DAC ma Copper mise Fiber?

DAC ma Copper mise Fiber?
Xadhkaha DAC waxay ka samaysan yihiin gaashaanka Twinax copper coaxial waana warshad ku qalabaysan qaybo ka mid ah labada daraf ee ku xidhan dekedaha go'an.Qaybaha lagama saari karo fiilada.Sidaa darteed, dhammaan fiilooyinka DAC waxaa lagu soo saaraa dherer go'an.Xawaare sare oo naxaas ah ayaa leh wax-qabad aad u wanaagsan, daahitaan hooseeya, iyo ka-hortagga ka-hortagga gudbinta xawaaraha sare ee ballaadhan.

Waa maxay Cable-ka Twinax loo isticmaalo?
Fiilada Twinax ee tooska ah ee tooska ah ayaa si weyn loogu isticmaali karaa isku xirka xarunta xogta sida aaladaha kaydinta SATA, nidaamyada RADI, jiheeyayaasha asaasiga ah, furayaasha muhiimka ah, adeegayaasha 10G/40G/100G Ethernet, iyo InfiniBand.Guud ahaan, xadhigga naxaasta ah ee sida tooska ah ugu xidhan waxa uu bixiyaa xal kharash-ku-ool ah oo wax-qabad sare leh xaaladaha soo socda:
• Sarka sare ee Rack(ToR)/Rack ku xiga - Ama fiilo DAC ah oo aan fiicneyn ama firfircooni waxay ku fiican tahay ToR gaaban ama hawlgallada rack-to-rack oo leh miisaaniyado kharash-ool ah.
• Dhexe ee safka - DAC-yada firfircoon ayaa laga yaabaa inay xal fiican u yihiin codsigan, ilaa inta fogaanta gudbintu ay ka yar tahay 15m.
• Dhamaadka safka - Xadhkaha DAC waxay ku habboon yihiin dhamaadka qaab-dhismeedka safafka ilaa inta masaafada ay ku jirto xadka 15 mitir.

Waa maxay faraqa u dhexeeya fiilooyinka DAC ee fir fircoon iyo kuwa dadban?
Farqiga ugu weyn ee u dhexeeya fiilada DAC ee firfircoon iyo fiilada DAC ee aan tooska ahayn waa haddii farsamaynta calaamadaha la sameeyay iyo in kale.Haddii ay jirto qayb koronto oo loogu talagalay qaboojinta calaamadaha fiilada, waa "DAC firfircoon".Haddaysan ahayn, waa “Passive DAC”, maadaama aysan ku habboonayn qalabka elektiroonigga ah ee qaboojinta calaamadaha.Marka laga reebo qaybta gudaha, fiilooyinka DAC ee firfircoon iyo kuwa aan fiicneyn waxay sidoo kale ku kala duwan yihiin midba midka kale dhererka isku xirka.Fiilada DAC Twinax ee dadban waxay gudbisaa signalka Ethernet dherer gaaban (0.5 m-5 m), halka fiilada DAC Twinax ee firfircoon ay taageerto fogaanta gudbinta ee 5 m-10 m ee calaamadda Ethernet.
