FAQ
1. Puas yog 100G QSFP28 Passive DAC cable tuaj yeem siv sib hloov nrog lwm cov kev ntsuas ceev, xws li 40G lossis 25G?
A: Tsis yog, 100G QSFP28 Passive DAC cables yog tsim los tshwj xeeb rau 100Gbps daim ntawv thov thiab tsis sib xws nrog cov kev ntsuas qis qis yam tsis muaj kev kho vajtse lossis kev hloov kho raws tu qauv.
2. Dab tsi yog cov ntawv thov rau 100G QSFP28 Passive DAC cables hauv cov chaw khaws ntaub ntawv?
A: Lawv feem ntau yog siv rau high-speed inter-rack lossis intra-rack kev sib txuas nyob rau hauv cov ntaub ntawv chaw, ua kom qis-latency, high-throughput links ntawm servers, cia systems, thiab networking khoom.
3. Puas yog 100G QSFP28 Passive DAC cable txhawb nqa ntau txoj cai lossis nws puas tshwj xeeb rau ib leeg?
A: 100G QSFP28 Passive DAC cables yog tsim los kom muaj ntau yam thiab tuaj yeem txhawb nqa ntau yam kev sib txuas lus, suav nrog Ethernet, InfiniBand, thiab lwm yam, nyob ntawm cov khoom siv thiab kev teeb tsa.
4. Dab tsi yog qhov impedance ntawm 100G QSFP28 Passive DAC cable, thiab vim li cas nws tseem ceeb?
A: Qhov impedance, feem ntau ntsuas hauv ohms, yog qhov tseem ceeb tsis zoo uas cuam tshuam rau lub teeb pom kev cuam tshuam thiab poob. Sib piv cov impedance ntawm lub cable rau cov khoom siv sib txuas ua kom cov teeb liab hloov tau zoo thiab txo qhov kev xav uas tuaj yeem ua rau lub teeb liab degradation.
5. Yuav ua li cas cov tuam txhab kuaj cov kev ua tau zoo ntawm 100G QSFP28 Passive DAC cables kom ntseeg tau tias qhov zoo?
A: D-net ua cov kev xeem nruj, suav nrog lub sij hawm-domain reflectometry (TDR) los ntsuas cable impedance thiab kev cuam tshuam, ntsuas qhov ntsuas me ntsis yuam kev (BERT) txhawm rau ntsuas qhov teeb meem kev ncaj ncees, thiab kev ntsuas kev ntxhov siab ib puag ncig kom ruaj khov nyob rau hauv ntau yam xwm txheej.
