Raws li peb txhua tus paub, Gigabit Ethernet keyboards feem ntau muaj ob hom chaw nres nkoj: RJ45 chaw nres nkoj thiab SFP chaw nres nkoj. Ob hom chaw nres nkoj tuaj yeem nqa Gigabit Ethernet kis tau tus mob, yog li dab tsi yog qhov txawv ntawm lawv? Dab tsi ntawm qhov chaw nres nkoj Gigabit Ethernet hloov yuav tsum tau siv kom paub txog Gigabit Ethernet kev twb kev txuas?

Dab tsi yog qhov chaw nres nkoj RJ45 ntawm Gigabit Ethernet hloov?
Qhov chaw nres nkoj RJ45 ntawm Gigabit Ethernet hloov yog qhov chaw nres nkoj built-in. Hom chaw nres nkoj no tuaj yeem siv rau kev nkag mus rau cov neeg rau zaub mov hauv cov ntaub ntawv chaw, LAN, thiab uplink ntawm desktop keyboards lossis Gigabit rau desktop bandwidth applications. Thaum ob lub Gigabit Ethernet keyboards txuas nrog, cov qauv sib tw-pair cables feem ntau yog siv, xws li CAT-5, CAT-5, CAT-6, thiab CAT-6 network jumpers

Dab tsi yog qhov chaw nres nkoj SFP ntawm Gigabit Ethernet hloov?

SFP chaw nres nkoj (me me kub-swappable interface) tseem hu ua mini-GBIC chaw nres nkoj, tus nqi kis tau tus mob yog 1G, thiab nws tuaj yeem txhawb kev txuas tooj liab lossis qhov txuas txuas (hauv Ethernet, SFP chaw nres nkoj tus nqi yog 1Gbit / s, hauv fiber ntau channel hauv, SFP chaw nres nkoj tus nqi tuaj yeem ncav cuag 4Gbit / s). Thaum muab cov khoom siv hluav taws xob txuas rau hauv qhov chaw nres nkoj SFP, nws feem ntau txuas nrog lub network cable (Cat5 / Cat5e / Cat6) rau cov ntaub ntawv xa mus. Thaum qhov chaw nres nkoj kho qhov muag tau muab tso rau hauv qhov chaw nres nkoj SFP, koj yuav tsum siv LC jumper kom xa mus rau kom ua tiav kev sib kis ntev dua. Tsis tas li ntawd, hauv cov ntawv thov xws li cov chaw khaws ntaub ntawv thiab cov chaw hauv cheeb tsam hauv cheeb tsam (LAN), qhov hloov pauv qhov chaw nres nkoj SFP kuj tseem muaj 100/1000Mbps hloov ua haujlwm.

RJ45 chaw nres nkoj VS SFP chaw nres nkoj

Los ntawm qhov pom saum toj no, qhov ua tau zoo ntawm RJ45 chaw nres nkoj thiab SFP chaw nres nkoj yog qhov zoo ib yam; tab sis los ntawm tus nqi ntawm qhov pom, tus nqi xaim ntawm SFP chaw nres nkoj yog siab dua. Txawm li cas los xij, SFP chaw nres nkoj tseem tsim nyog vim tias nws tuaj yeem txhawb nqa ob hom SFP hluav taws xob chaw nres nkoj modules thiab SFP optical port modules. Thaum siv SFP optical chaw nres nkoj optical modules, qhov kev sib kis deb kuj ntev dua li ntawm RJ45 cov chaw nres nkoj. Hauv kev siv cov tswv yim, nws muaj qhov hloov pauv tau yooj yim, thiab scalability kuj tseem siab.
