Icyiciro rusange cya DAC cy'insinga zihuta cyane

Insinga yihuta ya DAC(Umugozi wo Guhuza Direct) muri rusange usobanurwa nk'umugozi utaziguye, umugozi uhuza direct-connect cyangwa umugozi wihuta cyane. Usobanurwa nk'uburyo bwo guhuza intera ngufi buhendutse busimbura module za optique. Impera zombi z'umugozi wihuta cyane zifite modules Assemblies za cable, ports zidasimburwa, module heads n'umugozi w'umuringa ntibishobora gutandukanywa, ariko ugereranije n'imigozi ya optique module (Active Optical Cables), modules zo guhuza ku migozi yihuta cyane ntabwo zifite lasers zihenze z'amashanyarazi n'ibindi bice by'ikoranabuhanga, bityo kuzigama amafaranga menshi mu gukoresha ingufu mu bikorwa bya hafi. Hamwe n'umuvuduko mwinshi wa Ethernet, cloud computing, Internet of Things, na virtual data centers, hari byinshi bisabwa byashyizwe ku bakoresha centre za data. Umuvuduko w'amakuru uri mu nzira igera kuri 400G, bityo uretse guhuza muri metero 3-5 muri seriveri, DAC nayo irashobora gukoreshwa (metero 5-7 zigomba gukoresha ibikoresho byihariye byo gukingira kugira ngo zuzuze ibisabwa byihariye). Umugozi urenze izi ntera muri rusange ugerwaho na AOC.

Umuvuduko wo hejuru uva kuri 10G SFP+ ujya kuri SFP+ Insinga

10G SFP+ kuri SFP+ DAC ikoresha insinga ya twinaxial idakora kandi ihuzwa neza na module ya SFP+, ifite ubucucike bwinshi, ingufu nke, ikiguzi gito, kandi idatererwa nke.

Ni ubuhe bwoko bwa 10G SFP+ kuri SFP+ insinga zihuta cyane ziboneka?

Muri rusange, hari ubwoko butatu bw'insinga zihuta cyane za 10G SFP+ kuva kuri SFP+:

Insinga yihuta cyane ya 10G SFP+ y'umuringa udafite umuvuduko (DAC),

Umugozi w'umuringa ukoresha 10G SFP+ Active Copper Core High Speed ​​​​(ACC),

Insinga ya 10G SFP+ Active Optical (AOC),

Bikwiriye guhuza umuyoboro w'itumanaho mu kirahuri no hagati y'amakirahuri yegeranye kandi birahendutse cyane.

Insinga yihuta cyane ya SFP+ ikoreshwa mu mugozi w’umuringa udafite umuvuduko itanga ikoranabuhanga rihuza impande zombi z’insinga, kandi intera yo kuyihuza ishobora kugera kuri metero 12. Ariko, bitewe n’uburemere bukabije bw’insinga no ku kibazo cy’ubuziranenge bw’ibimenyetso, uburebure bwayo muri rusange bugarukira hagati ya metero 7 na metero 10.

Umugozi w'umuvuduko wihuta wa 40G QSFP+ ujya kuri QSFP+

Insinga yihuta ya 40G (DAC) yerekeza ku nsinga ihuza ifite transceivers za fiber optique ku mpande zombi, ishobora kohereza amakuru ya 40Gbps kandi ni igisubizo gihendutse cyo guhuza amakuru yihuta cyane. Insinga zigezweho za 40G zishobora kugabanywamo ubwoko butatu: 40G QSFP+ kuri QSFP+DAC, 40GQSFP+ kuri 4*SFP+DAC, na 40GQSFP+ kuri 4XFP+DAC.

40G QSFP+ kugeza kuri QSFP+ DAC igizwe na transceivers ebyiri za 40G QSFP+ optique hamwe n'insinga z'umuringa. Iyi nsinga yihuta cyane ishobora gukoreshwa mu guhuza imiyoboro ya 40G QSFP+ isanzweho n'imiyoboro ya 40G QSFP+, muri rusange ikaba iri mu ntera ya metero 7 gusa.

40G QSFP+ kugeza kuri 4×SFP+ DAC igizwe na transceiver imwe ya 40G QSFP+ optique, insinga y'umuringa n'udukoresho tune twa 10G SFP+ optique. Impande imwe ni 40G QSFP+ interface, yujuje ibisabwa na SFF-8436, naho iy'indi mpera ni 10G SFP+ interfaces enye. , hakurikijwe ibisabwa na SFF-8432, ikoreshwa cyane cyane mu guhuza ibikoresho bya 40G na 10G (NIC/HBA/CNA, ibikoresho bya switch na seriveri), hakurikijwe ibyo umukiriya akeneye ku burebure bw'insinga zombi, muri rusange muri metero 7 gusa. Intera, ubu ni yo ihendutse kandi yoroshye kuyikoresha mu guhindura umuyoboro wa switch.

40G QSFP+ kugeza kuri 4XFP DAC igizwe na transceiver imwe ya 40G QSFP+ optique, insinga y'umuringa n'ibyuma bine bya 10G XFP optique. Kubera ko transceiver ya fiber optique ya XFP idafite insinga y'umuringa ya DAC, uburyo bwo kwishyura ikimenyetso butangwa n'igikoresho ni buke, kandi igihombo cy'insinga ubwayo ni kinini cyane. Ishobora gukoreshwa gusa mu kohereza intera ngufi, muri rusange iri mu ntera ya metero 2. Kubwibyo, iyi nsinga yihuta cyane ishobora gukoreshwa mu guhuza imiyoboro ya 40G QSFP+ isanzweho n'imiyoboro 4 ya XFP.

Insinga yihuta cyane ya 25G SFP28 ijya kuri SFP28

25G SFP28 kuri SFP28 DAC ishobora guha abakiriya ubushobozi bwo guhuza amakuru bwa 25G bufite bandwidth nyinshi, hakurikijwe IEEE P802.3 by Ethernet standard na SFF-8402 SFP28, kandi ikoreshwa cyane mu buryo bwa mudasobwa cyangwa supercomputer center system.

Umugozi w'umuvuduko wo hejuru wa 100G QSFP28 kugeza kuri QSFP28

100G QSFP28 kugeza kuri QSFP28 DAC ishobora guha abakiriya ubushobozi bwo guhuza amakuru ya 100G ifite umuyoboro munini w’amakuru, itanga imiyoboro ine y’amakuru abiri, buri muyoboro ushobora gushyigikira imikorere ya 25Gb/s, kandi umuyoboro w’amakuru uteranyirizwa hamwe ni 100Gb/s, hakurikijwe amabwiriza ya SFF-8436, akoreshwa mu guhuza ibikoresho bifite imiyoboro ya QSFP28.

Insinga yihuta cyane ya 100G QSFP28 kugeza kuri 4 * SFP28

Impande imwe ya 100G QSFP28 kugeza kuri 4 SFP28 DAC ni 100G QSFP28 interface, naho indi mpera ni 4 25G SFP28 interfaces, zishobora guha abakiriya ubushobozi bwo guhuza amakuru ya 100G, hakurikijwe amahame ya SFF-8665/SFF-8679, IEEE 802.3bj na InfinibandEDR, Ikoreshwa cyane mu buryo bwa mudasobwa cyangwa super computing center system.
