Apo iwe (kana kuti yako basa) unoda kambo yekaseka
Nhare yekaseka, dzimwe nguva inonzi yakayambuka kambo , inobatanidza zvinhu zviviri zveEthernet zvigadzirwa kune mumwe nemumwe. Izvo zvakasikwa kuti zvitsigire nguva shomanana-ye-host network mumamiriro ezvinhu apo chimbo chepakati chakafanana se network network haisipo.
Crossover cables inotarisa yakafanana neyemazuva ose, yakananga kuburikidza (kana patch ) Ethernet cables kusvikira mukati mawo wiring structures akaenzaniswa.
Crossover vs Straight Through Cable
Rimwe karoti yakasarudzika, inoshandiswa kuunganidza maitiro akasiyana-siyana emashandisirwo pamwe chete, sekombiyuta kune network network. Dhavha yekaseka inopesana - inobatanidza zvinhu zviviri zvechimiro chakafanana.
Chigadziko chemakumbo emakumbo chinogona kusvibiswa chero ipi zvayo kana nguva dzose dzese dzichifanana. Kuenzaniswa kurudyi kuburikidza nemakambani eEthernet, wiring yechipfuva yekaseka inoshandura inotumira uye inogamuchira zviratidzo.
Iyo inoshandiswa mavara-coded wires inogona kuonekwa kuburikidza ne -RJ-45 connectors pamagumo ose emucheche:
- Mitsara yakafanana ine kuenzana kwakafanana kwemavara akaonesa pamagumo ose
- Crossover mitsara ine yekutanga uye yechitatu mahwindo (kuverenga kubva kuruboshwe kuenda kurudyi) akayambuka, uye wechipiri uye yechitanhatu tambo dzakayambuka
A good Ethernet crossover cable ichave yakarongedzwa zvakananga kuti iparadzanise kubva kune yakananga kuburikidza neyo. Vakawanda vatsvuku muvara uye vanove ne "crossover" yakagadziriswa pamapurasitiki nematareji.
Unoda Crossover Cable?
Crossover tambo dzaiwanzoshandiswa neRuzivo Technology (IT) vadzidzisi mumakore ekuma1990 nema2000 kubvira apo maitiro akakurumbira eEthernet panguva iyoyo haana kutsigira zvakananga cable connections pakati pevanhu.
Zvose izvo zvakasikwa uye Fast Ethernet mitemo yakagadzirirwa kushandiswa michina yakananga yekutumira uye kugamuchira zviratidzo. Iyi mitemo yaida kuti magumo maviri asvike pakukurukurirana kuburikidza nechigadzirwa chepakati pekudzivisa kusagadzikana kubva kuedza kushandiswa nematairi akafanana ekutumira uye kugamuchira.
Chimwe chinhu cheEthernet chinonzi MDI-X chinopa rubatsiro runodikanwa rwekutsvaga kwekudzivirira kuchengetedza zviratidzo izvi. Iyo inobvumira Ethernet interface kuti iongorore kuti chii chinoratidza kugadziriswa kwechigadzirwa pane imwe mugumo weyanzvi dzetambo uye inokurukura kushandiswa kwekutumira nekugamuchira mafaira maererano. Cherechedza kuti rimwe chete kuguma kwekubatana kunoda kutsigira kuzvitsvaga kwechiitiko ichi kushanda.
Migwagwa yakawanda yemisha yakawanda yepamusha (kunyange mienzaniso yakare) inosanganisira MDI-X rubatsiro pavanoshandisa Ethernet interfaces. Gigabit Ethernet yakagamuchirawo MDI-X seyero.
Crossover cables inongoda chete kana ichibatanidza majekiti maviri Ethernet maklayiti apo hapana yakagadzirirwa Gigabit Ethernet. Mazuva ano Ethernet zvishandiso zvino zvinozviona zvakananga kushandiswa kwetambo dze crossover uye kushanda navo zvisina kusimba.
Nzira yekushandisa Ethernet Crossover Cables
Crossover cables inofanira kungoshandiswa chete zvakananga network connections. Nokuda kwechikonzero chinotsanangurwa pamusoro apa, kuedza kubatanidza kombiyuta kune rekare router kana kushanduka kwekambani nekambo yepasta panzvimbo yemutambo wakajairika, inogona kudzivirira kubatana kushanda.
Tsamba idzi dzinogona kutengwa zvakananga kuburikidza nemichina yakasiyana-siyana yemagetsi. Hobbyists nevamwe vashandi veIt IT vanogona kusarudza kuita zvigaro zvavo zvekutsika panzvimbo.
Nzira yakarurama yakananga inogona kunge yakakurumidza kuchinjwa kuva kambo yekaseka kuburikidza nokubvisa chibatanidza uye kuisa zvakare mawambo nefoni dzakakodzera kutumira nekugamuchira.
