Dab tsi yog qhov txawv ntawm Ca5e, Cat6, thiab Cat7? Qeb Tsib (CAT5): Cov zaus kis tau tus mob yog 100MHz, siv rau lub suab kis tau tus mob thiab cov ntaub ntawv kis tau tus mob nrog lub siab tshaj plaws kis tau tus mob ntawm 100Mbps, feem ntau yog siv nyob rau hauv 100BASE-T thiab 10BASE-T tes hauj lwm. Qhov no...

1 * 9 ntim cov khoom siv kho qhov muag yog thawj zaug hauv xyoo 1999. Nws yog cov khoom lag luam kho qhov muag kho qhov muag. Nws yog feem ntau ncaj qha kho (soldered) ntawm lub rooj tsav xwm Circuit Court ntawm cov khoom siv sib txuas lus thiab siv los ua ib qho kho qhov muag module. Qee lub sij hawm nws tseem hu ua ...

1. Cov qib ua haujlwm sib txawv: Txheej 2 hloov pauv ua haujlwm ntawm cov ntaub ntawv txuas txheej, thiab Txheej 3 hloov pauv ua haujlwm ntawm txheej txheej network. Txheej 3 hloov tsis tau tsuas yog ua tiav high-speed forwarding ntawm cov ntaub ntawv packets, tab sis kuj ua tau zoo network kev ua tau zoo raws li qhov sib txawv ...

Peb lub teb chaws xov tooj optical transceivers tau tsim sai heev nrog kev txhim kho ntawm kev soj ntsuam kev lag luam. Los ntawm analog mus rau digital, thiab tom qab ntawd los ntawm digital mus rau cov ntsiab lus siab, lawv tau nce mus tas li. Tom qab xyoo ntawm kev sib sau ua ke, lawv muaj ...

Nrog rau txoj kev loj hlob ntawm kev lag luam kev sib txuas lus thiab cov ntaub ntawv qhia txog kev lag luam hauv lub tebchaws, kev tswj hwm lub nplhaib hloov pauv kev lag luam tau loj hlob tsis tu ncua. Nws yog tus nqi-zoo, hloov tau yooj yim, kuj yooj yim thiab siv tau yooj yim. Ethernet Technology H...

Kev ua haujlwm ntawm fiber ntau optic transceivers yog hloov pauv ntawm cov teeb liab kho qhov muag thiab cov teeb liab hluav taws xob. Cov teeb liab kho qhov muag yog tawm tswv yim los ntawm qhov chaw nres nkoj kho qhov muag, thiab cov teeb liab hluav taws xob yog qhov tso tawm los ntawm qhov chaw nres nkoj hluav taws xob, thiab lwm yam. Cov txheej txheem yog roughly li rau ...
