Maitiro Akaita Makombiro Akaoma Akabatana Anoshanda
Kuberekerwa Jack 45 (RJ45) inoratidziro rwechimiro chemuviri chetambo cables. RJ45 nhengo dzakawanda dzinowanzoonekwa neEthernet cables uye mitambo.
Nhare dzemazuva ano Ethernet dzinoshandisa duku plastiki plugs panopera imwe neimwe iyo inowanikwa muRJ45 jacks yeEthernet mafoni. Izwi rokuti "ipulagi" rinoreva kukanda kana kuti "murume" kuguma kwekubatanidza apo izwi rokuti "jack" rinoreva chikamu kana kuti "mukadzi" kuguma.
RJ45, RJ45s, uye 8P8C
RJ45 mabhugi anoita mapepa masere ayo masimbi ematare echetheni inoshandisa magetsi. Puregi imwe neimwe ine nzvimbo zvisere dzakasara dzinenge 1 mm pane imwe iyo mahwindo ari kuiswa achishandiswa pakushandiswa kwekamberi kashandisi. 8P8C, shorthand yeEight Position, Eight Contact).
Ethernet cables uye 8P8C connectors vanofanira kunyoreswa muRJ45 wiring pattern kuti iite zvakanaka. Nenzira, 8P8C inogona kushandiswa nedzimwe mhando dzekubatana kunze kweEthernet; iyo inoshandiswawo ne -RS-232 serial cables, somuenzaniso. Zvisinei, nokuti RJ45 ndiyo inonyanya kushandiswa kwe 8P8C, vashandi vemabhizimisi vanogara vachishandisa mazwi maviri nenzira imwe neimwe.
Nharaunda yekuisa- modem modems inoshandiswa kusiyana kweRJ45 inonzi RJ45s, iyo inongotaura chete mazita maviri mu 8P2C sarudzo pane masere. Kufanana kwepamwechete kweRJ45 neRJ45s kwakaita kuti zvive nyore kune ziso risina kudzidza kuti vataure vaviri vari voga.
Wiring Pinouts yeRJ45 Connectors
Mhando mbiri RJ45 pinouts inotsanangura urongwa hwomunhu mumwe nomumwe masere anodiwa paanobatanidza kuwirirana kune tambo: T568A uye T568B mitemo. Zvose izvi zvinotevera gungano rekuputira mahwindo mumwe mune imwe yevashanu mavara-mavara, mavara, maruva, machena, kana machena-nemamwe mavara uye akabatanidzwa zvakasimba.
Kutevera izvi kokorodzano kunokosha kana uchigadzira cables kuti uone kuti magetsi anoenderana nemimwe midziyo. Nokuda kwezvikonzero zvezvekare, T568B yave yakave yakakurumbira. Tafura iri pasi apa inopfupikisa iyi coding.

Mamwe mhando dzezvibatanidza zvakafanana zvakafanana neRJ45, uye dzinogona nyore nyore kuvhiringidzwa. RJ11 nhengo dzinoshandiswa nematare efoni, somuenzaniso, shandisa nhanhatu nheyo dzisungo pane nzvimbo gumi nesere dzisungo, zvichiita kuti dzive shoma kudarika RJ45 connectors.
Matambudziko Ane RJ45
Kuti uite ushamwari hwakasimba pakati pemapulagi uye nhamba yekutengesa, mamwe RJ45 plugs anoshandisa chidimbu chiduku, chinonzi bendable chepurasitiki chinonzi tab. Iyo tab inoita chisimbiso chakasimba pakati pekambo uye ganda pakunyoresa, zvinoda munhu kuti ashandise mamwe ekudzvinyirira pasi pane tab kuti abvumira kusunungura. Izvi zvinobatsira kudzivirira kambani kubva pakangoerekana isununguka. Zvinosuruvarisa, mabheti aya anongoruka nyore nyore kana akadzokera shure, izvo zvinoitika apo chibatanidza chinoputika pane imwe kambani, zvipfeko, kana chimwe chinhu chiri pedyo.
