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 cov 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 ...

IEEE 802.3 yog dab tsi? IEEE 802.3 yog ib pab pawg ua haujlwm uas tau sau lub koom haum ntawm Hluav Taws Xob thiab Hluav Taws Xob Hluav Taws Xob (IEEE) tus qauv txheej txheem, uas txhais tau hais tias kev nkag mus tau nruab nrab (MAC) ntawm ob lub cev thiab cov ntaub ntawv txuas cov khaubncaws sab nraud povtseg ntawm wired Ethernet. Qhov no feem ntau yog ib ...

Optical fiber transceiver yog ib qho khoom siv zoo heev thiab hloov tau yooj yim. Kev siv ntau yog los hloov cov teeb liab hluav taws xob hauv cov sib tw twisted rau hauv cov teeb liab optical. Nws feem ntau yog siv hauv Ethernet tooj liab cables uas tsis tuaj yeem npog thiab yuav tsum siv cov fibers kho qhov muag rau ...

Ring network redundancy yog dab tsi? Lub nplhaib network siv lub nplhaib txuas txuas txuas mus rau txhua lub cuab yeej ua ke. Nws ua kom ntseeg tau tias lub teeb liab xa los ntawm ib lub cuab yeej tuaj yeem pom los ntawm txhua yam khoom siv ntawm lub nplhaib. Lub nplhaib network redundancy yog hais txog seb qhov hloov pauv ...

Network Topology Network topology yog dab tsi yog hais txog lub cev layout nta xws li lub cev kev sib txuas ntawm ntau yam kev sib kis xov xwm, network cables, thiab abstractly tham txog kev sib cuam tshuam ntawm ntau yam kawg hauv lub network system los ntawm kev qiv cov ...

STP yog dab tsi? STP (Spanning Tree Protocol) yog kev sib txuas lus raws tu qauv uas ua haujlwm ntawm txheej thib ob (cov ntaub ntawv txuas txheej) hauv OSI network qauv. Nws daim ntawv thov yooj yim yog los tiv thaiv loops tshwm sim los ntawm redundant txuas hauv keyboards. Nws yog siv los xyuas kom meej tias muaj ...

Dab tsi yog cua daj cua dub tshaj tawm? Cov cua daj cua dub tshaj tawm tsuas yog txhais tau hais tias thaum cov ntaub ntawv tshaj tawm dej nyab lub network thiab tsis tuaj yeem ua tiav, nws siv ntau lub network bandwidth, ua rau tsis muaj peev xwm ntawm cov kev pabcuam ib txwm khiav, lossis txawm tias ua tiav tuag tes tuag taw ...

Optical fiber ntau transceiver yog Ethernet kis tau tus mob media conversion unit uas interchanges luv luv twisted-pair hluav taws xob signals thiab ntev-ntev optical signals. Nws tseem hu ua fiber ntau converter nyob rau hauv ntau qhov chaw. Cov khoom siv feem ntau yog siv hauv ...

(1) Tsis tau muaj dhau los siab bandwidth. Tus nqi ntawm GPON yog siab li 2.5 Gbps, uas muaj peev xwm muab ib tug loj txaus bandwidth kom tau raws li qhov kev thov loj hlob rau siab bandwidth nyob rau hauv lub neej yav tom ntej network, thiab nws asymmetric yam ntxwv yuav zoo dua hloov mus rau broadband cov ntaub ntawv se ...
