Sei crimp munhu kusarurama peya Ethernet 100 Mb

Nechekare pamwe veMubatanidzwa vokutanga makombiyuta akauya kudiwa nyore uye nokutsanya nzira digitaalinen pakukurukurirana pakati pavo. Perforated machira, rinobva matepi uye disks (pakutanga kuchinja uye ipapo vanachandagwinyira), Manyiminya vezvenhau kunyange zvishomanana rwakapedza dambudziko, asi avo kushandiswa ane drawback - zvakafanira neimwe nzira kuti tiite mutakuri achaendesa Data kuti kubaya kombiyuta, saka " kurerukirwa "zvaikosha ndokunge.

Hazvishamisi kuti eighties paiva nomukana tama mashoko pakati digitaalinen mano kuburikidza sangano nomumbure kubatana pakati pavo (Ethernet). In nerimwe kombiyuta anovamba chinokosha adapteri (picnic), iro rinobatanidza coaxial waya zvakabatana. Izvi akabvumira wokushandura mashoko zvakananga, sezvakatenderanwa Ethernet mureza 10BASE2 (dzimwe zvipenyu zviri zvishoma yaizivikanwa uye isingawanikwi zvikuru). Zvisinei, mureza waida kuti impedance yacho waya rakanga 50 ohms, zvichiita kuti zviome kubvisa zvichibvira kukuvara.

With veMubatanidzwa yakawanda yemazuva ano, kutsanya kuti Ethernet, kutsigira kuchinjwa ukurumidze kusvika 100 megabits, coaxial waya akatsiviwa zvakamonyororwa peya. Kuwedzera kuderedza mari yokumbozorora chero cores vaigona kungosimuka kumonyanisa uye adzikunure chidimbu. Chii chinonzi yakakoswa peya? Izvi majoko akawanda pamusoro kwadzo conductors akaruka mbiri uye dzakaunganidza mune rimwe nevamwe. Muitisi inogona akararama seboka, uye rava wakaisvonaka bvudzi mhangura. The nzira yokutanga - hunde unowanzoshandiswa kuvaka masvingo pakuparadzirwa nehoro. Step plexus peya imwe neimwe yakasiyana, izvo zvinoderedza crosstalk. Waya dziri kusiyaniswa sedare kuputira, saka "bhaza" hakusi zvakakodzera.

Dzimwe nguva mubvunzo unomuka, chii chigamba netambo. Ndiyo unobatanidza waya pamwe connectors pamicheto yehombodo. Kazhinji, kureba iri shoma 5 m, kunyange muhofisi mureza TSB-75 ndicho okurambidzwa chinobviswa. Kana uchida kubatanidza makombiyuta maviri mumwe, kuti chigamba wire inogona kutengwa chero kuchitoro zvigadzirwa kombiyuta.

Panzira, sezvinoita mutemo, kwakadai waya "vakamonyanisa peya". uye mutengi haafaniri kufunga kuti crimp yakakoswa peya, nokuti connectors vakatobatana zvakabatana mune imwe nzira (kazhinji PC-kuti-PC, muchinjikwa-batanidza kana "Crossover"). Cherechedza kuti vakawanda ano mano vapiwa ticherechedze mhando kubatana uye kuchinja nayo. Zvisinei, dzimwe nguva unofanira iwe kunzwisisa sei crimp yakakoswa peya. Somuenzaniso, muna vanongozvifunga vanoungana Lan.

Muchiitiko ichi zvakafanira kuverenga akakodzera forum uye nokurondedzerwa. Panzira, kuti dzvinya yakakoswa vaviri, hapana kunzwisisa - zvishoma kutarisirwa uye kururama.

Unogona kutenga chaiyo crimping pingisi, mutengo iwayo nyore. Kunyange zvazvo, pamwe wakakodzera unyanzvi, zvose zvaungaita kunyange nezvipikiri.

Saka, sei kuti crimp yakakoswa peya? Kunoda waya pacharo (nokuti kusarurama peya chikamu 5 pa 100 Mbit vakaomerwa kure - vanenge 130 m) uye mbiri RJ-45 connector. Chekai netambo pamupendero, tsitsi uye akagura kukuvara. Kubvisa chokunze paiva kuputira. Kureba mugove ichi kunobva mhando connector: yokupedzisira vanofanira kugadzira chifukidziro chikamu uye kwete vanonyatsoteerera vamwe conductors. Vakaroorana kukanganisika uye swatanudza (vanofanira kutaura pana 1 cm). Maererano zano (ona pazasi) dzinoisa waya kupinda connector. Pamwe mites batanidza waya kwavari.

Pane nzira mbiri kuti crimp - T568A (kambani Siemon), uye T568B (AT & T). Zvinowanzoshandiswa chechipiri mhando. Yokutanga anonongedzera vari chinopfuudzwa pamusoro yegwara "chena-rwegirini" uye "chena-orenji", uye Orange uye mitema waya. Wechipiri peya "chena-orenji" uye "mutema-chena" uye achachena mitema.

Kubatanidza mano siyana (nomusimboti-PC) rinoshandiswa zvakafanana nzira iyo yeimwe kubva kumativi. Kana uchida kubatanidza makombiyuta maviri kana maviri nomusimboti, kuti pazuva rimwe ruoko waya akaberekwa nokuda T568A, uye kuno rumwe - on T568V. Visual wiring chati inogona nyore kuwanikwa musi kuMudzidzisi zvinhu padandemutande.

Council nokuti "simbe": kuumba nyore richikurukura hrs maviri unogona kutenga wakagadzirira akagadzirwa nama netambo uye waya "peya kusarurama" kuti achida urefu. Kucheka chigamba tambo pakati, kuchenesa kumagumo conductors payo uye kunyanya waya monyorora (solder) chinoumba maererano ruvara Coding. Insulated. Izvi mhinduro inoshanda zvakanaka madaro anosvika 140 m.
