Qhov ntev tshaj plaws ntawm Ethernet cable: nws tuaj yeem yog dab tsi?

Qhov ntev tshaj plaws ntawm cable ethernetYuav yog tus twg?
Txoj cai kub rau cov cables Ethernet tooj liab txheem (xws li Cat5e, Cat6 thiab miv6a) yog 100 meters (328 feet). Qhov ntev tshaj plaws no suav nrog tag nrho cov channel: qhov tseem ceeb ntawm cov cable ntxiv rau cov cables luv dua ntawm txhua qhov kawg.

Vim li cas ho txwv 100m?
Dhau qhov kev ncua deb no, cov teeb liab hluav taws xob uas hla cov xov tooj liab yuav qaug zog heev vim yog qhov txo qis. Kev cuam tshuam (crosstalk) thiab teeb meem sib dhos teeb liab kuj ua teeb meem. Tshaj 100 meters feem ntau ua rau qeeb qeeb, sib txuas tsis tu ncua, lossis ua tsis tiav tag nrho.

Xav tau mus ntxiv? Koj muaj cov kev xaiv:

Cov hloov pauv network/hubs: Tso ib lub cuab yeej uas siv tau, xws li lub hloov lossis hub, ua ntej lub cim 100m pib dua qhov ntsuas qhov deb. Qhov no tso cai rau koj txuas cov ntu sib txuas ua ke (txhua

Cov khoom siv txuas Ethernet: Cov khoom siv tshwj xeeb no hloov cov teeb liab rau kev xa mus rau qhov deb dua, qee zaum siv cov cabling sib txawv, xws li coaxial cable lossis DSL kab, uas tuaj yeem ncav cuag kilometers. Cov cables fiber optic: Rau qhov ntev heev (pua pua meters lossis txawm tias kilometers) thiab kev ua tau zoo dua, cov cables fiber optic yog qhov kev daws teeb meem zoo tshaj plaws, txawm hais tias lawv xav tau cov transceivers sib xws ntawm txhua qhov kawg.
