Pinout pair ezisontekile

izindlela zesimanje Inthanethi ukufinyelela ukuxhumana ukunikela ongakhetha eziningana: usebenzisa ikhebula coaxial, fibre optic futhi pair elisontiwe. Ake abahlala izici ikhebula Kuvunguza nendlela pinout wenziwe pair nesisontekile, lokho okudingekayo futhi yini imithetho kumele ilandelwe.

pair Twisted ubizwa ngokuthi izintambo ukuthi okokusonteka futhi wambozwa ukwahlukanisa. Intambo ezisontekile elakhiwa ngazimbili ezimbili noma ezine ezisontekile izintambo, ibekwe endaweni emgodleni Kwe-dielectric Heating. I izintambo kukhona at ezahlukene isignali Imininingwane voltage enikeziwe ngazo. izinhlobo eziningana ezisontekile-pair kungathiwa. Ziyakwazi unshielded, ucwecwe nge isikrini zangaphandle, ucwecwe nge pair zesikrini zangaphandle, avikelwe futhi kwakuvikela evikelwe. pair Twisted has eyodwa kusimo. Lapho ukusebenza kwawo kukhona ingozi ukucabhela Imininingwane wadluliselwa ikhebula. Escape kubalulekile ukuze ugweme ngilalele ekusithekeni. Ngakolunye uhlangothi izintambo kwakuvikela abasakwazi eqolo ngakho-ke kuyaqabukela asetshenziswa.

I izintambo, ezisetshenziswa pair ezisontekile, izigaba eziningana. Esokuqala ikhebula ngocingo ngokudlulisa inkulumo. Ngu isigaba ikhebula 2 bangadlulisela lwazi yokuhlela ibhendi yokuvama elilodwa megahertz, Isigaba 3 - nesithupha megahertz, isigaba 4 - ukuze amabili megahertz. Kugcine it is kuyaqabukela asetshenziswa, ngoba cishe akuhlukile ikhebula 3 izigaba.

I ephelele kakhulu okwamanje kubhekwa owesihlanu isigaba ikhebula, eyenzelwe yokudlulisa ulwazi ku amaza afika ku eziyikhulu megahertz. Twisted pair isigaba 5 akuyona esingaphansi ematfuba amabili nesikhombisa imitha ubude ngamunye. Ngokuvamile, kukhona izingcezu eziningana, ngazimbili amabili nanhlanu. Ikhebula kufanelekile yokuxhuma amakhompyutha ku-inthanethi futhi ukudalwa amanethiwekhi wendawo. Kukhona izintambo 6 no-7 izigaba, okuyinto ngokulandelana ibalwa for 200 kanye 600 megahertz. Isigaba 6 ikhebula isetshenziselwa ukuxhuma-Ethernet amanethiwekhi.

Uma uxhuma kunethiwekhi lendawo amakhompyutha okungenani ezimbili ukuba babe nezinkinga. Ukuze unqobe kubo futhi wenze uxhumano elilungile kakhulu, zidinga inethiwekhi amakhadi zekhompyutha pair nesisontekile, ebhekisela esigabeni yesihlanu, kanye nezixhumi kukhona RJ-45.

Njengoba izintambo ehlanganisa ngazimbili nesisontekile, kunzima ukuba uthathe esidayisa odongeni, kuthatha crimp zabo, okuyinto eyenziwa ngokuvumelana nezindinganiso kanye nokusetshenziswa kwamathuluzi ekhethekile alithintwa izinga ukudluliswa kwedatha. Uma ikhebula has babashayeli eziyisishiyagalombili, aphethwe pinout basonta pair-Ethernet futhi Gigabit amazinga-Ethernet. Ngenxa yokuthi izintambo kukhona isigaba 5 no 6 ukubonisa kahle ngokwaso torsion nokugotshiswa, bajwayele ngempumelelo yokukhiqiza of patch izintambo ukuthi ukuxhumana Izitolo azungeze.

Hlala embodiments ezimbili, ezisetshenziswa for yokuxhuma amakhompyutha kunethiwekhi noma ukuxhuma PC ihadiwe inethiwekhi (izintambo). Ngaphezu kwalokho, kuyo yonke inethiwekhi yendawo angasebenzisa version eyodwa kuphela, okuyinto izobanjelwa ku ezisontekile-pair pinout. Ikhebula kumele uzilungiselele ukuze ishuthekwe isixhumi. Kuyaphawuleka ukuthi kokubili RJ-45 Isixhumi kufanele crimped ngokulinganayo. Zimbili izinhlobo crimping, okuyinto lisetshenziswa umbhangqwana elisontiwe. I (oda phambili) wokuqala isiqondiso "workstation Hub". Esesibili - esiphambanweni, cross-Linkova.

Ukuze uxhume ngqo ikhadi inethiwekhi ye-computers amabili, udinga ukuba alulaze ikhebula ukuze umbhangqwana (isibonelo, orange futhi oluhlaza) emuva. Kanjalo pinout Kunenkolelo ezisontekile pair ikhebula, ngenxa okuyinto omunye nezixhumi ukuba crimped ukuze samuntu kuqala, futhi eyesibili - in the yesibili. Ikhebula izobe ngokuthi i crossover. Futhi kubizwa nulhabnym.

Ngakho, Buhle ngazimbili ezisontekile ubhekwa kalula ukufakwa futhi eziphansi. babashayeli sasisendaweni abe mkhulu isignali attenuation futhi ezivamile ukuxhuma kwi-Inthanethi, ukuthuthukisa ikhwalithi yenqubo esetshenziswa pinout basonta pair ikhebula evumela ukuzivumelanisa compounds nge-computer bese okuphathelene nomngcele.
