AOC Cablevs DAC Cable: Zomwe zili Zabwino kwa Inu

1. Kodi Ma Cable a DAC ndi AOC Amagwirizana Bwanji?
Onse a DAC ndi AOC ndi njira zodziwika bwino za ma cabling pa intaneti ndipo nthawi zambiri amagwiritsidwa ntchito polumikizana mwachangu, kudalirika kwambiri komanso kutumiza komwe kumafunikira ndi malo opangira ma data, makompyuta ochita bwino kwambiri, ndi zida zazikulu zosungira.Mapeto awo onse ali ndi misonkhano ya zingwe yokhala ndi ma transceivers omwe amathetsedwa ndi fakitale, omwe amalumikizidwa ndi madoko okhazikika okha.Kupatula apo, zingwe za DAC ndi AOC zimatha kupangidwa motalika mosiyanasiyana kuti zithandizire ma data osiyanasiyana otumizira, monga chingwe cha 10G SFP DAC/AOC, chingwe cha 25G AOC, chingwe cha 40G DAC, ndi chingwe cha 100G AOC.

2. Ubwino ndi kuipa kwa DAC Cable

Ubwino wa Direct Attach Copper Cable

Zotsika mtengo- Nthawi zambiri, mtengo wa zingwe zamkuwa ndi wotsika kwambiri kuposa wa ulusi wa kuwala.Mtengo wa zingwe zamkuwa zokhazikika ndi 2 mpaka 5 zotsika mtengo kuposa zingwe za fiber zautali womwewo.Choncho, kugwiritsa ntchito zingwe zothamanga kwambiri kudzachepetsanso mtengo wa cabling wa data center yonse.

Kugwiritsa Ntchito Mphamvu Zotsika - Kuthamanga kwambiri kwa DAC (chingwe cholumikizira mwachindunji) kumawononga mphamvu zochepa (kugwiritsira ntchito mphamvu kumakhala pafupifupi ziro) popeza zingwe zongokhala sizifuna magetsi.Kugwiritsa ntchito mphamvu kwa zingwe zamkuwa zogwira ntchito nthawi zambiri kumakhala pafupifupi 440mW.Ngati mumagwiritsa ntchito zingwe zamkuwa zachindunji m'malo mwa zingwe za AOC, mutha kupulumutsa mazana masauzande amagetsi amagetsi.

Ndiwolimba kwambiri-Idapangidwa ndi mawonekedwe olumikizira opanda msoko a module ya optical ndi chingwe chowunikira, chomwe chimachepetsa mtengo ndikuwonetsetsa kuti doko loyang'ana silimawonekera ku fumbi ndi zoipitsa zina.Chifukwa chake, DAC ndiyosavuta kuwonongeka.

 Kuipa kwa Direct Attach Copper Cable

Chimodzi mwazovuta za chingwe cha DAC ndikuti ndi cholemera komanso chokulirapo kuposa ma AOC.Kuphatikiza apo, imakhala pachiwopsezo cha kusokonezedwa ndi ma elekitiroma komanso kuchepa kwa mtunda wautali chifukwa cha ma siginecha amagetsi omwe amaperekedwa pakati pa mbali zonse ziwiri.

3. Ubwino ndi kuipa kwa AOC Cable

Ubwino wa AOC

Kulemera kopepuka-Chingwe chogwira ntchito chimapangidwa ndi ma transceivers awiri owoneka bwino ndi chingwe cha fiber optic patch, chomwe kulemera kwake ndi kotala la chingwe chamkuwa cholunjika, ndipo chochuluka chake ndi theka la chingwe chamkuwa.

Mitali yayitali-Chingwe cha AOC chikhoza kupereka kufalikira kwakukulu komanso kotalikirapo mpaka 100-300m chifukwa cha kutentha kwake kwabwino mu makina opangira mawaya apakompyuta komanso utali wopindika wa chingwe chowonera.

Chodalirika Kwambiri- Chingwe chowoneka bwino sichikhala pachiwopsezo cha kusokonezedwa ndi ma elekitiroma chifukwa kuwala kwa fiber ndi mtundu wa dielectric womwe ungathe kusungitsa malo amagetsi osasunthika mkati mwake.Kulakwitsa pang'ono kwa ntchito yotumizira zinthu ndikwabwinoko, ndipo BER imatha kufika 10 ^ -15.

Zotsatira za AOC

Choyipa chachikulu cha zingwe za AOC zogwira ntchito ndikuti ndi njira yolumikizirana yokwera mtengo kwambiri kwa ogwiritsira ntchito ma data apakati.Kupatula apo, ma AOC sakhala olimba ngati sakuyendetsedwa bwino chifukwa ndi opepuka komanso owonda ma AOCs ndi opepuka komanso ocheperako zomwe zimawapangitsa kuti aziwonongeka kwambiri ngati sizikugwiridwa bwino.

4. Kodi AOC Cables mumagwiritsa ntchito liti?

Komabe, mtunda wotumizira pakati pa ma ToR ndi masiwichi am'mphepete nthawi zambiri umakhala wosakwana 100m, pomwe mabwalo Ophatikizidwa amayikidwa mochuluka.Chifukwa chake, chingwe chogwira ntchito ndi njira yabwinoko yolumikizira deta chifukwa cha kupepuka kwake, waya wocheperako, komanso kukonza ma cabling.Popeza malo osungiramo data ali ndi mfundo zokhwima pa kutumiza ma siginecha, chingwe chogwira ntchito ndi chabwino kuposa chingwe cha DAC cha mapasa-ax mu kukhulupirika kwa chizindikiro ndi mawonekedwe olumikizirana, kumachepetsa kwambiri zolakwika pakukonza ma siginecha.Kuphatikiza apo, chizindikiro cha EMI chokwera kwambiri chimasinthidwa mkati mwa ma module opangidwa ndi pluggable, chingwe cha AOC fiber chili ndi magwiridwe antchito a EMI kuposa chingwe cha DAC.Mosakayikira, chingwe cha AOC ndiye njira yanu yoyamba pakulumikizana pakati pa masinthidwe ndi masinthidwe mkati mwanthawi yayitali kapena yapakatikati.

5. Kodi mumagwiritsa ntchito liti zingwe za DAC?

Malinga ndi kapangidwe kansalu kolengezedwa ndi Facebook, seva ndi ma switch a Top-of-Rack(ToR) amapanga gawo loyambira la data center.Nthawi zambiri, mtunda wapakati pa ToR ndi seva NIC(Network Interface Card) ndi wochepera 5 metres.Zikatero, chingwe cha DAC ndichothandiza kwambiri kuposa zingwe za AOC pankhani ya mtengo, kugwiritsa ntchito mphamvu, komanso kufalikira kwa kutentha.Chifukwa chake, DAC ndi njira yabwino yolumikizirana ndi IDC.Kupatula apo, nthawi zina zapadera, 100G QSFP28 mpaka 4 * SFP28 DAC ndi njira ina yolumikizira mwachindunji malinga ndi zomwe wogwiritsa ntchito akufuna kuti alumikizane ndi data.
