Ethernet waya: tsananguro, chinangwa, marudzi zvinogadzirwa

Nokuti kuisa kombiyuta network vanoshandisa Ethernet chinokosha waya (Lan-waya). Kune mhando dzakawanda inokosha waya pair yakakoswa, coaxial, uye internet optic. Chokutanga mhando ichaongororwa kuva yakachipa pashiri uye iri nyore, saka rinoshandiswa vanopfuura 90 muzana zvose network yemo.

Mhando yakakoswa peya

This Ethernet wire It ndicho uye vakakurumbira. Inoitwa conductors sere mhangura kuti tose zvakanyatsobatana. The kuputira zvinhu inoshandiswa tefa PVC. Kune mhando dzakawanda yakakoswa peya, zvakasiyana kubva mumwe mhando wokudzivirira kana kushaya kwayo. Unodzivirira basa anogona kuita aruminiyamu foil yakapombera tambo, kana mhangura chirukwa peya imwe. Uyezve, pane yaisanganisa siyana kudzivirirwa. Ethernet Kudzivirirwa waya zvakawanda nemishonga zvokunze chipingaidzo, asi ukuwo, ine ukoshi hukuru. Kunewo mamwe marudzi anoverengeka yakakoswa-vaviri, izvo zvinoratidzwa chiratidzo "CA", iro anosarudza muchikwata yacho waya. Kune marudzi manomwe parameter ichi. The kumusoro muchikwata nhamba, chikuru inogona ari waya, kureva anoshandisa zvakawanda conductors. Saka, muchikwata che yakakoswa peya (wokupedzisira musi) rechinomwe unokubvumira nekufambisa mashoko pa aimhanya 40 Gbit / s. Kupa nokukurumidza zvakadaro pasina kukanganiswa chiratidzo, peya nomumwe conductors ari waya vanofanira kuva sevanhu impedance 100 ohms.

Ethernet coaxial waya

mhando iyi waya rinoumbwa nemunhu uye chinovhara ane nevakawanda akabatana kuti kutenderera. The waya unotora nemunhu, imwe insulator, PVC mumuhara, mhangura kana aruminiyamu ruka. Nhasi, ichi mhando waya kushandiswa nemunhu nokuda kanyanga. Local network, akarongeka ari coaxial netambo, anenge hapana. The inonyanya waya pamwe mamirire impedance 50 ohms - kombiyuta Network - uye 77 ohms - wokushandura neterevhizheni chiratidzo. The kunonyanyisa date yedzimudzangara vanokwanisa ndiyo 10 Mbit / s. Uyezve, zvisingaiti, sezvo ari chaizvo kunzwisisa zvokugadzirisa tagovera dzoga, vakazochinja kunounza zvinokosha nezvinhu.

Manyiminya faibha

Izvi Ethernet netambo vanoonekwa ne yakaderera attenuation, kunyange kana kuparadzira mashoko pamusoro madaro marefu, havana pasi kukanganiswa. Uyezve, mashoko Manyiminya faibha ane kumhanya rokushandura. Nokuti kugadzira pasi review, kuti waya kunoda unyanzvi hwakasiyana zvishandiso uye midziyo, uye kudiwa kubatanidza spectral michina. Izvi mhando haawanzopiwi kushandiswa pakuvaka network iri mufurati kana hofisi, nekuti, mukuwedzera wakaoma, ine panzvimbo yakakwirira mutengo.

Ethernet-waya pinout

Standard mana vaviri akamonyana peya kuvaka network vemo crimped connector RJ-45 mhando. kubatana zano rine zvinotevera hurongwa: chena-nyoro, mutema, muchena, orenji, zvitema, chena, zvitema, orenji, mashava uye chena uye mashava waya. Crimping Zvirongwa akasiyana zvichienderana chinangwa unobatanidza mitsetse, ruzivo uye mitemo ruzivo chinja. Dzimwe nguva vanoshandisa mberi uye kuzvishandura (muchinjikwa) crimp connector.
