Mphamvu pa Ethernet (ndakatulo) ukadaulo wasintha momwe timatengera zida za network polola mphamvu ndi deta kuti ifalitsidwe pa ethernet. Komabe, ogwiritsa ntchito ambiri amadabwa kuti mtunda wokwera kwambiri wopita kubwali. Kumvetsetsa zinthu zomwe zimapangitsa mtunda uwu ndikofunikira kuti pakhale ma network kukonzekera ndi kuphedwa.

Kodi chimapangitsa mtunda waukulu wa ndakatulo?

Chovuta pakusankha mtunda wokwanira pabwalo ndi mtundu ndi mtundu wa bata wopotoza womwe wagwiritsidwa ntchito. Miyezo yodziwika bwino imaphatikizapo:

Shanghai-Aipi-Waton-Electronic-Fakiliya-Co-Ltd-

Gulu 5 (Mphaka 5)

Imathandizira kuthamanga mpaka 100 mbps

Gawo 5e (Mphaka 5e)

Mtundu wowonjezera ndi luso labwino, komanso kuchirikiza 100 bps.

Gulu 6 (Mphaka 6)

Imatha kuthana ndi liwiro mpaka 1 Gbps.

Mosasamala kanthu za chingwe, miyezo yamakampani imakhazikitsa gawo lokwanira kwambiri kwamita mita (mapazi 328) pazolumikizira za Ethernet. Izi ndizofunikira kuti tisunge umphumphu ndi kukhulupirika kwa data ndikuwonetsetsa maulalo odalirika.

Sayansi Yoyambitsa Mita 100

Pakadutsa zizindikiro, zingwe zopindika zopotoka zimatsutsana ndi kuchuluka, zomwe zimatha kuwonongeka. Monga Tsitsani Chizindikiro Chosatha, Itha Kutanthauzira:

CHITSANZO:

Kutayika kwa mphamvu yakuimira patali.

Lakwitsidwa:

Kusintha kwa mawonekedwe a siginecha, kumakhudza kukhulupirika kwa data.

Mtundu wa chizindikiro chikamachepa kupitirira, kumakhudzanso kuchuluka kwa kufalitsa kothandiza ndipo kumatha kuyambitsa kuchepa kwa deta kapena zolakwa za packe.

Kuwerengera kutali

Kwa 100base-TX, yomwe imagwira ntchito pa 100 mbps, nthawi yofalitsa deta imodzi, yotchedwa "nthawi yochepa," imawerengedwa motere:

[\ mafoni {nthawi ya nthawi} = \ frac {1} {100, \ \ \ \ \ \ \}}}} = 10, \ \ {\ \}]

Njira yotumizira iyi imagwiritsa ntchito CSMA / CD (kunyamula ndalama zambiri popezeka ndi kupezeka kwagy), kulola kuti pakhale kuwunikira koyenera kwa maukonde ogawana. Komabe, ngati kutalika kwa chingwe kumapitilira 100 metres, mwayi wofufuza kuti kuwombana kumachepetsa, kutayika kwa data.

Ndikofunikira kudziwa kuti kutalikirana kwakukulu kumakhazikitsidwa pa mita 100, zinthu zina zimatha kulola kusinthasintha. Mwachitsanzo, kuthamanga kwam'munsi, kungakulitse mtunda wautali mpaka 150-200 metres, kutengera chingwe chabwino ndi maukonde.

Malangizo othandiza okwanira

Mu kukhazikitsa zenizeni padziko lapansi, kutsatira malire a mita 100 ndikofunikira. Komabe, akatswiri ambiri pa intaneti amalimbikitsa kuti azikhala mtunda wa mamita 80 mpaka 90 kuti atsimikizire kudalirika ndikuchepetsa zovuta zilizonse. Mbali yachitetezo ichi imathandizira kugwiritsira ntchito mitundu yazithunzi komanso malo okhazikitsa.

Ngakhale zingwe zapamwamba zimatha kupitirira 100 malire malire osamba kwambiri, njirayi siyibwino. Mavuto omwe angakhalepo atakhala pakusokoneza kwa nthawi, kumapangitsa kuti pakhale kusokonezeka kwakukulu kwa intaneti kapena magwiridwe antchito okwanira pambuyo pokonza.

Mapeto

Kuti mumvenso mwachidule, mtunda wokwera kwambiri wamaukadaulo wa ndakatulo makamaka amakhudzidwa ndi gulu la zingwe zopotoka ndi zofooka zakuthupi za kufalikira. Malire a mita 100 amakhazikitsidwa kuti athandize kukhalabe ndi umphumphu ndi kudalirika. Potsatira dongosolo lolimbikitsira ndi kumvetsetsa zofunikira za Ethernet, zomwe zimachitika pa intaneti zitha kuwonetsetsa kuti ma network apanyumba amayenda bwino.
