Ngaba iDAC iCopper okanye iFayibha?
Iintambo zeDAC zenziwe kwi-Twinax coaxial yobhedu ekhuselweyo kwaye ifaktri ixhotyiswe ngeemodyuli macala omabini aqhagamshelwe kumazibuko asisigxina.Iimodyuli azikwazi ukususwa kwikhebula.Ke ngoko, zonke iintambo zeDAC ziveliswa kubude obumiselweyo.Intambo yobhedu enesantya esiphezulu inomsebenzi oncomekayo wokuthomalalisa, i-latency ephantsi, kunye nokuchasana nokuphazamiseka kwi-high-frequency broadband transmission.
Isetyenziselwa ntoni iCable yeTwinax?
Intambo ye-Twinax eqhotyoshelwe ngokuthe ngqo ingasetyenziselwa ngokubanzi kwi-interconnection center data ezifana nezixhobo zokugcina ze-SATA, iinkqubo ze-RADI, ii-routers eziphambili, ii-switch switches, iiseva ze-10G / 40G / 100G Ethernet, kunye ne-InfiniBand.Ngokubanzi, le ntambo yobhedu encamathele ngokuthe ngqo ibonelela ngesisombululo esineendleko eziphezulu kunye nokusebenza okuphezulu kwezi meko zilandelayo:
• Umphezulu weRakhi (ToR)/iRakhi eYameneyo – Nokuba intambo ye-DAC esebenzayo okanye esebenzayo igqibelele kwi-ToR emfutshane okanye i-rack-to-rack imisebenzi enohlahlo lwabiwo-mali olusebenzayo.
• Umbindi woMqolo – IiDAC ezisebenzayo zingasisisombululo esingcono kwesi sicelo, ukuba umgama wothumelo ungaphantsi kwe-15m.
• Ukuphela komqolo – iintambo zeDAC zilungele ukuphela koyilo lwezakhiwo ukuba nje umgama ungaphakathi kweemitha ezili-15.
Yintoni Umahluko phakathi kweeCables zeDAC eziSebenzayo kunye nePassive?
Umahluko omkhulu phakathi kwentambo ye-DAC esebenzayo kunye nentambo ye-DAC esebenzayo kukuba ingaba inkqubo yesiginali yenziwe okanye hayi.Ukuba kukho inxalenye yombane yokulungiswa komqondiso kwintambo, yi-"Active DAC".Ukuba akunjalo, yi-"Passive DAC", kuba ayisebenzisi izixhobo zombane ukulungiselela ukumiswa komqondiso.Ngaphandle kwecandelo elingaphakathi, iintambo ze-DAC ezisebenzayo kunye ne-passive nazo ziyahluka omnye komnye ngobude bekhonkco.Intambo ye-DAC ye-Twinax ye-passive idlulisela isibonakaliso se-Ethernet ngobude obufutshane (0.5 m-5 m), ngelixa i-DAC esebenzayo intambo ye-Twinax isekela umgama wothumelo we-5 m-10 m kwisignali ye-Ethernet.
