Kunzwisisa iyo RJ45 Connector: Iyo Musana weWired Networks!
Dive munyika yeEthernet networking ine gwara rakazara pane iyo RJ45 yekubatanidza, chimiro chayo, uye basa rayo rakakosha mukumhanyisa data data.
Ethernet uye RJ Standards:
Tekinoroji yeEthernet inogonesa kubatana kusina musono pakati pezvishandiso zvakawanda mukati metiweki, inotongwa nemapuroteni chaiwo anovimbisa kutaurirana kunoshanda. Akanyoreswa Jacks (RJ) akamisikidzwa emuviri maratidziro akagadzirirwa akasiyana network network. Pakati pavo, RJ45, RJ11, RJ48, uye RJ61 zvakapararira, imwe neimwe yakagadzirirwa kushandiswa kwakasiyana mukati meEthernet networking.
Iyo RJ45 Connector:
Iyo RJ45 yekubatanidza, inozivikanwa seyakanyoreswa Jack 45, yave iyo de facto chiyero chewaya network yekubatanidza. Pakutanga yakagadziridzwa nharembozha, yakabva yashanduka kuita ubiquitous muEthernet networking. Iyo "45" muRJ45 inomiririra yakasarudzika rondedzero mukati meakanyoreswa jack zvakatemwa.
Zvido zvehunyanzvi:
Inoratidzwa neyakakura fomu chinhu kana ichienzaniswa netambo dzenhare, iyo RJ45 yekubatanidza inogara yakafara bandwidth, kazhinji inosvika gumi Gbps. Uku kugona kwekumhanya-mhanya, pamwe chete neakawedzera kuchengetedza maficha, inoisa iyo RJ45 sechinhu chekubatanidza chekubatanidza makomputa emunhu kumaseva, marouters, uye mamwe network network.
Structural Composition:
Iyo RJ45 yekubatanidza inozvikudza 8-pini kumisikidzwa, inodaidzwa zviri pamutemo se8P8C, ichibvumira kubatanidzwa kwewaya sere. Inowanzo kubatanidzwa neShielded Twisted Pair (STP) kana Unshielded Twisted Pair (UTP) tambo, iyo RJ45 yekubatanidza inoonekera yepurasitiki casing inopa maonero akajeka emukati wiring.
Wiring Standards:
Paunenge uchinyatsotarisisa, munhu anogona kuona waya masere akasiyana mukati meRJ45 connector, inosiyaniswa nemavara akasimba uye ane mitsetse. Iyo RJ45 wiring yakakamurwa zvichienderana nekuita kwayo, ine zvikamu zvakaita seKatsi 5e, Katsi 6, uye Katsi 7, imwe neimwe ichipa akasiyana mazinga ekutapurirana kunaka uye bandwidth.
Ruvara Coding uye Zviyero:
Iko kukodha kwemavara kweRJ45 waya kwakamisikidzwa kuti zviite nyore kuzivikanwa uye kubatana. Zvirongwa zviviri zvekutanga zvemavara kodhi zviripo: T568A uye T568B. Iyo T568A yakajairwa inoisa waya dzakasvibira pamberi peorenji, nepo T568B ichidzosera iyi odha. T568A inova nechokwadi chekudzokera kumashure kuenderana nenhaka wiring masisitimu, nepo T568B yakagadzirirwa kudzikisira ruzha rwechiratidzo, ichivandudza kutendeseka kwedata.
Ndapota taura nesu kuti uwane rumwe ruzivo rwechigadzirwa uye Catalogs.
