Pinout zopotoka awiri

njira zamakono mgwirizano Internet mwayi zopereka njira zingapo: ntchito coaxial chingwe, CHIKWANGWANI chamawonedwe ndi awiri zopotoka. Tiyeni akukhala pa makhalidwe a chingwe mwauzimu ndi mmene pinout unapangidwa awiri zopotoka, zofunikira ndi malamulo ayenera kutsatiridwa.

Zopotoka awiri amatchedwa mawaya amene anapotoza wokutidwa ndi kutchinjiriza. A chingwe zopotoka Mwina amapanga awiri kapena anayi awiriawiri wopota mawaya, anaikidwa m'chimake dielectric. Mawaya ali osiyana voteji mudziwe chizindikiro umaperekedwa ndi iwo. mitundu yambiri ya zopotoka-awiri tingaone. Iwo unshielded, zojambulazo ndi chophimba zakunja zojambulazo ndi awiri zowonetsera kunja, kuteteza ndi lotetezeka kutetezedwa. Zopotoka awiri ali sangathe wina. Pamene ntchito zake pali chiopsezo kudutsana wa mudziwe kudzera mwa chingwe. Kuthawa m'pofunika kuti kupewa mobisa zimene ankaphunzira. Komano zingwe lotetezeka ndi okwera mtengo kwambiri choncho kawirikawiri ntchito.

The zingwe, amene ntchito ziwirizi zopotoka, m'magulu angapo. Choyamba ndi chingwe telefoni zimayambitsa kulankhula. Ndi gulu chingwe 2 angathe kupatsira zambiri mu gulu pafupipafupi kuti megahertz wina, Category 3 - kuti megahertz sikisitini, gulu 4 - makumi awiri megahertz. Otsiriza sikawirikawiri ntchito, chifukwa pafupifupi munthu wosiyana chingwe 3 siyana.

Wangwiro kwambiri pa nthawi imatengedwa wachisanu gulu chingwe, anaikira kufala kwa mudziwe mu mafurikwense wa megahertz mpaka zana. Zopotoka awiri gulu 5 si zosakwana ankasinthana twente-seveni pa mita m'litali. Kawirikawiri, pali zidutswa zingapo, awiriawiri twente-faifi. chingwe ndi oyenera kulumikiza kompyuta kwa Internet ndi chilengedwe Intaneti wamba. Pali zingwe 6 ndi magulu 7, amene ankalemekeza masamu chifukwa 200 ndi 600 megahertz. Category 6 chingwe ntchito kulumikiza Intaneti Efaneti.

Pamene kulumikiza kwa maukonde m'dera makompyuta osachepera awiri ndi mavuto. Pofuna kuthana nazo ndiponso kupanga kugwirizana kwambiri mulingo woyenera, amafuna makadi zopezera makompyuta ndi awiri zopotoka, kunena gulu chachisanu, komanso zolumikizira ndi RJ-45.

Popeza zingwe ongokhala awiriawiri zopotoka, ndi ovuta kusema khoma kubwereketsa, pamafunika crimp awo, yomwe ikuchitika malinga ndi malangizo ntchito zipangizo zapadera kuti si bwanji khalidwe la kufalitsa deta. Ngati chingwe ali ochititsa eyiti unachitika pinout anapotoza awiri Efaneti ndi Gigabit mfundo Efaneti. Chifukwa chakuti zingwe ndi gulu 5 ndi 6 kusonyeza bwino yokha mwa torsion ndi kupinda, iwo ali bwinobwino ntchito kupanga zingwe chigamba kuti kugwirizana ndi malo ogulitsira pa periphery.

Amakhala embodiments awiri, amene ntchito polumikiza makompyuta kuti maukonde kapena kulumikiza ndi PC kwa hardware maukonde (zingwe). Komanso lonse m'dera maukonde akhoza kugwiritsa ntchito Baibulo limodzi lokha, lomwe udzachitike pa zopotoka-awiri pinout. chingwe ayenera kukonzekera mayikidwe mu cholumikizira lapansi. Dziwani kuti onse RJ 45 cholumikizira ayenera crimped mofanana. Pali mitundu iwiri ya crimping, omwe umagwiritsidwa ntchito pa awiri zopotoka. Woyamba (kutsogolo kuti) ali ndi chitsogozo "kaphatikizidwe kamakompyuta Pankakhala". The chachiwiri - mtanda mtanda Linkova.

Kulumikiza mwachindunji khadi zopezera makompyuta awiri, muyenera kuchepetsa chingwe kuti awiri (mwachitsanzo, lalanje ndi obiriwira) adzagonjetsa. Choncho pinout umachitika zopotoka awiri chingwe, chifukwa cha amene zolumikizira kuti crimped kuti chimake choyamba, ndipo chachiwiri - wachiwiri. chingwe The ndiye kutchedwa kusinthanitsidwa. Amatchedwanso nulhabnym.

Choncho, mwayi wa awiriawiri zopotoka imatengedwa kukhala omasuka unsembe ndi mtengo wotsika. Shackleton ochititsa ndi wamkulu chizindikiro attenuation ndipo ambiri kugwirizana Internet, kusintha khalidwe la ndondomeko ntchito pinout anapotoza awiri chingwe chimene chimathandiza kuti azolowere mankhwala ndi kompyuta ndi peripherals.
