Isikimu crimp pair ezisontekile RJ-45

Zikhona ongakhetha ahlukahlukene ukuxhuma lekhompyutha global Inthanethi, kodwa ezivame kakhulu namanje indlela usebenzisa ubuchwepheshe-Ethernet, okungukuthi, usebenzisa i-pair elisontiwe. Kulokhu, ikhebula exhunywe kwi-ikhadi inethiwekhi nge Isixhumi okhethekile - RJ-45. Okulandelayo sizobheka ukuthi kubukeka kanjani umdwebo crimp pair elisontiwe. Nokho, okokuqala kudingeka nikhulume nomklamo walo. pair Twisted limelela eyodwa noma ngaphezulu ngababili of babashayeli nesisontekile, baxhumane futhi embozwe emgodleni plastic. Esimweni sethu, labo ukuthi ukuxhuma kwi-Inthanethi usebenzisa i- ikhebuli inethiwekhi, okuhlanganisa ngazimbili ezine babashayeli.

Ngokulandelayo, kudingeka unqume ukuthi ngayiphi injongo lizosetshenziswa ngaphambi unamathisele isixhumi. Kukhona izikimu ezimbili crimp pair okusontekile:
- oqondile - ukuxhuma ikhompyutha ukuthi isikhungo inethiwekhi (a switch), ihabhu noma router;
- Cross (crossover) - yokuxhuma ama-computers amabili ngqo nomunye.

Uma kudingeka circuit oqondile crimp pair nesisontekile, izintambo both qeda of ikhebula ahlelwe ngendlela elandelayo:

Kuleli cala, uma wesifunda crimp pair ezisontekile - cross, indawo babashayeli kuzohluka:
Ngokuvamile, ama-computer inethiwekhi amakhadi yesimanje bayakwazi "ukuqonda" kanye wesifunda ngqo kuxhumana ngqo namatheminali PC ezimbili, kodwa sincoma kuphephe ukuxhuma nabo crossover.

Ngakho is crimped kanjani, pair ezisontekile? Lokhu kudinga ikhebula ngokwayo, yebhangqa RJ-45 nezixhumi (mhlawumbe eziningana) kanye crimping ekhethekile (noma Crimper), okuyinto has izindawo ezintathu ibhizinisi imisebenzi ethize. Esiseduzane isibambo ummese itholakala, lapho babashayeli kuthiwa ukusikiwa. Ezinye izinhlobo zawo babe futhi inkatho esikhethekile kokukhipha ukwahlukanisa elingaphandle ikhebula. Inombolo yomhlaba wonke yesikhungo itholakala Crimper esidlekeni, esebenza ngokuqondile ukuba crimp isixhumi. Futhi ekugcineni, engxenyeni engenhla kukhona endaweni ekhethekile esetshenziselwa bula ukwahlukanisa elingaphandle pair elisontiwe.

Ukuze uqale, usike ekupheleni ikhebula inethiwekhi, esakhelwe umsiki basihambise ngamasentimitha ambalwa kusukela ukwahlukanisa by ikhefu. Endabeni ka ukuntuleka kwayo kalula kwenziwe kusetshenziswa ummese ezivamile noma sikelo. Khona-ke alulaze, Unbraid kanye nokweseka pair of babashayeli. Ngemva kwalokho ziyabahlukanisa ngemibala, njengoba kuboniswa wesifunda oyifunayo crimping ngazimbili elisontiwe qondanisa. Uvalwe ngawakhamela wanquma imikhawulo nge Crimper ummese, kusale cishe 10 mm babashayeli unwound. Uzifake isixhumi, siqiniseke ukuthi i-tincetu waphumula semikhawulweni emikhombeni. Nalapha futhi, hlola indawo babashayeli ngemibala, beka RJ-45 we-earphone afanele.PARAGRAPH_END crimping impintshisi bese qinisa ekubambeleleni kwawo lize ukuchofozwa ikhebula ipulaki isamba.

Nokho, kungase kwenzeke ukuthi nginazo ngeke Crimper. Kulokhu, sebenzisa ukufakwa kokumqoka kuphela ezivamile mncane. Le ndlela isikhathi esiningi esiningi futhi kancane kahle, kodwa kungase kube usizo ezimweni eziphuthumayo. Ngokuvamile, inqubo okufana nalokho okuchazwe ngenhla. Umahluko owokuthi ukuthi ukuze ungawuzwa clove RJ-45 oxhumana nabo, udinga ukubeka ingcindezi phezu kwabo, ekupheleni ukufakwa kokumqoka kuphela, zisabalaliswe, kwesithi egcwele amazinyo atihambi todvwa. Kufanele push kanzima, kodwa ngesikhathi esifanayo ngokucophelela.

Ukuze ukuhlola crimped pair ezisontekile has a idivayisi ekhethekile - LAN-lomhloli. Nokho, ngezinye izikhathi ongakwenza ngaphandle kwalo - kodokotela esincane noma abangenaso nhlobo zokusebenza kuyoba sobala ukuze endaweni ethile kwakukhona iphutha.

Ngakho, kumelwe sikuqonde lokho pair nesisontekile, crimping scheme, kanye namathuluzi ngawo ungenza ikhebula inethiwekhi. Njengoba ubona, inqubo ulula futhi Akudingi ulwazi olukhethekile namakhono - ukunakekelwa kuphela.
