Ibhizinisi lobuchwepheshe obuphezulu eligxile ocwaningweni nasekuthuthukisweni kwezokuxhumana kanye nokukhiqizwa kwefiber optical.
I-CPO (I-Co-packaged Optics): "Ifomu Eliphezulu" Lokusebenza Kahle Kakhulu Kwamandla
I-CPO (Co-packaged Optics) ibilokhu ibhekwa yimboni njenge "impendulo yokugcina" yokuxazulula izinkinga zamandla ngesivinini esikhulu. Ifilosofi yayo eyinhloko "ukuphula imingcele" - ukupakisha injini ye-optical kanye ne-switch ASIC chip ku-substrate efanayo.
Lokhu kuhlanganiswa okungokoqobo okwedlulele kuletha izinzuzo ezibalulekile: ibanga lokudlulisa isignali kagesi lifinyezwa kusukela kumashumi amasentimitha kuya ezingeni lamamilimitha, okunciphisa kakhulu ukulahleka kwesignali. Uma kuqhathaniswa namamojula we-optical avamile axhunywayo, izixazululo ze-CPO zinganciphisa ukusetshenziswa kwamandla ngaphezu kuka-50% ngenkathi zinikeza ubuqotho besignali obuhle kakhulu. Iqhutshwa yiziqhwaga ezifana ne-NVIDIA, i-CPO ibonise amandla amakhulu ezimweni zokuxhumeka okuqondile okuphezulu, okungaphakathi kwe-rack kwezakhiwo ze-Scale-up.
Kodwa-ke, "isithende sika-Achilles" se-CPO sisekuguquguqukeni kwaso okuphansi kakhulu. Uma injini ye-optical ihluleka, ivame ukudinga ukushintshwa kwebhodi lokushintsha elibizayo lonke, okuholela ezindleleni zokusebenza ezibizayo kakhulu. Ngaphezu kwalokho, ukuntuleka kwezindinganiso zemboni ezihlangene kanye nezinselele ezinkulu zokushisa kusho ukuthi i-CPO isabhekene nezingqinamba eziningi ekufezeni ukuthunyelwa okukhulu kwezentengiselwano.
I-NPO (I-Near-Packaged Optics): "Indlela Esebenzayo" Yokulinganisela Ukusebenza Nokuguquguquka
Uma i-CPO iyinguquko enkulu, khona-ke i-NPO (Near-Packaged Optics) ingumguquli osebenzayo. Njengesivumelwano phakathi kwamamojula ajwayelekile axhumekayo kanye ne-CPO, i-NPO ihambisa injini ye-optical eduze kwe-switch chip, ifinyeza kakhulu indlela yesignali kagesi futhi ifinyelele ukusetshenziswa kwamandla okuphansi ngo-50% kunamamojula avamile.
Inzuzo enkulu ye-NPO ukuthi igcina ukushintshwa okuzimele kwezingxenye ze-optical. Lo mklamo "owakhelwe ngaphakathi ongaxhunywa" awugcini nje ngokuhlangabezana nezidingo ezinzima zamaqoqo e-AI computing ukuze kusetshenziswe amandla aphansi kanye nokubambezeleka okuphansi kodwa futhi ugwema iphupho elibi lokusebenza lesimo "sokuhluleka okukodwa" se-CPO. Njengamanje, abakhiqizi abaphambili abanjengo-HG Genuine kanye no-Coherent basheshisa ukuqaliswa kobunjiniyela kwezixazululo ze-6.4T NPO, okwenza kube ushintsho olubalulekile kanye nesengezo ngaphambi kokuba i-CPO ivuthwe ngokugcwele.
I-XPO (i-eXtra-dense Pluggable Optics): "Inguquko Yobuningi" Yomzila Ongena Ku-Pluggable
Ngesikhathi nje amamojula e-optical avamile axhunywayo ebonakala sengathi afinyelela imikhawulo yawo ebonakalayo, kwavela i-XPO (eXtra-dense Pluggable Optics), yasungula "ukuhlasela okuphikisayo" okuhle kakhulu ngo-2026, lapho i-Arista namanye amabhizinisi amaningana ekhipha indinganiso ye-XPO, lo mzila waba yindawo ebalulekile embonini ngokushesha.
Emongweni wayo, i-XPO iyinguquko enamandla yokwakheka kwe-plugable. Ngokusebenzisa umklamo we-dual-PCB sandwich liquid cold plate "Belly-to-Belly", iphusha ngempumelelo i-bandwidth ye-single-module iye ku-12.8Tbps, ikhulisa ubuningi be-bandwidth yephaneli cishe izikhathi ezine. Lokhu kusho ukuthi lapho wakha izikhungo zokubala ezihlakaniphile ezinamakhadi ayizinkulungwane ezingamakhulu, ukusebenzisa ikhambi le-XPO kunganciphisa inani lama-switch racks ngo-75%, konge isikhala esikhulu sesikhungo sedatha kanye nezindleko zengqalasizinda.
I-XPO ayigcini nje ngokuthola i-DNA "elula ukuyigcina" enhle kakhulu yamamojula e-optical endabuko kodwa futhi ivumelana kahle nezimo zokubala ezinabantu abaningi ngokusebenzisa umklamo wayo wokupholisa uketshezi. Kubahlinzeki bezinsizakalo zamafu abazisa kakhulu ukuguquguquka kokusebenza kanye nokuzinza, i-XPO ngokungangabazeki iyisisombululo esiwusizo kakhulu esitholakalayo namuhla.
Isiphetho: Ukuhlalisana kanye nokuhlukahluka, Ukwakha Ikusasa Lekhompyutha
Kulo mjaho wezobuchwepheshe wokuxhumana kwe-optical, akukho "onqobayo othatha konke" ngokuphelele.
I-CPO ihlose ubuningi obuphezulu kanye nokusebenza kahle kwamandla ezimweni ze-Scale-up; i-NPO ithola ibhalansi ephelele phakathi kokusebenza kanye nokugcinwa kwayo; kuyilapho i-XPO, ngokusebenzisa ukusungula izinto ezintsha kwezakhiwo, iphefumulela impilo entsha ezixazululweni zendabuko ezingaxhunywa enkathini ye-AI. Eminyakeni emi-3 kuya kwemi-5 ezayo, lobu buchwepheshe obuthathu buzoveza iphethini yokuvela okunezingqimba kanye nokuhlala ndawonye kobuchwepheshe obuningi.
Kuhlelo lokuhlinzeka ngokuxhumana kwe-optical, lesi yisikhathi esihle kakhulu. Kusukela ekuthuthukisweni kwezinto ezibonakalayo kuma-fiber angenalutho kuya ekuthuthukisweni kokupakisha ku-CPO, NPO, kanye ne-XPO, sisebenzisa imithambo yejubane lokukhanya ukwakha ibhuloho eliqinile kakhulu lamaphupho e-AI esintu. Kulolu hambo lokujaha ukukhanya, kuphela ngokwamukela ukuhlukahluka nokuphishekela ukusungula izinto ezintsha okuqhubekayo lapho singahamba khona kahle futhi siye kude.
