Bisanzwe DAC yihuta ya kabili itondekanya

DAC umugozi wihuse(Direct Attach Cable) isanzwe isobanurwa nkumugozi utaziguye, uhuza umurongo wumuringa cyangwa umugozi wihuta.Byasobanuwe nkigiciro gito-kigufi-ihuza gahunda isimbuza optique.Impera zombi za kabili yihuta zifite modules Cable inteko, insimburangingo zidasimburwa, imitwe ya module hamwe ninsinga z'umuringa ntibishobora gutandukana, ariko ugereranije na optique module ikora optique ya kabili (Active Optical Cables), modules ihuza kumashanyarazi yihuta ikora ntabwo ufite lazeri ihenze ya optique nibindi bikoresho bya elegitoronike, kubwibyo kuzigama gukomeye mugiciro no gukoresha ingufu mubisabwa bigufi.Hamwe n'umuvuduko mwinshi wa Ethernet, kubara ibicu, interineti yibintu, hamwe na santere yamakuru, ibisabwa byinshi byashyizwe kubakoresha amakuru yikigo.Umuvuduko wamakuru mubyukuri uri munzira igana 400G, kubwibyo usibye guhuza muri 3-5m muri seriveri, DAC irashobora kandi gukoreshwa (metero 5-7 zikeneye gukoresha ibikoresho byihariye byo kubika kugirango byuzuze ibisabwa biranga).Ihuza rirenze izo ntera risanzwe ryakozwe na AOC.

10G SFP + kuri SFP + Umuvuduko mwinshi Umugozi

10G SFP + kugeza kuri SFP + DAC ikoresha insinga ya kabili ya twinaxial passiyo kandi ihuza na module ya SFP +, igaragaramo ubucucike bwinshi, imbaraga nke, igiciro gito, nubukererwe buke.

Ni ubuhe bwoko bwa 10G SFP + kugeza kuri SFP + insinga yihuta irahari?

Muri rusange, hari ubwoko butatu bwa 10G SFP + kugeza kuri SFP + insinga yihuta:

10G SFP + pasiporo y'umuringa wa pasiporo yihuta cyane (DAC),

10G SFP + Umuringa ukora cyane Umuyoboro wihuse (ACC),

10G SFP + Umugozi ukora neza (AOC),

Birakwiriye guhuza imiyoboro muri rack no hagati yumurongo wegeranye kandi birahenze cyane.

SFP + pasiporo yumuringa yibanze yihuta itanga umugozi wamashanyarazi utaziguye hagati yimpande zombi zumugozi uhuye, kandi intera ihuza irashobora kugera kuri 12m.Ariko, kubera uburemere buremereye bwumugozi no gusuzuma ikibazo cyuburinganire bwibimenyetso, uburebure bwabwo bukoreshwa Muri rusange bigarukira kuri 7m na 10m.

40G QSFP + kuri QSFP + Umuyoboro wihuse

Umugozi wihuta wa 40G (DAC) bivuga umugozi uhuza hamwe na fibre optique ya fibre optique ku mpande zombi, zishobora kugera kuri 40Gbps yohereza amakuru kandi nigisubizo cyihuse cyihuse cyo guhuza.Imiyoboro isanzwe ya 40G yihuta irashobora kugabanywamo ubwoko butatu: 40G QSFP + kugeza QSFP + DAC, 40GQSFP + kugeza 4 * SFP + DAC, na 40GQSFP + kugeza 4XFP + DAC.

40G QSFP + kugeza kuri QSFP + DAC igizwe na 40G QSFP + transceiver optique hamwe ninsinga z'umuringa.Uyu mugozi wihuta urashobora gukoreshwa kugirango umenye guhuza ibyambu 40G QSFP + bihari kuri 40G QSFP + ibyambu, mubisanzwe muri 7m gusa.intera.

40G QSFP + kugeza 4 × SFP + DAC igizwe na 40G QSFP + optique ya optique, insinga y'umuringa hamwe na bine 10G SFP + optique.Impera imwe ni 40G QSFP + Imigaragarire, yujuje ibisabwa na SFF-8436, naho iyindi ni enye 10G SFP +.. muri rusange muri 7m gusa.Intera, kuri ubu nubukungu bworoshye kandi bworoshye kugirango uhindure icyambu.

40G QSFP + kugeza 4XFP DAC igizwe na 40G QSFP + optique ya optique, insinga z'umuringa hamwe na bine 10G XFP.Kubera ko XFP fibre optique transceiver idafite umugozi wumuringa wa DAC wumuringa, indishyi yikimenyetso yatanzwe nigikoresho ni gito, kandi gutakaza insinga ubwayo nini cyane.Irashobora gukoreshwa gusa mugukwirakwiza intera ngufi, mubisanzwe mumwanya wa 2m.Kubwibyo, iyi kabili yihuta irashobora gukoreshwa kuri Interconnects iriho ibyambu 40G QSFP + kugeza kuri 4 XFP.

25G SFP28 kugeza kuri SFP28 Umuyoboro wihuse

25.

100G QSFP28 kugeza QSFP28 Umuyoboro wihuse

100G QSFP28 kugeza QSFP28 DAC irashobora guha abakiriya ubushobozi bwoguhuza amakuru 100G yumurongo mugari woguhuza amakuru, gutanga imiyoboro 4 duplex, buri muyoboro urashobora gushyigikira igipimo cya 25Gb / s, kandi umurongo mugari ni 100Gb / s, bijyanye na SFF-8436 ibisobanuro, bikoreshwa muguhuza ibikoresho bifite ibyambu bya QSFP28.

100G QSFP28 kugeza 4 * SFP28 Umugozi wihuse

Impera imwe ya 100G QSFP28 kugeza 4 SFP28 DAC ni interineti 100G QSFP28, naho iyindi ni 4 25G SFP28, ishobora guha abakiriya ubushobozi bwo guhuza amakuru 100G nini cyane, hamwe na SFF-8665 / SFF-8679, IEEE 802.3bj hamwe na InfinibandEDR ibipimo, Byakoreshejwe cyane muri data center cyangwa super computing center sisitemu.
