Umugozi wa AOCvs Umugozi wa DAC: Nibyiza kuri wewe

1. Niki insinga za DAC na AOC zihuriyehe?
Byombi DAC na AOC nibisanzwe bya cabling ibisubizo byurusobekerane rwamakuru kandi mubisanzwe bikoreshwa muburyo bwihuse, bwizewe cyane bwoguhuza no guhererekanya bisabwa nibigo byamakuru, mudasobwa zikora cyane, hamwe nububiko bunini bwo kubika.Impera zabo zombi zifite inteko ziteranijwe hamwe na transceiver yarangiye, ihujwe nibyambu byonyine.Uretse ibyo, insinga za DAC na AOC zishobora gukorwa mu burebure butandukanye kugira ngo zishyigikire ibipimo bitandukanye byo kohereza, nka 10G SFP DAC / AOC, umugozi wa 25G AOC, umugozi wa 40G DAC, na 100G AOC.

2. Ibyiza n'ibibi bya DAC Cable

Ibyiza byo Kwomekaho Umuringa

Ibiciro Byinshi - Muri rusange, igiciro cyinsinga z'umuringa kiri hasi cyane ugereranije na fibre optique.Igiciro cyinsinga z'umuringa pasiporo ni inshuro 2 kugeza kuri 5 zihendutse kuruta insinga za fibre z'uburebure bumwe.Kubwibyo, gukoresha insinga zihuta nabyo bizagabanya ibiciro bya cabling yikigo cyose.

Gukoresha ingufu nkeya - Umuvuduko mwinshi DAC (umugozi utaziguye) ukoresha ingufu nke (gukoresha ingufu ni zeru) kubera ko insinga za pasiporo zidasaba amashanyarazi.Gukoresha ingufu z'insinga z'umuringa zikora muri rusange ni 440mW.Niba ukoresheje umugozi wumuringa utaziguye aho gukoresha insinga za fibre ya AOC, urashobora kuzigama ibihumbi magana kilowat yumuriro wamashanyarazi.

Biraramba cyane - Byakozwe hamwe nuburyo bwo guhuza butagira ingano ya module ya optique na kabili ya optique, igabanya igiciro kandi ikemeza ko icyambu cya optique kitagaragajwe n ivumbi nibindi byangiza.Kubwibyo, DAC ntabwo ishobora kwangirika cyane.

 Ibyiza byo Kumugereka wumuringa

Imwe mu mbogamizi z'umugozi wa DAC ni uko iremereye kandi nini kuruta AOCs.Byongeye kandi, birashoboka cyane ku ngaruka zo kwivanga kwa electronique no kwiyegereza intera ndende kubera ibimenyetso byamashanyarazi byanyuze hagati yimpande zombi.

3. Ibyiza n'ibibi bya AOC Cable

Ibyiza bya AOC

Uburemere bworoheje-Umugozi ukora optique ugizwe na optique ya optique hamwe na fibre optique yamashanyarazi, uburemere bwayo ni kimwe cya kane cyumuringa utaziguye, kandi igice kinini ni kimwe cya kabiri cyumuringa.

Intera ndende-fibre ya AOC irashobora gutanga uburyo bunini kandi burebure bwo kugera kuri 100-300m bitewe nubushyuhe bwiza bwayo muri sisitemu yo gukoresha icyumba cya mudasobwa hamwe na radiyo ntoya igoramye ya kabili optique.

Byinshi byizewe - Umugozi wa optique ntushobora kwibasirwa na electromagnetique kuberako fibre optique ari ubwoko bwa dielectric bushobora gukomeza umurima w'amashanyarazi uhagaze muriwo.Igipimo cyamakosa yibikorwa byo kohereza ibicuruzwa nabyo ni byiza, kandi BER irashobora kugera 10 ^ -15.

Ibibi bya AOC

Inenge nyamukuru ya kabili ya fibre ikora ya AOC ni uko ari igisubizo gihenze cyo guteranya cabling guteranya kubakoresha amakuru menshi.Uretse ibyo, AOC ntishobora kumara igihe kirekire iyo idacunzwe neza kuko yoroshye kandi yoroheje AOC iroroshye cyane kandi yoroheje bigatuma ishobora kwangirika cyane iyo idakozwe neza.

4. Ni ryari ukoresha insinga za AOC?

Nubwo bimeze bityo ariko, intera yohereza hagati ya ToRs nu mpande zifatizo zisanzwe ntiziri munsi ya 100m, aho imiyoboro ihuriweho ikoreshwa cyane.Kubwibyo, insinga ikora ya optique nigisubizo cyiza cyo guhuza amakuru kubera akamaro kayo koroheje, diameter ntoya, hamwe no gufata neza cabling.Kubera ko amakuru yikigo afite ibisobanuro byihariye kubijyanye no kohereza ibimenyetso, umugozi wa optique uruta umugozi wa twin-axe DAC mugutandukanya ibimenyetso no guhuza optique, kugabanya cyane amakosa yo gutunganya ibimenyetso.Ikigeretse kuri ibyo, ibimenyetso bya EMI byihuta cyane bitunganyirizwa mumashanyarazi ya optique, umugozi wa fibre ya AOC ufite imikorere ya EMI nziza kuruta umugozi wa DAC.Nta gushidikanya, umugozi wa AOC nuburyo bwawe bwambere muguhuza hagati yabahinduranya nabahindura mugihe gito cyangwa hagati.

5. Ni ryari Ukoresha insinga za DAC?

Ukurikije imyubakire yimyenda yatangajwe na Facebook, seriveri hamwe na Top-of-Rack switch (ToR) bigize igice cyibanze cyikigo.Muri rusange, intera iri hagati ya ToR na seriveri NIC (Ikarita ya Interineti Ikarita) iri munsi ya metero 5.Muri ibi bihe, umugozi wa DAC urusha inyungu insinga za AOC mubijyanye nigiciro, gukoresha ingufu, no gukwirakwiza ubushyuhe.Rero, DAC nuburyo bwatoranijwe kuri sisitemu yo guhuza IDC.Usibye kandi, mubihe bimwe bidasanzwe, 100G QSFP28 kugeza 4 * SFP28 DAC nubundi buryo butaziguye ukurikije ibyo umukoresha asabwa kugirango ahuze amakuru.
