Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
Njengoba singena ku-2026, inselele eyinhloko embonini yezikhungo zedatha akusekho ukwandiswa kwamandla okulula. Esikhundleni salokho, imboni igxile ekusebenziseni kahle yonke i-kilowatt yamandla kanye nemithombo yekhompyutha ukubhekana nokukhula kwebhizinisi okusheshayo, izindleko zokutshalwa kwezimali ezikhulayo, kanye nokusebenza kwengqalasizinda okuyinkimbinkimbi ngokwengeziwe, okubeka isisekelo esiqinile sokwakha izikhungo zedatha zesizukulwane esilandelayo ezisebenza kahle kakhulu nezihlakaniphile.
Ukuthuthukiswa kwe-AI sekuyinto ebalulekile ekuthuthukiseni ingqalasizinda yesikhungo sedatha esishayela injini. Ukwamukelwa okusheshayo kwe-Generative AI kanye namaModeli Olimi Olukhulu (ama-LLM) kudinga amakhono okucubungula ezingeni eliphezulu ukuze kuqeqeshwe amamodeli ayinkimbinkimbi futhi kuhlaziywe amasethi edatha amakhulu. Lokhu kungafezwa kuphela ngokusabalalisa umthwalo womsebenzi kuwo wonke amaqoqo amakhulu eseva ye-GPU axhunyiwe.
Ama-chip e-GPU esimanje asebenzisa amandla asukela ku-700W kuya ku-1200W ngalinye, kanti iseva eyodwa ye-AI enobukhulu obuphezulu ingadlula ukusetshenziswa kwamandla okungu-8 kW. Njengoba ama-GPU ayi-10 efakwe ku-rack eyodwa kuphela, ukusetshenziswa kwamandla kufinyelela kalula ku-80 kW, okuletha izidingo eziphakeme zokuphakelwa kwamandla esikhungo sedatha, ukupholisa, ukuxhumanisa izintambo kanye nezinhlelo zokudlulisa inethiwekhi.
Ubukhulu bamaqoqo okuqeqesha i-AI bukhula ngesivinini esingavamile, bushintsha kusukela kumaqoqo okuqala ayi-10,000 e-GPU kuya kumakhulu ezinkulungwane noma ngisho nezigidi zokufakwa kwe-GPU. I-Oracle ihlela ukuqalisa ukuthunyelwa kokuqala kwama-GPU angu-50,000 ezinsizakalo ze-AI kusukela ngo-2026, kuyilapho izinkampani ezinkulu embonini zihlose ama-GPU afinyelela ezigidini ezingu-50 eminyakeni emihlanu ezayo, okwandisa kakhulu isidingo sokuxhuma amakhebula amakhulu kanye nokuxhumeka okusheshayo.
Iqhutshwa izidingo zokuxhumeka okusheshayo, isivinini senethiwekhi kuzo zonke izendlalelo zesikhungo sedatha sidlula ekuphindaphindweni okubanzi. Ukuxhumeka kwe-Backend GPU-to-GPU kuya ku-1.6T kuya ku-3.2T, kuyilapho izixhumanisi ze-inter-cluster ziguqukela ku-3.2T. Ukuxhumeka kwe-frontend switch-to-switch kuyathuthukiswa kusuka ku-400G/800G kuya ku-1.6T, kanti izixhumanisi zokufinyelela kuseva ziyathuthukiswa kusuka ku-100G/200G kuya ku-400G, zisekela ngokugcwele ukuqeqeshwa kwemodeli ye-AI, ukuhlaziywa kwedatha yesikhathi sangempela kanye nokusebenza kwesicelo samafu.
Ukuze kuhlangatshezwane nalokhu kuthuthukiswa okusheshayo kakhulu, i-high-bandwidth Direct Attach Copper (DAC) kanye ne-Active Optical Cables (AOC) seziyizixazululo eziyinhloko zokuxhumeka kwe-GPU okuqondile. Izixazululo ze-optical ze-multi-fiber parallel single-mode optical ezingabizi kakhulu ezilahlekelwa yizindleko zisetshenziswa kabanzi ekufakweni kwezintambo okuhlelekile phakathi kwamaswishi namaseva.
Njengamanje, imboni isebenzisa kabanzi amazinga omzila angu-100 Gb/s ukusekela imicu engu-400G engaphezu kwengu-8 kanye nemicu engu-800G engaphezu kwengu-16. Njengoba izinga elizayo le-IEEE 802.3dj kulindeleke ukuthi likhishwe maphakathi no-2026, amazinga omzila angu-200 Gb/s azovumela imicu engu-800G engaphezu kwengu-8 kanye nemicu engu-1.6T engaphezu kwengu-16. Uma sibheka phambili, ubuchwepheshe bezinga lomzila ongu-400 Gb/s sebuvele buthuthukiswa, obuzosekela imicu engu-1.6T ngaphezu kwengu-8 kanye nemicu engu-3.2T ngaphezu kwengu-16, okuqinisa kakhulu ukwakheka kokudluliselwa kwesikhungo sedatha esisheshayo esizayo.
Njengomhlinzeki ochwepheshe wezixazululo zokuxhumana kwe-optical kanye ne-data center cable, i-Kexint ilandela eduze izitayela ze-data center zomhlaba wonke, iqhubeka nokuthuthukisa imikhiqizo yokudlulisa i-optical esheshayo kanye nezixazululo ze-cable ezilungiselelwe, futhi inikeza ukwesekwa kwengqalasizinda okuthembekile nokusebenza kahle kakhulu kwe-data center yomhlaba wonke kanye ne-cloud computing.
