FAQ
1. Dab tsi yog qhov txawv ntawm 25G SFP28 Passive DAC Direct Txuas Copper Cable thiab fiber ntau optical cable?
A: Qhov sib txawv tseem ceeb yog qhov nruab nrab kis tau tus mob: tooj liab vs. optical fiber. Copper DAC cables feem ntau siv tau ntau dua thiab yooj yim rau kev teeb tsa rau cov ntawv thov luv luv, thaum fiber ntau optical cables siv rau kev ncua ntev thiab tuaj yeem txhawb nqa cov ntaub ntawv ntau dua.
2. Kuv yuav daws teeb meem li cas 25G SFP28 Passive DAC Direct Attach Copper Cable uas tsis ua haujlwm?
A: Pib los ntawm kev txheeb xyuas cov kev sib txuas ntawm ob qhov kawg ntawm lub cable thiab xyuas kom lawv tau zaum zoo. Yog hais tias qhov teeb meem tshwm sim, siv lub cable tester los xyuas qhov txuas ntxiv thiab teeb liab kev ncaj ncees. Tsis tas li ntawd, xyuas seb puas muaj cov cim ntawm kev puas tsuaj lossis hnav ntawm lub cable.
3. Puas yog 25G SFP28 Passive DAC Direct Txuas Copper Cables kub-swappable?
A: Yog lawm, lawv tau tsim los ua kom kub-swappable, tso cai rau koj tshem tawm thiab hloov lawv yam tsis tas yuav siv hluav taws xob hauv lub network. Nws yog ib qho tseem ceeb kom ua raws li cov chaw tsim khoom cov lus qhia kom muaj kev nyab xeeb thiab kho cov txheej txheem kub hloov pauv txhua lub sijhawm.
