Ngokuthuthuka kwesayensi nobuchwepheshe, ikhebula lenethiwekhi kanye ne-fiber optical sekuyizithwali ezimbili ezibaluleke kakhulu ekudlulisweni kwesignali yenethiwekhi.Ekudluliselweni kwesignali, i-fiber optical inezinzuzo eziningi, njengebanga elide lokudlulisela, isignali ezinzile, ukuncishiswa okuncane, isivinini esikhulu, njll., ehlangabezana nanoma yiziphi izidingo ezidingekayo zenethiwekhi.Ibulala ngokuphelele ikhebula lenethiwekhi njalo ngomzuzu, ngakho-ke uyini umehluko phakathi kwentambo ye-optical fibre patch nentambo yenethiwekhi?
Izincazelo ezahlukene
I-patch cord empeleni iyintambo yokuxhumana yensimbi exhuma amaphuzu amabili esidingo sebhodi lesifunda (PCB).Ngenxa yemiklamo ehlukene yomkhiqizo, intambo yesichibi isebenzisa izinto ezihlukahlukene nobukhulu.
Intambo yenethiwekhi ibalulekile ukuze uxhume i-LAN.Izintambo zenethiwekhi ezivamile kumanethiwekhi endawo ikakhulukazi ahlanganisa ipheya esontekile, intambo ye-coaxial kanye nentambo yokubona.I-twisted pair iwumugqa wokudlulisa idatha ohlanganiswe ngamapheya amaningi ezintambo.Isici sawo ukuthi ishibhile, ngakho-ke sisetshenziswa kabanzi, njengezintambo zethu zocingo ezivamile.Isetshenziselwa ukuxhuma ne-RJ45 modular plug.
Imiphumela ehlukene
I-patch cord isetshenziswa kakhulu ekudluliselweni kwamandla kagesi ngamandla afanayo kanye ne-short-circuiting kanye nokuxhuma izintambo ezimbili.Kulabo abanezidingo zamandla kagesi ezinembile, ukwehla kwamandla kagesi okukhiqizwa yintambo yesichibi yensimbi encane nakho kuzoba nomthelela omkhulu ekusebenzeni komkhiqizo.Ikhebula lenethiwekhi lisetshenziselwa ukudluliswa kwedatha nokuxhuma kunethiwekhi yendawo yangakini kanye nokudlulisa ulwazi kunethiwekhi.
Ukusetshenziswa kwezinto ezahlukene
Izinto ezisetshenziselwa intambo yesichibi yikhebula lethusi, elenziwe ngentambo ye-patch ejwayelekile kanye ne-hardware yokuxhuma.I-patch cord inama-copper cores asukela kuma-cores amabili kuya kwayisishiyagalombili, kanti i-hardware yokuxhuma ingamapulagi amamojula angu-6-bit noma angu-8-bit, noma Anamakhanda ocingo olulodwa noma ngaphezulu angenalutho.Enye intambo yokuchibiyela inepulaki yemojuli kwelinye icala kanye nembobo yemojula engu-8-bit ngakolunye uhlangothi, noma ifakwe amapulaki ezintambo angu-100P, ama-MIC, noma izikhala zemojuli.
Kukhona ikakhulukazi ikhebula elisontekile elisontekile, ikhebula eliqinile nentambo yokubona.I-twisted pair iwumugqa wokudlulisa idatha ohlanganiswe ngamapheya amaningi ezintambo.Isici sawo ukuthi ishibhile, ngakho-ke sisetshenziswa kabanzi, njengezintambo zethu zocingo ezivamile.Isetshenziselwa ukuxhuma nekhanda lekristalu le-RJ45.Ine-STP ne-UTP.I-UTP isetshenziswa kakhulu.
