AOC Cablevs DAC Cable: Ndeipi Zvirinani Kwauri

1. Ko DAC neAOC Cables dzinei dzakafanana?
Ose ari maviri eDAC neAOC ndiwo akajairwa macabling mhinduro yedata network uye anowanzo shandiswa kune yakakwirira-kumhanya, yakakwirira-yakavimbika yekubatanidza uye kutapurirana kunodiwa nenzvimbo dzedata, makomputa epamusoro-soro, uye midziyo yekuchengetera yakakura.Ose magumo avo ane tambo magungano ane fekitori-akagumiswa transceivers, ayo akabatana kune akagadziriswa ports chete.Kunze kwezvo, tambo dzeDAC neAOC dzinogona kugadzirwa muhurefu hwakasiyana kuti dzitsigire mazinga akasiyana ekutumira data, akadai se10G SFP DAC/AOC tambo, 25G AOC tambo, 40G DAC tambo, uye 100G AOC tambo.

Zvakawanda Mutengo-Unoshanda- Kazhinji kutaura, mutengo wetambo dzemhangura wakadzikira zvakanyanya pane uya weoptical fibers.Mutengo wetambo tambo dzemhangura wakachipa kaviri kusvika kashanu pane tambo dzefiber dzehurefu hwakafanana.Nokudaro, kushandiswa kwetambo dzepamusoro-soro kuchaderedzawo mari yekombi ye data data yose.

Kushandisa Simba Kuderera- Yepamusoro-inomhanya DAC (yakananga tambo yekubatanidza) inoshandisa simba shoma (simba rekushandisa rinenge razero) sezvo tambo dzepamhepo dzisingadi magetsi.Iko kushandiswa kwesimba kwetambo dzemhangura dzinoshanda kunowanzo kutenderedza 440mW.Kana iwe ukashandisa zvakananga kubatanidza tambo dzemhangura panzvimbo yeAOC fiber tambo, unogona kuchengetedza mazana ezviuru zvekilowatts emagetsi emagetsi.

Iyo inogara yakasimba-Yakagadzirwa iine seamless yekubatanidza fomu ye optical module uye optical tambo, iyo inoderedza mutengo uye inova nechokwadi chekuti optical port haina kuoneswa kuguruva nezvimwe zvinosvibisa.Naizvozvo, DAC hainyanyi kukuvadzwa.

Imwe yezvakaipira yeDAC tambo ndeyekuti inorema uye yakakura kupfuura maAOC.Uye zvakare, inotapurirana nemhedzisiro yekukanganiswa kwemagetsi uye kudzikisira pamusoro pemafaro akareba nekuda kwemasaini emagetsi anofambiswa pakati pemigumo yese.

Kureruka kurema-Iyo inoshanda optical tambo inoumbwa neaviri optical transceivers uye fiber optic chigamba tambo, iyo uremu ingori chikamu chechina cheyakananga tambo yemhangura, uye yakawanda inenge hafu yetambo yemhangura.

Marefu madaro-AOC fiber inogona kupa yakakura uye yakareba kutapurirana kusvika kusvika 100-300m nekuda kwekupisa kwayo kuri nani mukamuri rekombuta wiring system uye diki yekubhenda radius yeoptical cable.

Zvakanyanya Kuvimbika- Active optical tambo haina panjodzi yekukanganiswa kwemagetsi sezvo optical fiber iri rudzi rwe dielectric inogona kuchengetedza static yemagetsi munda mukati mayo.Iyo bit kukanganisa mwero weiyo chigadzirwa chekufambisa kuita iri nani zvakare, uye iyo BER inogona kusvika 10 ^ -15.

Cons yeAOC

Chikanganiso chikuru cheAOC inoshanda fiber tambo ndechekuti inodhura inodhura cabling musangano mhinduro kune yakakwirira-density data center vanoshanda.Kunze kwezvo, maAOC haana kusimba zvakanyanya kana asina kubatwa nemazvo sezvo akareruka uye akatetepa maAOCs akareruka uye akatetepa izvo zvinoita kuti awedzere kukuvara kana akasabatwa nemazvo.

4. Unoshandisa AOC Cables rini?

Zvakangodaro, kureba kwekufambisa pakati peToRs uye edge core switch kazhinji isingasviki 100m, uko Integrated maseketi anoiswa zvakanyanya.Naizvozvo, iyo inoshanda optical tambo iri nani kabling mhinduro yekubatanidza data nekuda kwekukodzera kwayo kwehuremu, diki waya dhayamita, uye inogoneka cabling kugadzirisa.Sezvo dhata data ine zvakaomesesa zvirevo pakufambiswa kwechiratidzo, tambo yemagetsi inoshanda iri nani pane mapatya-ax DAC tambo mukutendeseka kwechiratidzo uye optical coupling dhizaini, ichideredza zvakanyanya zvikanganiso mukugadziriswa kwechiratidzo.Uyezve, iyo yakakwira-frequency EMI siginecha inogadziriswa mukati me pluggable optical modules, AOC fiber tambo ine iri nani EMI kuita pane iyo DAC tambo.Pasina kupokana, AOC tambo ndiyo yako yekutanga sarudzo mukubatana pakati pekuchinja uye switch mukati menguva pfupi kana yepakati kusvika.

5. Unoshandisa DAC Cables riini?

Zvinoenderana neyakavakwa machira yakaziviswa neFacebook, sevha uye Yepamusoro-ye-Rack switch (ToR) inoumba chikamu chakakosha che data data.Kazhinji kutaura, chinhambwe chiri pakati peToR neseva NIC(Network Interface Card) isingasviki 5 metres.Mumamiriro ezvinhu aya, tambo yeDAC inobatsira kupfuura tambo dzeAOC maererano nemutengo, mashandisiro emagetsi, uye kuparadzira kupisa.Nekudaro, DAC isarudzo yakasarudzika yeIDC yekubatanidza masisitimu.Kunze kwezvo, pane dzimwe nguva dzakakosha, 100G QSFP28 kusvika 4 * SFP28 DAC ndiyo imwe nzira yakananga yekubatanidza zvinoenderana nezvinodiwa nemushandisi zvekubatanidza data.
