Ikhebula le-DAC elisheshayo(Ikhebula Elinamathisela Ngokuqondile) ngokuvamile lihunyushwa ngokuthi ikhebula eliqondile, ikhebula lethusi elixhuma ngqo noma ikhebula lesivinini esikhulu. Lichazwa njengohlelo lokuxhumanisa ibanga elifushane olubiza kancane oluthatha indawo yamamojula e-optical. Zombili iziphetho zekhebula lesivinini esikhulu zinamamojula Ama-Cable assembly, ama-port angashintshwa, amakhanda emojula kanye nezintambo zethusi azikwazi ukuhlukaniswa, kodwa uma kuqhathaniswa nezintambo ze-optical ezisebenzayo zemojula ye-optical (Izintambo Ezisebenzayo Zokukhanya), amamojula okuxhumanisa ezintanjeni zesivinini esikhulu awanawo ama-laser e-optical abizayo nezinye izingxenye ze-elekthronikhi, ngakho-ke ukonga okukhulu ekusetshenzisweni kwezindleko kanye namandla ezinhlelweni zokusebenza zebanga elifushane. Ngejubane eliphezulu le-Ethernet, i-cloud computing, i-Internet of Things, kanye nezikhungo zedatha ezibonakalayo, kubekwe izidingo ezengeziwe kubasebenzisi bezikhungo zedatha. Ijubane ledatha empeleni lisendleleni eya ku-400G, ngakho-ke ngaphezu kokuxhumeka okungaphakathi kwama-3-5m kuseva, i-DAC ingasetshenziswa futhi (amamitha angu-5-7 adinga ukusebenzisa izinto ezikhethekile zokuvikela ukuze kuhlangatshezwane nezidingo zesici). Ukuxhumeka ngale kwala mabanga ngokuvamile kuqashelwa yi-AOC.
Isivinini Esiphezulu kusuka ku-10G SFP+ kuya ku-SFP+ Ikhebula
I-10G SFP+ kuya ku-SFP+ DAC isebenzisa ikhebula le-twinaxial elingasebenzi futhi ixhuma ngqo kwimojula ye-SFP+, equkethe ukuminyana okuphezulu, amandla aphansi, izindleko eziphansi, kanye nokubambezeleka okuphansi.
Yiziphi izinhlobo zezintambo zesivinini esikhulu ezisuka ku-10G SFP+ kuya ku-SFP+ ezitholakalayo?
Ngokuvamile, kunezinhlobo ezintathu zezintambo zesivinini esikhulu ezisuka ku-10G SFP+ kuya ku-SFP+:
Ikhebula le-10G SFP+ eliyi-passive copper core high-speed (DAC),
Ikhebula le-Copper Core eli-10G SFP+ elisebenzayo (i-ACC),
Ikhebula le-Optical elisebenzayo le-10G SFP+ (AOC),
Zifanelekela ukuxhumana kwenethiwekhi ngaphakathi kwe-rack naphakathi kwama-rack aseduze futhi zingabizi kakhulu.
Ikhebula le-SFP+ eliyi-cable core elisheshayo eliyi-passive copper core linikeza ukuxhumana okuqondile kagesi phakathi kwezinhlangothi ezimbili zekhebula elihambisanayo, futhi ibanga lokuxhumana lingafinyelela ku-12m. Kodwa-ke, ngenxa yesisindo esinzima sekhebula kanye nenkinga yobuqotho besiginali, ubude bokusetshenziswa kwalo ngokuvamile bunqunyelwe phakathi kwamamitha angu-7 no-10.
Ikhebula le-40G QSFP+ kuya ku-QSFP+ Elisheshayo
Ikhebula lesivinini esiphezulu le-40G (i-DAC) libhekisela kukhebula elixhumanisayo elinama-transceivers e-fiber optic kuzo zombili izinhlangothi, elingafinyelela ukudluliswa kwedatha kwe-40Gbps futhi liyisisombululo sokuxhumanisa ngesivinini esiphezulu esingabizi kakhulu. Izintambo zesivinini esiphezulu ze-40G ezivame kakhulu zingahlukaniswa zibe izinhlobo ezintathu: 40G QSFP+ kuya ku-QSFP+DAC, 40GQSFP+ kuya ku-4*SFP+DAC, kanye ne-40GQSFP+ kuya ku-4XFP+DAC.
I-40G QSFP+ kuya ku-QSFP+ DAC yakhiwe ngama-transceiver amabili e-40G QSFP+ optical kanye nezintambo zethusi. Le ntambo yesivinini esikhulu ingasetshenziswa ukuxhumanisa amachweba e-40G QSFP+ akhona namachweba e-40G QSFP+, ngokuvamile ngaphakathi kwebanga elingu-7m.
I-40G QSFP+ kuya ku-4×SFP+ DAC yakhiwe nge-transceiver eyodwa ye-40G QSFP+ optical, i-copper core wire kanye nama-transceiver amane e-10G SFP+. Uhlangothi olulodwa yi-interface ye-40G QSFP+, ehlangabezana nezidingo ze-SFF-8436, kanti olunye uhlangothi yi-interface ezine ze-10G SFP+. , ngokuhambisana nezidingo ze-SFF-8432, esetshenziswa kakhulu ukufeza ukuxhumana phakathi kwemishini ye-40G ne-10G (i-NIC/HBA/CNA, imishini yokushintsha kanye neseva), ngokwezidingo zamakhasimende zobude bezintambo kuzo zombili izinhlangothi, ngokuvamile ngaphakathi kwamamitha angu-7 kuphela. Ibanga, okwamanje liyindlela engabizi kakhulu futhi elula yokufinyelela ukuguqulwa kwe-switch port.
I-40G QSFP+ kuya ku-4XFP DAC yakhiwe yi-transceiver eyodwa ye-40G QSFP+ optical, i-copper core wire kanye nama-transceiver amane e-10G XFP optical. Njengoba i-transceiver ye-fiber optic ye-XFP ingenayo indinganiso yekhebula lethusi le-DAC, isinxephezelo sesignali esinikezwa yidivayisi siphansi, futhi ukulahlekelwa yikhebula ngokwalo kukhulu kakhulu. Ingasetshenziswa kuphela ekudluliseni ibanga elifushane, ngokuvamile ngaphakathi kwebanga elingamamitha amabili. Ngakho-ke, le khebula yesivinini esikhulu ingasetshenziswa kuma-Interconnect akhona ama-port angu-40G QSFP+ kuma-port angu-4 e-XFP.
Ikhebula le-25G SFP28 kuya ku-SFP28 Elisheshayo
I-25G SFP28 kuya ku-SFP28 DAC inganikeza amakhasimende ikhono lokuxhumana kwedatha le-25G eliphezulu, ngokuhambisana ne-IEEE P802.3by Ethernet standard kanye ne-SFF-8402 SFP28, futhi isetshenziswa kabanzi ezimweni zesistimu yesikhungo sedatha noma yesikhungo se-supercomputing.
Ikhebula lesivinini esiphezulu eliyi-100G QSFP28 kuya ku-QSFP28
I-100G QSFP28 kuya ku-QSFP28 DAC inganikeza amakhasimende amandla okuxhumana kwedatha ye-100G ephezulu ye-bandwidth, ihlinzeka ngeziteshi ezine ze-duplex, isiteshi ngasinye singasekela izinga lokusebenza elifika ku-25Gb/s, kanti i-bandwidth yokuhlanganisa ingu-100Gb/s, ngokuhambisana nencazelo ye-SFF-8436, esetshenziswa ekuxhumekeni phakathi kwamadivayisi anezimbobo ze-QSFP28.
Ikhebula lesivinini esiphezulu le-100G QSFP28 kuya ku-4*SFP28
Ukuphela okukodwa kwe-100G QSFP28 kuya ku-4 SFP28 DAC kuyi-interface ye-100G QSFP28, kanti okunye ukuphela kuyi-interface ye-4 25G SFP28, enganikeza amakhasimende amandla okuxhumana kwedatha ye-100G ephezulu, ngokuhambisana nezindinganiso ze-SFF-8665/SFF-8679, IEEE 802.3bj kanye ne-InfinibandEDR, ezisetshenziswa kabanzi ezikhungweni zedatha noma ezikhungweni ze-super computing.
