Kuri ubu, module za IO za SFP28/SFP56 na QSFP28/QSFP56 zikoreshwa cyane cyane mu guhuza switches na switches na seriveri mu makabati asanzwe ku isoko. Mu gihe cy'igipimo cya 56Gbps, kugira ngo abantu bakurikirane ubucucike bw'imiyoboro, barushijeho guteza imbere module ya QSFP-DD IO kugira ngo bagere ku bushobozi bwa port ya 400G. Kubera ko igipimo cy'ikimenyetso cyikubye kabiri, ubushobozi bwa port ya module ya QSFP DD bwikubye kabiri bugera kuri 800G, yitwa OSFP112. Ifite imiyoboro umunani yihuta cyane, kandi igipimo cyo kohereza umuyoboro umwe gishobora kugera kuri 112G PAM4. Igipimo cyose cyo kohereza umuyoboro wa paki yose kigera kuri 800G. Gusubira inyuma bihuye na OSFP56, ugereranije n'igihe kimwe cyo kongera umuvuduko kabiri, byujuje ibipimo ngenderwaho bya IEEE 802.3CK; Kubera iyo mpamvu, igihombo cy'imiyoboro kiziyongera cyane kandi intera yo kohereza umuyoboro wa CABLE IO module izarushaho kugabanuka. Hashingiwe ku nzitizi zifatika, itsinda rya IEEE 802.3CK, ryashyizeho ibisobanuro bya 112G, ryagabanyije uburebure ntarengwa bw'insinga z'umuringa kugeza kuri metero 2 hashingiwe ku nsinga z'umuringa za 56G IO zifite umuvuduko ntarengwa wa metero 3.
Ikibaho cyo gupima cya QSFP-DD X 2 cya 1.6Tbps
QQSFP -DD 800G iraza ihanganye n'umuyaga
Ubushobozi bw'ikigo cy'amakuru bugenwa na seriveri, swichi, n'ibintu bihuza bihuza kandi bigasunika hamwe mu iterambere ryihuse kandi rihendutse. Ikoranabuhanga ryo guhinduranya ryabaye imbaraga nyamukuru mu myaka myinshi ishize. Mu gihe cya vuba aha, inganda zikora itumanaho rya optique nka Intel, Finisar, Xechuang, Opticexpress na New Yisheng zose zagaragaje module za optique za 800G. Muri icyo gihe, amasosiyete acuruza optique mu mahanga yagaragaje ibikoresho bya optique bya 800G, kandi gahunda gakondo ishobora kuba igifite umwanya mu gihe cya 800G. Dutekereza ko inzira y'ikoranabuhanga rya optique module ya 800G irushaho kuba nziza, 800GDR8 na 2 * FR4 bifite ubushobozi bunini; Kubera ko amasosiyete acuruza optique ya OFC2021 na optique chips yatangije ibicuruzwa bishya kimwe ku kindi, uburyo bwo kuvugurura 800G bwarasobanuwe. Igipimo cy'inganda zikora optique centre gikomeje kwiyongera, kandi imiterere y'iterambere ry'igihe kirekire yaragenwe. Twizera ko muri iki gihe cyo gukoresha ikoranabuhanga n'ubutasi, kwiyongera gukabije kw'abakoresha ikoranabuhanga mu bigo by'amakuru byatumye habaho icyifuzo cyo gukomeza gukoresha modules optique. Inzira y'ikoranabuhanga isobanutse neza ya 800G igaragaza ko 400G izaba nini.
Iyo igipimo cy'ikimenyetso cya 25Gbps cyazamuwe kikagera ku gipimo cy'ikimenyetso cya 56Gbps kiriho ubu, bitewe no gushyirwaho kwa sisitemu y'ikimenyetso ya PAM4 (Pulse Amplitude Modulation) (IEEE 802.3BS group), aho ikimenyetso cyoherezwa kuri Serdes Ethernet kigera gusa kuri 12.89ghz kikagera kuri 13.28ghz, kandi aho ikimenyetso cyoherezwa ntabwo gihinduka cyane. Sisitemu zishobora gushyigikira kohereza neza ibimenyetso bya 25Gbps zishobora kongerwaho kugeza ku gipimo cy'ikimenyetso cya 56Gbps hamwe no kunoza gato. Kuzamura kuva ku gipimo cy'ikimenyetso cya 56Gbps kikagera ku gipimo cy'ikimenyetso cya 112Gbps ntabwo byoroshye cyane. Sisitemu y'ikimenyetso ya PAM4 yatangijwe ubwo igipimo cya 56Gbps cyategurwaga, birashoboka cyane ko ishobora kongera gukoreshwa ku gipimo cya 112Gbps. Ibi bihindura aho ikimenyetso cya Ethernet cya 112Gbps kikagera kuri 26.56ghz, bikubye kabiri igipimo cy'ikimenyetso cya 56Gbps. Mu gukora igipimo cya 112Gbps, ibisabwa mu ikoranabuhanga rya cable bizahura n'igeragezwa rikomeye. Kugeza ubu, insinga yihuta ya 400Gbps ihujwe n'ibicuruzwa. Ibigo bikuze cyane cyane ni ibigo byo mu mahanga, nka TE, LEONI, MOLEX, Amphenol, nibindi. Ibigo byo mu gihugu nabyo byatangiye kurenga mu myaka ya vuba aha. Uhereye ku nganda, ibikoresho n'ibikoresho, twakoze udushya twinshi. Kugeza ubu, hari ibigo byo mu gihugu bikora insinga z'umuringa za 800G, ariko nta byinshi twakusanyije. Shenzhen Hongteda, Dongguan Zhongyou Electronics, Dongguan Jinxinuo, Shenzhen Simic Communication, nibindi, ariko ikibazo cya tekiniki kiri ahanini mu gice cy'insinga zidafite icyuho. Kugeza ubu, biragoye gukemura ibipimo by'imikorere y'amashanyarazi ku nshuro nyinshi hamwe n'ibisabwa byo koroha kw'insinga icyarimwe. Insinga z'umuringa za DAC zizahura n'igihe cy'iterambere ryihuse. Hari abakora insinga bake gusa bo mu gihugu.
Isoko ririmo guhinduka vuba, kandi rizatera imbere vuba mu gihe kizaza. Inkuru nziza ni uko hari intambwe ikomeye kandi ishimishije yatewe, kuva ku bigo bigenzura kugeza ku nganda, kugira ngo ibigo bitanga amakuru bishobore kugera kuri 400GB na 800GB. Ariko gukuraho inzitizi z'ikoranabuhanga ni kimwe cya kabiri cy'imbogamizi. Igice gisigaye ni igihe. Iyo habayeho gusesengura nabi, ikiguzi kizaba kinini. Igice cy'ingenzi cy'ikigo gitanga amakuru cyo mu gihugu ni 100G. Mu bigo bitanga amakuru bya 100G, 25% ni umuringa, 50% ni fibre nyinshi, na 25% ni fibre imwe. Iyi mibare y'agateganyo ntabwo ari yo nyayo, ariko gukenera bandwidth, ubushobozi, no kugabanuka kw'igihe biri gutuma abantu bimuka ku muvuduko wa interineti wihuta. Bityo rero buri mwaka, guhuza no kubaho kw'ibigo bitanga amakuru binini mu bicu ni ikizamini. Kuri ubu, 100GB irimo kuzura ku isoko, aho 400GB yitezwe umwaka utaha. Nubwo bimeze gutyo, urujya n'uruza rw'amakuru ruracyakomeza kwiyongera, igitutu ku bigo by'amakuru kizakomeza kwiyongera, nyuma ya 400G, QSFP-DD 800G yaraje.
