Momwe mungadziwire chingwe cha coaxial chomwe chili pa intaneti
Zamkatimu
Mukawerenga nkhaniyi, mudzatha kudziwa kusiyana pakati pa chingwe cha intaneti cha coaxial ndi zingwe zonse za coaxial m'nyumba mwanu.
Zingwe za coaxial zimagwiritsidwa ntchito m'malo osiyanasiyana monga mawu, makanema ndi intaneti. Chifukwa chake, kuzindikira chingwe cha coaxial chomwe chimagwiritsidwa ntchito pa intaneti ndizovuta. Ndiye, ndi chingwe chiti cha coaxial chomwe ndiyenera kulumikiza ku rauta yanga? Umu ndi momwe mungadziwire chingwe cha coaxial chomwe chili pa intaneti.
Nthawi zambiri, mutha kugwiritsa ntchito ma RG pamawaya kuti muzindikire chingwe cha intaneti cha coax. Zingwe za RG-8, RG-6 ndi RG-58 zimagwiritsidwa ntchito potumiza deta pa intaneti. Mutha kupeza zolemba izi kumapeto kwa cholumikizira chingwe cha coaxial kapena pakati.
Werengani nkhaniyi pansipa kuti mumve zambiri.
Njira yabwino yodziwira zingwe za coaxial pa intaneti
Pakadali pano, zingwe za coaxial zimagwiritsidwa ntchito polumikizira wailesi, wailesi yakanema komanso intaneti.
Panthawiyi, mungakhale mukuyang'ana mulu wa zingwe za coax ndipo simukudziwa kuti ndi iti. Pazadzidzidzi, simudzadziwa chingwe cholumikizira ku rauta yanu. Ichi ndichifukwa chake kuzindikira chingwe cha intaneti cha coaxial ndikofunikira kwambiri.
Poganizira izi, nayi njira yosavuta komanso yachangu yopezera zingwe za coaxial pa intaneti pakati pa ena onse.
Kuzindikiritsa chingwe cha coaxial ndi RG rating
Mavoti a RG ndi njira yabwino yodziwira zingwe za intaneti za coaxial. Koma kodi RG ratings?
RG imayimira Radio Guide. Posankha zingwe za coaxial, opanga amagwiritsa ntchito dzina la RG ili ndi manambala monga RG-6, RG-59, RG-11, ndi zina zotero. Dzina la RG ili likuyimira mitundu yosiyanasiyana ya zingwe za coaxial.
Zingwe za coaxial zomwe zimagwiritsidwa ntchito polumikizira intaneti zimalembedwa kuti RG-6, RG-8, ndi RG-58. Mitundu itatu iyi ndi yofala kwambiri.
Chifukwa chake, zomwe muyenera kuchita ndikupeza chizindikiro cha RG pa chingwe, ndipo chizindikirocho chiyenera kukhala kumapeto kwa cholumikizira cha chingwe, kapena pakati.
Komabe, ngati mukugwiritsa ntchito zingwe zakale, simungathe kuwona zolembera molondola. Nthawi zina zizindikiro zimatha kuphimbidwa ndi fumbi. Ngati ndi choncho, yeretsani waya ndikuyang'ana mlingo wa RG.
Nazi zina zomwe muyenera kudziwa za zingwe za RG zomwe zatchulidwa pamwambapa.
Onani chithunzi pamwambapa. Uku ndikuyerekeza pakati pa zingwe za RG-58 ndi RG-6. Chingwe chakumanzere ndi RG-58 ndipo kumanja ndi RG-6. Monga mukuwonera, chingwe cha RG-6 ndi chokulirapo kuposa chingwe cha RG-58. Ndi kuyerekeza uku, mutha kumvetsetsa kukula kwa chingwe cha RG-8.
RG-58
Chingwe cha RG-58 chimagwiritsidwa ntchito makamaka pamapulogalamu 50 ohm. Imayesa 20 AWG.
RG-8
RG-8 ndi chingwe chokhuthala cha 50 ohm. Ndi 12 AWG.
RG-6
Chingwe cha RG-6 chimatha kugwira ntchito za 75 ohm. Ndi 18 AWG.
Kodi chingwe chabwino kwambiri cha intaneti ndi chiyani?
Ndikuganiza kuti zingwe zonse zitatuzi ndizosankha zabwino pa intaneti. Koma ndikadayenera kusankha, ndikadasankha RG-6.
Chingwe cha RG-6 chili ndi gawo lokulirapo komanso kutsekereza kokulirapo. Momwemonso, bandwidth yake yayikulu ndiyabwino kugwiritsa ntchito intaneti, TV ya satellite, ndi chingwe TV.
Tsopano mukudziwa momwe mungasankhire chingwe cha coaxial pa intaneti. Koma kodi mukudziwa momwe mungadziwire kuti ndi coaxial iti yomwe ili ndi chizindikiro chabwino kwambiri?
Kuti muchite izi, mufunika coaxial cable tester. Ndipo nayi momwe mungagwiritsire ntchito kuti mupeze zotsatira zabwino kwambiri za coax.
- Yatsani choyesa chingwe cha coaxial.
- Bweretsani woyesa kumalo enaake.
- Ngati chizindikiro cha LED ndi chofiira, chizindikirocho ndi chofooka.
- Ngati chizindikiro cha LED ndi chobiriwira, chizindikirocho ndi champhamvu.
Chidule mwamsanga: M'malo molumikizana ndi chithandizo nthawi iliyonse mukataya chizindikiro, ndibwino kukhala ndi choyesa chingwe cha coax.
Zomwe muyenera kudziwa za zingwe za coaxial pa intaneti
kamangidwe
Zingwe zapaintaneti za coaxial zili ndi mawonekedwe ozungulira komanso kondakitala wamkuwa. Komabe, kutchinjiriza kumatenga makulidwe ambiri a chingwe (m'malo mwa conductor yamkuwa). Chifukwa cha kusungunula kwakukulu, woyendetsa mkuwa akhoza kutumiza deta popanda kuwonongeka kwa kunja kapena kusokoneza.
Pulasitiki dielectric insulator imateteza woyendetsa wamkuwa. Pamwamba pa insulator ya dielectric ya pulasitiki pali chophimba chachitsulo. Pomaliza, chotchinga chakunja chapulasitiki chimateteza kutsekereza kwamkati ndi kokondakita.
Kachitidwe kachitidwe
Kutumiza kwa data pa kondakitala yamkuwa ndi magwiridwe antchito a zingwe za coaxial pa intaneti. Chifukwa cha zigawo zowonjezera, simudzamva kutayika kwa chizindikiro. Mwa kuyankhula kwina, imachepetsa kusokoneza kwa electromagnetic.
Kuthamanga
Zingwe zapaintanetizi zimatha kusamutsa deta pa liwiro loyambira 10 Mbps mpaka 100 Mbps (megabits pa sekondi).
Mafunso ofunsidwa kawirikawiri
Kodi chingwe cha intaneti cha coaxial chingapite pati?
Zingwe za coaxial zimadziwika kuti zimakhala nthawi yayitali kuposa zingwe zina zambiri. Amatha kuthamanga mpaka mamita 500. Mtengo uwu ndi 1640.4 mapazi. Komabe, mtengo uwu ukhoza kusiyana malinga ndi mtundu wa chingwe ndi mphamvu ya chizindikiro.
Kodi kutalika kwa chingwe cha coaxial kumakhudza chizindikiro cha intaneti?
Inde, kutalika kwa chingwe kumakhudza chizindikiro cha intaneti. Mwachitsanzo, mudzawona kutayika kwa ma siginecha ndi utali wautali wa chingwe. Chizindikiro ichi chitayika chifukwa cha kukana.
Pamene kutalika kwa kondakitala kumawonjezeka, kukana kwa conductor kumawonjezeka. Kutalika kwakutali kumatanthauza kukana kwakukulu, zomwe zikutanthauza kutayika kwa chizindikiro cha intaneti.
Monga lamulo, mtunda wochokera ku chingwe cha coaxial Internet ukuwonjezeka, kutayika kwa zizindikiro zotsatirazi kungayembekezeredwe.
- 20% kutayika kwa chizindikiro pamamita 50
- 33% kutayika kwa chizindikiro pamamita 100
Kodi ndingagwiritse ntchito chingwe cha coaxial pa intaneti?
Ayi, simungagwiritse ntchito chingwe cha coaxial pa intaneti. Zina mwa izo zidapangidwa kuti zizilumikizana ndi wailesi kapena wailesi yakanema, pomwe zina zidapangidwa kuti zizitumiza mauthenga pa intaneti. Chifukwa chake, muyenera kugula chingwe cha coaxial chomwe chimathandizira kutumiza kwa data pa intaneti. Zingwe za RG-6, RG-8 ndi RG-58 ndi zingwe zodziwika bwino za intaneti za coaxial pamsika. (1)
Kodi kukana kwa ma ohms a zingwe za coaxial pa intaneti ndi chiyani?
Mukayika zingwe zapaintaneti za coaxial kutengera kulephera kwawo, mitundu iwiri ya zingwe imasiyanitsidwa; 50 ohm ndi 75 ohm. Zingwe za 50 ohm zimagwiritsidwa ntchito kwambiri polumikizirana opanda zingwe komanso kutumiza ma data. Ndipo zingwe za 75 ohm zimagwiritsidwa ntchito pazizindikiro zamakanema. (2)
Onani zina mwazolemba zathu pansipa.
- Momwe mungayang'anire chizindikiro cha chingwe cha coaxial ndi multimeter
- Komwe mungapeze waya wandiweyani wamkuwa wa zidutswa
- Waya wa 18 gauge ndi wokhuthala bwanji
