Pulogalamu ya network yomwe imakonda kugwiritsidwa ntchito kwa basi, sizigwirizana ndi ma netiweki ozungulira kapena owoneka bwino. Node onse ndi gawo lolumikizidwa ndi basi imodzi ndi chisankho chabwino, m'chithunzi pamwambapa, kupembedza kwatsopano kwa A8-05B kukuwonetsedwa. N ma node olumikizidwa mu ma netwonera. Pathamanga kwambiri ndi mizere yayitali, kusungunuka kofunikira kumafunikira mbali zonse ziwiri za mzere kuti muchotse ziwonetsero. Gwiritsani ntchito 100 ω ω zotsutsana ndi malekezero onse (amangofunika ngati waya wa waya> 2km). Network iyenera kupangidwa ngati mzere umodzi wokhala ndi madontho angapo, osati ngati nyenyezi. Ngakhale kutalika kwathunthu kapena kumafupikira mu kasinthidwe nyenyezi, kukhazikika kokwanira sikothekanso kuwonongeka kwakukulu kumatha kuwonongeka kwambiri. Mu chithunzi 1 chomwe chinawonetsa pambuyo pake, B, D, F ndi kulumikizana kolondola ndi a, C, e ndi cholakwika.
Chithunzi 1
Mukamagwiritsa ntchito waya wa shield
Waya wofunikira
Dongosolo limagwiritsa ntchito Cab-5E UTP ndi chingwe cholimba.
Kodi mungasankhe bwanji chingwe choyenerera 5E?
Kutsutsa kwa waya uliwonse kuyenera ≤35ω pomwe kutalika ndi pafupifupi305m (kutalika kwa FCL).
Malo osungirako khomo logwiritsa ntchito RVVE4 * 0,5, kutseka ogwiritsa ntchito RVV2 * 0.5.
CHENJEZO:
Chithunzithunzi cha khomo kapena chithunzithunzi chokwanira pazenera lowoneka bwino m'chipinda chowoneka bwino chipinda chija chosiyana kwambiri ndi magetsi oyendetsa magetsi, m'malo oyenerera m'basi yomanga kuti muthetse vutoli. Mphamvu ya Vidiyo Yapamwamba Kwambiri Yochokera ku malo owoneka bwino kwambiri sinathe kupitirira 30 metres.

Bwanji osagwiritsa ntchito RJ-45 kuti mulinduke?
Chifukwa muyezo wa RJ-45 umapangidwa kuti ukhale mu chitseko chokha chongogwiritsa ntchito kokha, chitsimikiziro chonyowa komanso chopanda tanthauzo kapena chopanda maxidi. Ngati mutu wa RJ-45 wasweka, pali akatswiri atagwira zida zaluso zofunira kuti akonze cholakwika, izi zimabweretsa ndalama zapamwamba.
Scotchlok ndi zomwe tikufuna. Zaka zopitilira 45 zapitazo, 3m adayambitsa cholumikizira choyambirira cha mafakitale - cholumikizira scotchlok ur. Masiku ano, ndikukula kwa kuchuluka kwa maukonde apamwamba komanso okwera kwambiri, zolumikizira kwathunthu za 3m ndi zida zasinthidwanso. Chonde pitani pa www.3m.com kuti mudziwe zambiri za Scotchlok.
