whakaahua-hiko, me ōna peka hangarau e pā ana.
I roto i te whanaketanga o te hangarau, he rerekē ngā āhua o ia wāhanga, mai i te 2.5D CPO e rite ana ki te tono 20/50Tb/s, ki te 2.5D Chiplet CPO e rite ana ki te tono 50/100Tb/s, ā, i te mutunga ka tutuki te 3D CPO e rite ana ki te tere 100Tb/s.
Ko te 2.5D CPO e whakakī ana i tekōwae whatume te maramara pana whatunga i runga i te papa kotahi hei whakapoto i te tawhiti raina me te whakanui ake i te kiato I/O, ā, ka hono tika te 3D CPO i te IC whatu ki te paparanga takawaenga hei whakatutuki i te hononga o te pitch I/O iti iho i te 50um. He tino mārama te whāinga o tōna whanaketanga, arā, kia whakaitihia te tawhiti i waenga i te waeine tahuritanga hiko whakaahua me te maramara pana whatunga kia rite ki te taea.
I tēnei wā, kei te tīmatanga tonu te CPO, ā, kei te haere tonu ngā raruraru pēnei i te iti o te hua me te nui o ngā utu tiaki, ā, he iti noa ngā kaihanga kei te mākete e taea te whakarato katoa i ngā hua e pā ana ki te CPO. Ko Broadcom, Marvell, Intel, me ētahi atu kaitākaro ruarua anake kei a rātou ngā otinga motuhake kei te mākete.
I whakaurua mai e Marvell tētahi pana hangarau CPO 2.5D mā te whakamahi i te tukanga VIA-LAST i te tau kua hipa. Whai muri i te tukatuka i te maramara whatu silicon, ka tukatukahia te TSV me te kaha tukatuka o OSAT, kātahi ka tāpirihia te maramara hurihuri maramara hiko ki te maramara whatu silicon. E 16 ngā kōwae whatu me te maramara whakawhiti Marvell Teralynx7 e honoa ana ki runga i te PCB hei hanga i tētahi pana, ka taea te whakatutuki i te tere whakawhiti o te 12.8Tbps.
I te OFC o tēnei tau, i whakaatu a Broadcom me Marvell i te whakatupuranga hou o ngā maramara pana 51.2Tbps mā te whakamahi i te hangarau tākai-tahi optoelectronic.
Mai i te whakatupuranga hou o ngā taipitopito hangarau CPO a Broadcom, te mōkihi CPO 3D mā te whakapai ake i te tukanga kia eke ki te kiato I/O teitei ake, te kai mana CPO ki te 5.5W/800G, he tino pai te ōwehenga whai hua o te pūngao, he tino pai te mahi. I taua wā anō, kei te pakaru hoki a Broadcom ki te ngaru kotahi o te 200Gbps me te 102.4T CPO.
Kua whakanuia hoki e Cisco tana haumitanga ki te hangarau CPO, ā, i whakaatu i te whakaaturanga hua CPO i te OFC o tēnei tau, e whakaatu ana i tana kohikohinga hangarau CPO me tana tono ki runga i tētahi multiplexer/demultiplexer kua whakauruhia ake. I kī a Cisco ka whakahaerehia e ia he whakatinanatanga whakamātautau o te CPO ki roto i ngā pana 51.2Tb, ā, ka whai ake ko te whakamahinga nui ki roto i ngā huringa pana 102.4Tb.
Kua roa a Intel e whakauru ana i ngā pana e hangai ana ki te CPO, ā, i ngā tau tata nei kua mahi tahi tonu a Intel me Ayar Labs ki te tūhura i ngā otinga hononga tohu whānui teitei kua tākaihia ngātahi, e whakawātea ana i te ara mō te whakaputa papatipu o ngā taputapu tākai-tahi optoelectronic me ngā taputapu hononga whatu.
Ahakoa ko ngā kōwae mono tonu te whiringa tuatahi, ko te whakapainga whānui o te whai huatanga o te pūngao ka taea e te CPO te kawe mai kua kukume mai i te tini o ngā kaihanga. E ai ki a LightCounting, ka tīmata te piki haere o ngā tuku CPO mai i ngā tauranga 800G me te 1.6T, ka tīmata te wātea haere i te taha hokohoko mai i te tau 2024 ki te 2025, ā, ka hanga he rahinga nui mai i te tau 2026 ki te 2027. I taua wā anō, e matapaetia ana e CIR ka eke te moni whiwhi mākete o te tākai katoa hikohiko ki te $5.4 piriona i te tau 2027.
I te tīmatanga o tēnei tau, i kī a TSMC ka mahi tahi rātou me Broadcom, Nvidia me ētahi atu kiritaki nui ki te whakawhanake tahi i te hangarau photonics silicon, ngā wāhanga whatu takai noa CPO me ētahi atu hua hou, te hangarau tukatuka mai i te 45nm ki te 7nm, ā, i kīia ko te haurua tuarua tere o te tau e whai ake nei ka tīmata ki te whakatutuki i te ota nui, 2025 pea ki te tae ki te wāhanga rōrahi.
Hei mara hangarau whakawhitiwhiti e uru ana ki ngā taputapu photonic, ngā ara iahiko whakauru, te takai, te whakatauira me te whakaata, e whakaata ana te hangarau CPO i ngā huringa i puta mai i te whakakotahitanga optoelectronic, ā, he tino whakahē ngā huringa i puta mai i te tuku raraunga. Ahakoa ka kitea noa te whakamahinga o te CPO i roto i ngā pokapū raraunga nui mō te wā roa, me te whānui haere o te mana rorohiko nui me ngā whakaritenga whānui teitei, kua noho te hangarau hiri-tahi photoelectric CPO hei papa pakanga hou.
Ka kitea ko ngā kaihanga e mahi ana i roto i te CPO e whakapono whānuitia ana ko te tau 2025 te pona matua, he pona hoki me te reiti whakawhiti o te 102.4Tbps, ā, ka nui haere ngā ngoikoretanga o ngā kōwae mono. Ahakoa ka puhoi pea te puta mai o ngā tono CPO, ko te tākai-tahi opto-electronic te huarahi anake hei whakatutuki i ngā whatunga tere teitei, whānui teitei me te mana iti.
