Ukuhlukaniswa kwekhebula elisheshayo le-DAC elivamile

Intambo ye-DAC enesivinini esikhulu(I-Direct Namathisela Ikhebula) ngokuvamile ihunyushwa njengekhebula eliqondile, intambo yethusi yokuxhuma ngokuqondile noma ikhebula elinesivinini esikhulu.Ichazwa njengesikimu soxhumano lwebanga elifushane esibiza kancane esithatha indawo yamamojula abonakalayo.Zombili iziphetho zekhebula elinesivinini esiphezulu zinamamojula Amakhebula ahlanganisayo, izimbobo ezingashintshiwe, amakhanda emojula nezintambo zethusi azikwazi ukuhlukaniswa, kodwa uma kuqhathaniswa nezintambo ezibonakalayo ezisebenzayo (Active Optical Cables), amamojula okuxhuma kwizintambo ezinesivinini esikhulu ayinawo ama-laser okukhanya abizayo nezinye izingxenye ze-elekthronikhi, ngakho-ke ukonga okuphawulekayo ezindlekweni nasekusetshenzisweni kwamandla ezinhlelweni zebanga elifushane.Ngezivinini eziphakeme ze-Ethernet, i-cloud computing, I-inthanethi Yezinto, nezikhungo zedatha ebonakalayo, izidingo ezengeziwe zibekwe kuma-opharetha esikhungo sedatha.Isivinini sedatha empeleni sisendleleni eya ku-400G, ngakho-ke ngaphezu kokuxhumeka ngaphakathi kwe-3-5m kuseva, i-DAC ingasetshenziswa (amamitha angu-5-7 adinga ukusebenzisa izinto zokuvikela ezikhethekile ukuhlangabezana nezidingo zesici).Uxhumano ngale kwala mabanga ngokuvamile lutholwa yi-AOC.

I-10G SFP+ kuya ku-SFP+ High Speed Ikhebula

I-10G SFP+ kuya ku-SFP+ DAC isebenzisa umhlangano wekhebula we-twinaxial ongenzi lutho futhi ixhuma ngqo kumojula ye-SFP+, equkethe ukuminyana okuphezulu, amandla aphansi, izindleko eziphansi, nokubambezeleka okuphansi.

Yiziphi izinhlobo zezintambo ze-10G SFP+ kuya ku-SFP+ ezitholakalayo?

Ngokuvamile, kunezinhlobo ezintathu zezintambo ze-10G SFP+ kuya ku-SFP+ ezinesivinini esikhulu:

10G SFP+ passive copper core high-speed cable (DAC),

I-10G SFP+ Active Copper Core High Speed ​​​​Cable (ACC),

I-10G SFP+ Active Optical Cable (AOC),

Afanele ukuxhumana kwenethiwekhi ngaphakathi kwendawo yokubeka naphakathi kwama-rack aseduze futhi abiza kakhulu.

Ikhebula le-SFP + ye-copper core high-speed inikezela nge-interface eqondile kagesi phakathi kwamaphethelo amabili ekhebula elihambisanayo, futhi ibanga lokuxhuma lingafinyelela ku-12m.Kodwa-ke, ngenxa yesisindo esinzima sekhebula futhi ucabangela inkinga yobuqotho besignali, ubude bayo bokusetshenziswa Ngokuvamile bukhawulelwe phakathi kuka-7m no-10m.

I-40G QSFP+ kuya ku-QSFP+ Ikhebula Lejubane Eliphezulu

Ikhebula le-40G high-speed (DAC) libhekisela kukhebula lokuxhuma elinama-transceivers e-fiber optic emikhawulweni yomibili, engafinyelela ukudluliswa kwedatha ye-40Gbps futhi iyisixazululo esingabizi kakhulu sokuxhumanisa isivinini esikhulu.Izintambo ezivame kakhulu ze-40G zesivinini 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 yenziwe ngama-transceiver optical amabili we-40G QSFP+ kanye nezintambo eziwumgogodla wethusi.Le khebula enesivinini esiphezulu ingasetshenziswa ukuze kuqashwe ukuxhumana kwezimbobo ezikhona ze-40G QSFP+ kumachweba angu-40G QSFP+, ngokuvamile phakathi kwama-7m kuphela.ibanga.

I-40G QSFP + kuya ku-4 × SFP + DAC yenziwe nge-40G QSFP + i-transceiver optical eyodwa, i-copper core wire kanye nama-transceivers amane we-10G SFP + optical.Ukuphela okukodwa kuyi-interface ye-40G QSFP +, ehlangabezana nezidingo ze-SFF-8436, kanti enye i-interface ine-10G SFP+ ezine., ngokuhambisana nezidingo ze-SFF-8432, esetshenziselwa kakhulu ukubona ukuxhumana phakathi kwemishini ye-40G ne-10G (NIC/HBA/CNA, shintsha imishini kanye neseva), ngokuya ngezidingo zekhasimende zobude bezintambo kuzo zombili iziphetho, ngokuvamile kuphela phakathi 7m.Ibanga, okwamanje iyonga kakhulu futhi kulula ukufeza ukuguqulwa kwembobo yokushintsha.

I-40G QSFP+ kuya ku-4XFP DAC yenziwe nge-transceiver eyodwa ye-40G QSFP+, i-copper core wire kanye nama-transceiver amane we-10G XFP.Njengoba i-XFP fiber optic transceiver ingenalo izinga lekhebula le-DAC yethusi, isinxephezelo sesignali esinikezwe idivayisi siphansi, futhi ukulahlekelwa kwekhebula ngokwalo kukhulu kakhulu.Ingasetshenziselwa kuphela ukudluliswa kwebanga elifushane, ngokuvamile phakathi kwebanga elingu-2m.Ngakho-ke, le ntambo enesivinini esiphezulu ingasetshenziselwa I-Interconnects ekhona 40G QSFP+ amachweba kumachweba 4 XFP.

25G SFP28 kuya ku-SFP28 High Speed ​​Cable

I-25G SFP28 kuya ku-SFP28 DAC ingahlinzeka amakhasimende nge-25G ephezulu yomkhawulokudonsa wokuxhumana wedatha, ngokuhambisana ne-IEEE P802.3by Ethernet standard kanye ne-SFF-8402 SFP28, futhi isetshenziswa kabanzi kusikhungo sedatha noma izimo zesistimu ye-supercomputing

I-100G QSFP28 kuya ku-QSFP28 High Speed ​​Cable

I-100G QSFP28 kuya ku-QSFP28 DAC inganikeza amakhasimende amandla okuxhumana kwedatha ye-100G ephezulu yomkhawulokudonsa, ehlinzeka ngeziteshi ze-4 duplex, isiteshi ngasinye singasekela kuze kufike ku-25Gb / s izinga lokusebenza, futhi umkhawulokudonsa wokuhlanganisa yi-100Gb / s, ngokuhambisana ne-SFF-8436 Ukucaciswa, okusetshenziswe ku-Connection phakathi kwamadivayisi anezimbobo ze-QSFP28.

I-100G QSFP28 kuya ku-4 * SFP28 Ikhebula Lejubane Eliphezulu

Ukuphela okukodwa kwe-100G QSFP28 kuya ku-4 SFP28 DAC iyisixhumi esibonakalayo se-100G QSFP28, kanti esinye isiphetho yi-4 25G SFP28 interfaces, enganikeza amakhasimende amandla okuxhumana kwedatha ye-100G ephezulu yomkhawulokudonsa, ngokuhambisana ne-SFF-8665 / SFF-8679, IEEE 802.3bj kanye namazinga e-InfinibandEDR, Asetshenziswa kakhulu kusikhungo sedatha noma ezimeni zesistimu ye-super computing center.
