Pinout yakakoswa peya

Modern nzira Internet kuwana kubatana kupa zvakawanda kuita: kushandisa coaxial waya, internet optic uye vaviri wakarukwa. Ngationei kugara pamusoro zvechadenga zononoka wire uye sei pinout chakagadzirwa yakakoswa peya, chii chinodiwa uye chii mitemo zvinofanira kutevedzerwa.

Zvakamonyana peya anonzi tambo vari vakamonyanisa uye yakafukidzwa kuputira. A zvakamonyana waya ringave riine maviri kana mana dzakamonyana yegwara waya, akaisa mune dielectric mumuhara. Waya vari yakasiyana voltage mashoko chiratidzo yawapihwa navo. Mhando anoverengeka yakakoswa-vaviri vangazivikanwa. Vane unshielded, foil ane zvokunze chidzitiro, foil ane peya nechitarisiko sefa, akadzivirira uye zvaitawo kudzivirirwa. Zvakamonyana peya ane chinetso. Kana huchishanda pane njodzi kuvhura mashoko pachishandiswa waya. Tiza zvakafanira kuti vadzivise eavesdropping. Ukuwo kudzivirirwa netambo dziri zvinodhura chaizvo uye saka kashoma kushandiswa.

The netambo, izvo zvinoshandiswa kusarurama peya, akakamurwa muzvikamu akawanda. Chokutanga runhare wire kuparadzira mashoko. By chikamu wire 2 anogona nekufambisa mashoko ari kakawanda boka kusvika imwe megahertz, Category 3 - gumi nezvitanhatu megahertz, chikamu 4 - kuti makumi maviri megahertz. Last kwakanyorwa kashoma kushandiswa, nekuti anenge asina rakasiyana waya 3 mhando.

Zvikuru akakwana panguva ichaongororwa wechishanu muchikwata wire, yakagadzirirwa nokupfuuridzirwa mashoko ari frequencies anosvika zana megahertz. Zvakamonyana peya chikamu 5 haasi asingasviki maviri nemanomwe majana por mita pakureba. Kazhinji, pane zvakawanda zvidimbu, makumi maviri nemashanu nomwe. The waya zvakakodzera unobatanidza makombiyuta Indaneti uye pakusika omunzvimbo network. Kune netambo 6 ne7 Mapato, izvo azvaitwa dzaona kuti 200 uye 600 megahertz. Category 6 waya inoshandiswa kubatanidza kuti Ethernet network.

Kana unobatanidza veko rezvebonde makombiyuta zviviri vane matambudziko. Kuti akunde navo uye vanyatsoshandisa Zvakanyanya Kunaka Panguva Yepamuviri kubatana, zvinoda Network makadhi makombiyuta uye vaviri yakakoswa, kureva muchikwata wechishanu, uyewo connectors vari RJ-45.

Sezvo netambo rinoumbwa yakakoswa mbiri, anonetsa racherwa rusvingo nzira yokubudisa, zvinotoda crimp ravo, iro rinoitwa maererano nemitemo uye kushandiswa dzinokosha nematurusi haana mapiro date hutachiwana. Kana waya ane conductors masere, akabata pinout vakamonyanisa vaviri Ethernet uye Gigabit Ethernet mitemo. Nokuti kuti netambo dziri muchikwata 5 uye 6 inoratidza tsime racho torsion uye vachikotama, vari vakabudirira kushandiswa mukugadzira pamusoro nama tambo anobatana arikunze nehoro.

Kugara embodiments maviri, ayo anoshandiswa unobatanidza makombiyuta pomumbure kana kubatanidza munhu PC kune zvakarukwa Hardware (tambo). Uyezve, yose emo rezvebonde anogona kushandisa shanduro imwe chete, iyo ichaitwa musi yakakoswa-vaviri pinout. The waya unofanira kugadzirira kupinza kupinda connector. Zvinokosha kucherechedza kuti zvose RJ-45 connector anofanira crimped zvakafanana. Kune mhando mbiri crimping, iro rinoshandiswa yakakoswa vaviri. Wokutanga (mberi kuitira) rine mirayiridzo "workstation Hub". Wechipiri - muchinjikwa, muchinjikwa Linkova.

Kubatanidza zvakananga pomumbure kadhi iri makombiyuta maviri, unofanira sanganisa kuti waya kuitira kuti vaviri (somuenzaniso, orenji uye rwegirini) kuchinjwa. Saka pinout akasungwa yakakoswa peya wire, somugumisiro iyo mumwe connectors kuti crimped wokutanga musimboti, uye wechipiri - yechipiri. The waya Ipapo achanzi Crossover. Anonziwo nulhabnym.

Nokudaro, kushandisa yakakoswa maviri anonzi kuva kudekara chokugadza vakaderera mutengo. Nezano conductors vane chikuru chiratidzo attenuation uye Inonyanya kubatanidza Internet, kuvandudza acho akashandiswa pinout vakamonyanisa peya wire kuti anobvumira kuti ajairane yeimwe aine kombiyuta uye peripherals.
