Kodi DAC Copper Kapena Fiber?

Kodi DAC Copper kapena Fiber?
Zingwe za DAC zimapangidwa kuchokera ku Twinax coaxial coaxial ndipo zimakhala ndi ma module mbali zonse zolumikizidwa ndi madoko osakhazikika.Ma modules sangathe kuchotsedwa pa chingwe.Chifukwa chake, zingwe zonse za DAC zimapangidwa motalika.Chingwe chamkuwa chothamanga kwambiri chimakhala ndi magwiridwe antchito abwino kwambiri, latency yotsika, komanso anti-kusokoneza pamayendedwe othamanga kwambiri.

Kodi Twinax Cable Imagwiritsidwa Ntchito Bwanji?
Chingwe cholumikizidwa mwachindunji cha Twinax chingagwiritsidwe ntchito kwambiri polumikizana ndi data center monga zida zosungira SATA, makina a RADI, ma routers apakatikati, ma switch switch, ma seva a 10G/40G/100G Ethernet, ndi InfiniBand.Nthawi zambiri, chingwe cholumikizira chamkuwachi chimapereka njira yotsika mtengo komanso yogwira ntchito kwambiri pazotsatirazi:
• Pamwamba pa Rack(ToR)/Adjacent Rack - Chingwe chokhazikika kapena chogwira ntchito cha DAC ndichabwino kwa ToR kapena ma rack-to-rack omwe ali ndi ndalama zotsika mtengo.
• Pakati pa Mzere - Ma DAC Ogwira ntchito angakhale njira yabwino yothetsera vutoli, bola ngati mtunda wotumizira ndi wosakwana 15m.
• Mapeto a Row - Zingwe za DAC ndizoyenera kumapeto kwa mizere yomanga malinga ngati mtunda uli mkati mwa malire a mamita 15.

Kodi Pali Kusiyana Kotani Pakati pa Ma Cable A Active Ndi Passive DAC?
Kusiyana kwakukulu pakati pa chingwe chogwira ntchito cha DAC ndi chingwe cha DAC chokhazikika ndikuti ngati kusinthidwa kwa siginecha kwachitika kapena ayi.Ngati pali gawo lamagetsi lowongolera ma siginecha mu chingwe, ndi "Active DAC".Ngati sichoncho, ndi "Passive DAC", chifukwa sichigwiritsa ntchito zamagetsi pakuwongolera ma siginecha.Kupatula gawo lamkati, zingwe zogwira ntchito komanso zopanda pake za DAC zimasiyananso wina ndi mnzake muutali wa ulalo.Chingwe chokhazikika cha DAC Twinax chimatumiza chizindikiro cha Efaneti kutalika kwaufupi (0.5 m-5 m), pomwe chingwe chogwira ntchito cha DAC Twinax chimathandizira mtunda wotumizira wa 5 m-10 m kwa chizindikiro cha Efaneti.
