Kugeza ubu, moderi ya IO ya SFP28 / SFP56 na QSFP28 / QSFP56 ikoreshwa cyane cyane muguhuza sisitemu na switch na seriveri mumabati rusange yisoko.Mugihe cyimyaka 56Gbps, kugirango bakurikirane ubwinshi bwicyambu, abantu barushijeho guteza imbere module ya QSFP-DD IO kugirango bagere ku cyambu cya 400G.Hamwe no gukuba kabiri igipimo cyibimenyetso, ubushobozi bwicyambu cya moderi ya QSFP DD bwikubye kabiri kugeza 800G, bwitwa OSFP112.Yapakishijwe imiyoboro umunani yihuta, kandi umuvuduko wo kohereza umuyoboro umwe urashobora kugera kuri 112G PAM4.Igipimo cyo kohereza cyose muri paki yose igera kuri 800G.Gusubira inyuma bihujwe na OSFP56, ugereranije nigihe kimwe cyo gukuba kabiri umuvuduko, wujuje ubuziranenge bwa IEEE 802.3CK;Nkigisubizo, igihombo cyo gutakaza kiziyongera cyane kandi intera yo kohereza umuringa wa pasiporo CABLE IO module izagabanuka.Hashingiwe ku mbogamizi zifatika zifatika, itsinda rya IEEE 802.3CK, ryashyizeho ibisobanuro 112G, ryagabanije uburebure ntarengwa bw’umuringa w’umuringa kugera kuri metero 2 hashingiwe ku mugozi wa 56G w’umuringa IO ufite umuvuduko ntarengwa wa metero 3.
QSFP-DD X 2 icyambu 1.6Tbps ikibaho
QQSFP -DD 800G izamuka irwanya umuyaga
Ubushobozi bwa data center bugenwa na seriveri, guhinduranya, hamwe nuburyo bwo guhuza buringaniza kandi bigasunikana kugana ku iterambere ryihuse, ridahenze.Guhindura tekinoroji niyo mbaraga nyamukuru itwara imyaka myinshi.Nkuko OFC2021 igiye kurangira vuba aha, abakora ibikorwa byitumanaho rya optique nka Intel, Finisar, Xechuang, Opticexpress na New Yisheng bose berekanye moderi ya optique ya 800G.Muri icyo gihe, amasosiyete yo mu mahanga ya optique ya chip yerekanaga ibicuruzwa byo mu rwego rwo hejuru kuri 800G, kandi gahunda gakondo irashobora kuba igifite umwanya mugihe cya 800G.Twibwira ko inzira ya tekinoroji ya 800G optique irushijeho gusobanuka, 800GDR8 na 2 * FR4 bifite ubushobozi bwingenzi;Nka OFC2021 nyamukuru module ya optique hamwe na optique ya chip optique yatangije ibicuruzwa bishya nyuma yikindi, igihe cyagenwe ninzira yikoranabuhanga rusange yo kuzamura 800G byasobanuwe.Igipimo cya data center optique module yinganda ikomeje gusubiramo, kandi ikiranga igihe kirekire cyo gukura cyagenwe.Twizera ko mugihe cya digitale nubwenge, guhora guturika kwimodoka ya data center byazanye icyifuzo cyo gukomeza guhinduranya moderi optique.Inzira ya tekinoroji isobanutse ya 800G yerekana ko 400G izaba nini-nini.
Iyo igipimo cyibimenyetso cya 25Gbps kizamuwe kugeza kuri 56Gbps yerekana ibimenyetso, kubera ko hashyizweho sisitemu yerekana ibimenyetso bya PAM4 (Pulse Amplitude Modulation) (itsinda rya IEEE 802.3BS), Ingingo yibanze yumurongo wibimenyetso byanyuze kumurongo wa Serdes Ethernet irazamuka gusa. kuva 12.89ghz kugeza 13.28ghz, kandi ikimenyetso cyibanze cyumwanya ntigihinduka cyane.Sisitemu ishobora gushyigikira itumanaho ryiza rya 25Gbps irashobora kuzamurwa kugera kuri 56Gbps yerekana ibimenyetso hamwe no gutezimbere gato.Kuzamura igipimo cya 56Gbps kugeza kuri 112Gbps igipimo cyibimenyetso ntabwo byoroshye.Sisitemu ya signal ya PAM4 yatangijwe mugihe igipimo cya 56Gbps cyatejwe imbere birashoboka cyane ko kizongera gukoreshwa ku gipimo cya 112Gbps.Ibi bihindura umurongo wibanze wa 112Gbps Ethernet signal kuri 26.56ghz, ikubye kabiri igipimo cya 56Gbps.Mu gisekuru cya 112Gbps, ibisabwa bya tekinoroji ya kabili bizahura nikizamini gisaba cyane.Kugeza ubu, 400Gbps ya kabili yihuta ihujwe nibicuruzwa.Ibirango byambere bikuze cyane cyane mubirango byamahanga, nka TE, LEONI, MOLEX, Amphenol, nibindi. Ibirango byimbere mu gihugu nabyo byatangiye kurenga mumyaka yashize.Duhereye kubikorwa byo gukora, ibikoresho nibikoresho, twakoze udushya twinshi.Kugeza ubu, hari imishinga yo murugo ikora umugozi wumuringa 800G, ariko ntabwo twakusanyije byinshi.Shenzhen Hongteda, Dongguan Zhongyou Electronics, Dongguan Jinxinuo, Itumanaho rya Shenzhen Simic, nibindi, ariko ingorane za tekiniki zihari ziri mubice byinsinga zambaye ubusa.Kugeza ubu, biragoye gukemura ibibazo byinshi byumuriro wamashanyarazi hamwe nibisabwa byoroheje byinsinga mugihe kimwe.Umugozi wumuringa wa DAC uzahura nigihe cyiterambere ryihuse.Hano hari bake mubakora insinga zaho.
Isoko rirahinduka vuba, kandi rizahinduka vuba vuba mugihe kizaza.Amakuru meza nuko intambwe igaragara kandi itanga icyizere imaze guterwa, kuva murwego rusanzwe kugeza muruganda, kugirango ibigo byamakuru bimuke kuri 400GB na 800GB.Ariko gukuraho inzitizi zikoranabuhanga ni kimwe cya kabiri cyikibazo.Igice cya kabiri ni igihe.Iyo urubanza rudakwiye kubaho, ikiguzi kizaba kinini.Inzira nyamukuru yikigo kiriho ni 100G.Mu bigo byoherejweho amakuru 100G, 25% ni umuringa, 50% ni fibre yuburyo bwinshi, naho 25% ni fibre imwe.Iyi mibare y'agateganyo ntabwo isobanutse neza, ariko kwiyongera gukenera kwaguka, ubushobozi, nubukererwe buke bitera kwimuka kumuvuduko wihuse.Buri mwaka rero, guhuza n'imihindagurikire y’ibicuruzwa binini binini ni ikizamini.Kugeza ubu, 100GB yuzuye isoko, biteganijwe ko umwaka utaha 400GB.Nubwo bimeze gurtyo, amakuru agenda aracyakomeza kwiyongera, igitutu cyibigo bizakomeza kwiyongera, nyuma ya 400G, QSFP-DD 800G yaje.
