Patch Cord - kuyini? Yiziphi izinhlobo patch izintambo?

Patch izintambo (patch izintambo) abizwa ngokuthi kagesi noma fibre optic izintambo, okukuvumela ukuxhuma noma xhuma amadivayisi kagesi. I kabanzi kunazo idatha izinto etholwe design kanye ukudalwa amanethiwekhi wendawo endaweni. Ukuze compounds of ukushintshwa yokuxhuma workstation imishini inethiwekhi livame ukusetshenziswa patch intambo 5e, oluqanjwe indlela ezimbonini noma wezandla. Lezi zifundo zaphinde fibre optic patch izintambo.

Patch Cord - kuyini? Isebenza kanjani?

Ukuze uxhume disparate izingxenye inethiwekhi, udinga ukusebenzisa izintambo ekhethekile. Ngakho, ukuxhuma PC a router DSL noma ushintshele kudingeka alungiselele inethiwekhi ikhebula patch. Kuyini lokhu? Kuyinto ingxenye ethile kwakuvikela noma unshielded UTP ikhebula ubude 1.5 m, nhlangothi zombili zazo ziphephile esebenzisa ithuluzi crimping RJ-45 izixhumi. Ungasebenzisa lawa izintambo ukuxhuma cishe zonke izingxenye imvelo inethiwekhi. Okuhlukile amadivayisi asekela kuphela interface fibre. Ezinye ukushintshwa LAN Namanje wathola kumadivayisi ezisebenza phezu ikhebula coaxial. Manje cishe baye banyamalala.

Standard TIA-568A futhi TIA-568B

Kukhona amazinga ukuxhuma izintambo enjalo namanye amadivayisi: TIA-568A futhi TIA-568B. Pho-ke, isetshenziswa 5e patch intambo yokuxhuma kumadivayisi inethiwekhi? Emacophelo ichaze oda izintambo umuntu othile ngaphakathi isixhumi ngemibala. Iqiniso lokuthi ngaphakathi ejwayelekile UTP ikhebula i ukwahlukanisa ungqimba imicu kukhona babashayeli elisontiwe. Yilokho kuwo kanye isignali idluliselwa. ukwahlukanisa ungqimba esehlanganise umqhubi, kungase kudingeke omunye imibala eziyisishiyagalombili ejwayelekile:

• orange;
• white-orange;
• oluhlaza;
• emhlophe-oluhlaza;
• blue;
• okumhlophe nokuluhlaza;
• onsundu ngaphansi;
• omhlophe nonsundu.

Izinga TIA-568A oda inkomba iqala izintambo mhlophe futhi green, green. Ngo i samuntu, TIA-568B lokuqala ukuya izintambo orange. umehluko Okunye ngokulandelana eziphilayo kungabonwa esithombeni. Abanye onjiniyela inethiwekhi lapho yokuxhuma nezixhumi ezinqumela ukushintsha i-oda abaphilayo. Lokhu akunconyiwe. Kungcono ukulandela omunye izikimu ejwayelekile, ukugwema ukudideka esikhathini esizayo.

Lokho kungaba xhuma ikhebula le-patch?

Crimped nhlangothi zombili ikhebula lubaluleke umlawuli uhlelo. Kukhona amacebo amaningi ukuthi kungenziwa ixhunywe kwinethiwekhi usebenzisa ikhebuli patch. Kuyini kule divayisi? Loluhlu ngempela ebanzi. Lapha kuphela okukhethwa athandwa kakhulu yilezi:

• umugqa patch iphaneli a PC noma laptop;
• lekhompyutha imodemu DSL;
• Shintshela router noma shintshela kwenye;
• ikhompyutha emtapwei;
• DSL imodemu kudivayisi umzila noma inkinobho;
• zokungena bambonise inkinobho nge Poe ubuchwepheshe, noma ngaphandle kwalo.

Uma esetshenziswa lc lc patch intambo, ngokuvamile ehambisana idivayisi usuke kanye nomzila phakathi kwazo. Lolu hlobo ikhebula ibuye isetshenziswe yokuxhuma ukushintsha nezinye izinto inethiwekhi ukuba iphaneli patch.

Yiziphi ukushintshwa patch izintambo

Naphezu inkimbinkimbi kudivayisi, izintambo patch ukungezwani ezithile. Ngokwesibonelo, ingasho esigabeni 5, 5e, noma engu 6. sibalo uchaza lokho asetshenziswa zokwakha ikhebula, uhlobo RJ-45 nezixhumi usebenzisa ethile patch intambo UTP. Kusho ukuthini lokhu ku umkhuba? Abahlukahlukene UTP izintambo ukusekela ezahlukene ijubane ukudluliswa kwedatha. Ezinye zazo ukwazi ukunikeza abuye acale isignali yokudlulisela. CAT 6 ikhebula has ukuvikelwa ngokwengeziwe, kuvimbela ukushayisana e inethiwekhi ngenxa umsindo kagesi, nezinye izinto. It is eqinisekisiwe ukuze isetshenziswe Gigabit Ethernet amanethiwekhi. Isizathu esiyinhloko esenza isigaba 6-th akuzange wathola ukusatshalaliswa kwandile, yinani eliphezulu. Futhi eziningi izinkinga inethiwekhi kungase kahle ingaxazululwa esebenzisa ikhebula CAT 5 noma CAT 5e.

Gigabit ukwesekwa i-Ethernet, indaba izinga UTP amakhebuli

Kukhona owandile onganembile yabathengi, okuyinto bona kufuze babe ikhebula CAT 6, Gigabit ukuze ukwazi ukuthola isibonisi kunethiwekhi yakho. Lesi sitatimende sisebenza kuphela uma uthenge ezishibhile wire imvelaphi ezingabazisayo. okuhle izinga Isigaba 5e ikhebula, ekhiqizwa ngokucophelela imigomo lefanele, uzoba isignali Gigabit. ethile yayo kuphela ukuthi kwakungasebenzeki yakhelwe noma eqinisekisiwe salokhu. Ngakho-ke, asikho isiqinisekiso ukuthi ikhebuli CAT5 uyokusekela Gigabit Ethernet. Ngokuvamile, esinye sezici eyinhloko iyiphi inethiwekhi ikhompyutha zanamuhla is a intambo patch. Kusho ukuthini lokhu ku umkhuba? Iqiniso lokuthi izinga lo mkhiqizo izoncika kakhulu operation esitebeleni of inethiwekhi. Ngokwesibonelo, ukuvikelwa ababuthakathaka ngokumelene impambaniso yegetsi kungabangela inqwaba amaphutha nokwehlisa izinga idatha. Lokhu ngeke kuvunyelwe. Udinga ukuqapha ngokucophelela izinga UTP izintambo ukuthi asetshenziswa kwenethiwekhi yasendaweni.

umehluko temkhakha patch izintambo 5 no-6 imikhakha

Massively isetshenziswa ngokuyinhloko izintambo UTP Isigaba 5. Ziyakwazi ezishibhile, elula futhi enokwethenjelwa. Uma mikhiqizo zenziwa kahle, zingabantu, ngisho ngaphandle izinkinga izogcina isignali Gigabit. Kodwa ngezinye izikhathi ungathola nebala izintambo Isigaba 6 (cishe 3-5% of amacala). Yiziphi umehluko oyinhloko 5e patch ikhebula? Kuyini lokhu wire imilingo wasebenzisa yonke indawo? Lo mkhiqizo - esiku ikhebula ingxenye "pair ezisontekile", ekupheleni ngamunye ephethe RJ-45 Isixhumi. Ngalo, wire ufakwa okuhambisanayo isixhumi inkinobho noma inethiwekhi ikhompyutha umbadlana. Idatha idluliselwa imvamisa isukela kuze ku-100 MHz. patch okunjalo yezwi Kunconywa ukuba isetshenziswe ehlelekile cabling uhlelo (SCS). Ngakho ngokwesayensi ngokuthi amanethiwekhi kukhompyutha yakho yendawo. Twisted pair isigaba 5 futhi 5e ayinakho izingqimba yokuvikela, ngakho-ke kungenziwa kuphela emazingeni amakamelo avaliwe.

Yini izimfihlo namanje ofukamela isichibi intambo evamile? Ziyini lezi izici ezenza umkhiqizo ithuluzi enemisebenzi ngakho lokwakha amanethiwekhi computer? Yangaphandle ukwahlukanisa ungqimba kuvikela owodwa wire babashayeli zethusi, basonta ngababili nokuba ububanzi 0,52 mm. Umqhubi ngamunye embozwe polyethylene okuqinile. Kuvikela izintambo kusukela ukuphazamiseka ehlukahlukene ingress amanzi namachibi. UTP ikhebula kuyinto nezimo kakhulu, okukuvumela ukuthi usebenzise nemizila ezingalindelekile kunethiwekhi umzila.

Ezahlukahlukene cross-Patch Cord

Amandla amakhebuli we 'crossover' uhlobo olukhethekile pigtails, ezisetshenziswa kudivayisi RAS. engavamile wabo - Cross wesifunda uxhumano kuzintambo ngabanye ngqo isixhumi sekupheleni. Ngakho, uma isandla esisodwa imodeli esetshenziswa TIA-568A ke omunye isicelo TIA-568B wesifunda. Kungani kufanele ngisebenzisa cross-patch intambo? Yini eyenza? Ngenhla izintambo enjalo esetshenziswa ukuxhuma amakhompyutha komunye nomunye. Namuhla, lesi sinqumo ngokuyinhloko iphelelwe yisikhathi. Asikho isidingo ukuxhuma PC ngabanye ukuyisebenzisa ongakhetha Motocross ngaphandle kokushintsha imishini. inethiwekhi esibonakalayo amakhadi Modern baye bafunda ukuthi yimaphi ama izintambo asetshenziselwa ukudlulisa amasignali, futhi namanye kukhona reception. Ngakho-ke inkinga, okumele ukuxazulula le imishini inethiwekhi oyokwenziwa kahle ngokufanayo nanoma uhlobo ikhebula.
