ZE120554NN Efaneti Cholumikizira Module Jack 8P8C 1X4 RJ45 Yokhala Ndi Mtundu
Mapulagi a RJ amagawidwa m'mitundu iwiri: osatetezedwa komanso otetezedwa.Pulagi ya RJ yotetezedwa imakutidwa ndi zokutira zotchingira, ndipo mawonekedwe ake sasiyana ndi pulagi yosatetezedwa.Palinso pulagi ya RJ yotetezedwa ndi mafakitale yomwe idakonzedweratu kuti ikhale malo a fakitale, yomwe imaperekedwa ndikugwiritsidwa ntchito ndi gawo lotchinga.
Mapulagi a RJ nthawi zambiri amagwiritsa ntchito sheath yosasunthika, yomwe imagwiritsidwa ntchito posungira pulagi yolumikizira, kuteteza kutsetsereka ndikuthandizira plugging.Kuphatikiza apo, ili ndi mitundu yosiyanasiyana yosankha, yomwe ingaperekedwe ndi mtundu wofanana ndi chithunzi chophatikizidwa kuti mulumikizane bwino.
Gawo lachidziwitso kapena pulagi yolumikizira ya RJ ndi kutha kwa awiri opotoka ali ndi zigawo ziwiri, T568A kapena T568B, zomwe ndizomwe zimathandizidwa ndi miyezo yolumikizira ya TIA/EIA-568-A ndi TIA/EIA-568-B.Nambala yotsatizana ya RJ crystal header pini iyenera kufufuzidwa motere: tembenuzirani kutsogolo kwa pulagi ya RJ (mbali ndi pini yamkuwa) kwa inu, mapeto ndi pini yamkuwa mmwamba, mapeto a chingwe cholumikizira pansi, ndi 8. zikhomo zamkuwa kuchokera kumanzere kupita kumanja.Singano amawerengedwa motsatizana kuyambira 1 mpaka 8.

Mu zida za Efaneti, pomwe chipangizo cha PHY chilumikizidwa ndi RJ, chosinthira maukonde nthawi zambiri chimawonjezeredwa.Kupopera kwapakati kwa ma transfoma ena amtaneti kumakhazikika.Zina zimalumikizidwa ndi magetsi, ndipo mphamvu yamagetsi imatha kukhala yosiyana, kuphatikiza 3.3V, 2.5V, ndi 1.8V.Ndiye momwe mungalumikizire kampopi wapakati (PHY end) wa thiransifoma?
A. Chifukwa chiyani matepi ena apakati amalumikizidwa ndi mphamvu?Ena amakhazikika?
Izi zimatsimikiziridwa makamaka ndi mtundu wa oyendetsa doko la UTP wa chipangizo cha PHY chomwe chimagwiritsidwa ntchito.Mitundu yamagalimoto imagawidwa kukhala: ma voltage drive ndi ma drive apano.Lumikizani magetsi poyendetsa ndi voteji;gwirizanitsani capacitor pansi pamene mukuyendetsa ndi panopa.Chifukwa chake, njira yolumikizira pompopi yapakati imagwirizana kwambiri ndi mtundu wa UTP port drive wa PHY chip.Nthawi yomweyo, chonde onani tsatanetsatane ndi kapangidwe ka chip.
Zindikirani: Ngati kampopi wapakati alumikizidwa molakwika, doko la netiweki lidzakhala losakhazikika kapena lotsekedwa.
