ZE120554NN Ethernet iModyuli yoQhagamshelwano lweJack 8P8C 1X4 RJ45 enoMbala
Iiplagi ze-RJ zohlulwe zibe ziindidi ezimbini: ezingakhuselekanga nezikhuselweyo.Iplagi ye-RJ ekhuselweyo igqunywe ngengubo yokukhusela, kwaye inkangeleko yayo yomzimba ayifani naleyo yeplagi engakhuselekanga.Kukwakho neplagi ye-RJ ekhuselweyo kwishishini ecetyelwe ngokukodwa indawo yefektri, eyabelwe kwaye isetyenziswe kunye nemodyuli yokukhusela.
Iiplagi ze-RJ zihlala zisebenzisa i-sheath yeplagi engagungqiyo, esetyenziselwa ukugcina iplagi yokuxhuma, ukuthintela ukutyibilika kunye nokuququzelela ukuplaga.Ukongeza, ineentlobo ngeentlobo zemibala onokukhetha kuyo, enokuthi inikwe umbala ofanayo nomfanekiso ofakiweyo wonxibelelwano oluchanekileyo.
Imodyuli yolwazi okanye iplagi yokudibanisa i-RJ kunye nokupheliswa kwesibini esijijekileyo sinezakhiwo ezibini, i-T568A okanye i-T568B, ezo ziyizakhiwo ezixhaswa yimigangatho yocingo jikelele ye-TIA / EIA-568-A kunye ne-TIA / EIA-568-B.Inombolo ye-RJ ye-crystal header ye-pin yokulandelelana kufuneka iphandwe ngolu hlobo lulandelayo: jikela umphambili weplagi ye-RJ (icala elinepini yobhedu) ukuya kuwe, isiphelo kunye nepini yobhedu phezulu, isiphelo sentambo yokudibanisa ezantsi, kunye ne-8. izikhonkwane zobhedu ukusuka ekhohlo ukuya ekunene.Iinaliti zibalwe ngokulandelelana ukusuka kwi-1 ukuya kwi-8.

Kwizixhobo ze-Ethernet, xa i-chip ye-PHY ixhunyiwe kwi-RJ, i-transformer yenethiwekhi idla ngokudibaniswa.Itephu esembindini yezinye iziguquli zenethiwekhi isekelwe.Abanye badityaniswe kunikezelo lwamandla, kwaye ixabiso lonikezelo lwamandla lingahluka, kubandakanywa i-3.3V, 2.5V, kunye ne-1.8V.Emva koko uqhagamshela njani impompo ephakathi (PHY ekupheleni) ye-transformer?
A. Kutheni ezinye iimpompo zaseziko ziqhagamshelwe kumandla?Ezinye ziphantsi?
Oku kumiselwa ikakhulu luhlobo lomqhubi wezibuko le-UTP letshiphu ye-PHY esetyenziswayo.Iintlobo zokuqhuba zihlulwe zibe: i-voltage drive kunye ne-current drive.Qhagamshela umbane xa uqhuba nge-voltage;qhagamshela i-capacitor emhlabeni xa uqhuba ngoku.Ke ngoko, indlela yoqhagamshelo yempompo yeziko inxulumene ngokusondeleyo nohlobo lwe-UTP ye-port drive ye-PHY chip.Kwangaxeshanye, nceda ujonge kwi-database kunye noyilo lwereferensi ye-chip.
Qaphela: Ukuba itephu ephakathi iqhagamshelwe ngokungalunganga, i-port yenethiwekhi iya kungazinzi kakhulu okanye ivalwe.
