[Aipipaton] Kumvetsetsa mawanga asanu ndi atatu mu zingwe za Ethernet: Ntchito ndi machitidwe abwino

640 (2)

Kuphatikiza zingwe zapaintaneti kumatha kusokoneza, makamaka poyesa kudziwa kuti ndi zingwe zamitundu isanu ndi zitatu ziti zofunika kutsimikizira kufalitsa kwa network. Kuti mumvetse bwino izi, ndikofunikira kumvetsetsa ntchito zonsezi: zapangidwa kuti zichepetse kusokonezedwa ndi electromagnetic (EMI) mwa kupotoza awiriawiri pamiyala inayake. Kupotozaku kumalola mafunde a elekitiromaagnetic omwe amatulutsidwa nthawi ya magetsi kuti apatsene wina ndi mnzake, kuchotsa bwino kuthetsa vuto. Mawu oti "opotoza awiri" amalongosola bwino zomanga izi.

Chisinthiko cha awiriawiri

Magulu awiri osindikizidwa omwe adagwiritsidwa ntchito poyambira kutumiza matelefoni, koma kugwira kwawo kunapangitsa kuti akhale ndi zigawo zawo pang'onopang'ono kufala komwe digita. Pakadali pano, mitundu yogwiritsidwa ntchito kwambiri ndi gawo 5e (mphaka 5e) ndi gulu 6 (Mphaka 6) zokhotakhota awiriawiri, onse okhoza kukwaniritsa ma bandwidths mpaka 1000 mbps. Komabe, kukhazikika kwakukulu kwa zingwe zopotoka ndi mtunda wawo wopitilira gawo, zomwe sizimapitirira 100 metres.

Ndikofunika kudziwa kuti kuloweza dongosolo la T568 sikuyenera kupatsidwa kuchuluka kwake kwatha. Ngati pakufunika, mutha kukwaniritsa izi mwa kusintha mawaya 1 ndi 3 ndi 2 ndi 6 kutengera kasinthidwe T568B.

Kusintha kwa maofesi osiyanasiyana

Pazotsatira zoyenera pogwiritsa ntchito gulu 5 ndi gulu la 5e lidapotoza awiriawiri, awiriawiri a mawaya, motero, maaya asanu ndi atatu aliwonse olumikizidwa. Kwa ma network omwe amagwira ntchito pansi pa 100 MBPS, kusinthika kwanthawi zonse kumaphatikizapo kugwiritsa ntchito mawaya 1, 2, 3, ndi 6.

Mu kabatizo wa Ethernet, zokwana zinayi mwa ma cores eyiti (1, 2, 3, ndi 6) amakwaniritsa maudindo potumiza ndi kulandira deta. Ma waya otsala (4, 5, 7, ndi 8) ndi okhazikika ndipo nthawi zambiri amasungidwa mtsogolo. Komabe, mu ma netript opitilira 100 mbps, ndi muyezo kuti mugwiritse ntchito mawaya onse asanu ndi atatu. Pankhaniyi, monga gulu lazingwe 6 kapena pamwamba, pogwiritsa ntchito zigawo zokhazokha zomwe zingayambitse kukhazikika kwa maneti.

Cholinga cha waya aliyense

Kumvetsetsa bwino chifukwa ma waya 1, 2, 3, ndipo 6 akugwiritsidwa ntchito, tiyeni tiwone zofunikira zina mwazomwezi:

Kufunika kwa mapangidwe opindika komanso otetezeka

Atavula chingwe cha Ethernet, mudzazindikira kuti kupindika kwa ma waya kumasiyana kwambiri. Awiriawiri omwe ali ndi vuto la kufalitsa deta - ambiri malalanje ndi obiriwira-obiriwira ambiri mwamphamvu kuposa omwe adagawidwa kuti akhazikitsidwe komanso magawo awiri ofala komanso amtambo. Chifukwa chake, kutsatira mzere wa Ter68B mukangokongoletsa zingwe za chigamba ndikofunikira kuti mugwire bwino.

Maganizo olakwika wamba

Sizachilendo kumva anthu ena, "Ndimakonda kugwiritsa ntchito njira zanga popanga zingwe; ndi zovomerezeka?" Ngakhale kuti pakhoza kugwiritsa ntchito kusintha kwanu panyumba, ndikofunikira kwambiri kutsatira madongosolo owonda mu akatswiri kapena zovuta. Kulowetsa mikhalidwe imeneyi kumatha kusokoneza luso la zingwe zopotoka, zomwe zimapangitsa kuti kufalikira kwa deta ya data ndikuchepetsa kutalikirana.

Mapeto

Mwachidule, ngati mungaganize zokonza mawaya malinga ndi zomwe mumakonda, onetsetsani kuti mwayatsa ma waya 1 ndi atatu limodzi mu awiri opotoka, ndi mawaya 2 ndi 6 m'magulu ena opotoka. Kutsatira malangizowa kuonetsetsa kuti maukonde anu amagwira bwino ntchito moyenera komanso modalirika.
