Ingaphakathi lekhebula yintambo yethusi ewumgogodla;ingaphakathi lekhebula le-optical fiber ingilazi.Ikhebula ngokuvamile liyikhebula elifana nentambo elakhiwe ngokusonta amaqembu amaningana noma amaningana ezintambo (iqembu ngalinye okungenani amabili).Ikhebula le-optical liwumugqa wokuxhumana owakhiwe inombolo ethile yamafiber optical ngendlela ethile futhi embozwe ngesheath, kanti amanye abuye ambozwe ngesheath yangaphandle ukuze abone ukudluliswa kwesignali ye-optical.
Lapho ifoni iguqula isignali ye-acoustic ibe isignali kagesi bese iyidlulisela ekushintsha ngolayini, iswishi idlulisela isignali kagesi kwenye ifoni ngolayini ukuze iphendule.Ulayini wokudlulisela phakathi nale ngxoxo intambo.
Lapho ifoni iguqula isignali ye-acoustic ibe isignali kagesi futhi iyidlulisela emshinini ngolayini, iswishi idlulisela isignali kagesi kudivayisi yokuguqula ugesi wesithombe (iguqula isignali kagesi ibe isignali yokubona) bese iyidlulisela kwenye idivayisi yokuguqula ugesi ngomugqa (iguqula isignali yokubona).Isignali iguqulwa ibe isignali kagesi), bese iye empahleni yokushintsha, iye kwenye ifoni ukuze iphendule.Ulayini ophakathi kwamadivayisi amabili okuguqula i-photoelectric yikhebuli yokubona.
Ikhebula ngokuyinhloko iyi-copper core wire.I-core wire diameters ihlukaniswe ngo-0.32mm, 0.4mm no-0.5mm.Ubukhulu be-diameter, amandla okuxhumana aqina;futhi ngokwenani lezintambo eziwumgogodla, kukhona: amapheya ayi-5, amapheya ayi-10, amapheya angama-20, amapheya angama-50, amapheya ayi-100, angama-200 Yebo, linda.Izintambo ezibonakalayo zihlukaniswa kuphela ngenani lezintambo eziyinhloko, inani lezintambo eziyinhloko: 4, 6, 8, 12 pair nokunye.
Ikhebula: Inkulu ngosayizi, isisindo, futhi impofu ngamakhono okuxhumana, ngakho ingasetshenziswa kuphela ekuxhumaneni okufushane.Intambo yokubona: Inezinzuzo zosayizi omncane, isisindo, izindleko eziphansi, umthamo omkhulu wokuxhumana, namandla okuxhumana aqinile.Ngenxa yezici eziningi, okwamanje isetshenziselwa kuphela ukuhambisa ibanga elide kanye nokukhomba-ephuzwini (okungukuthi, amagumbi amabili okushintshanisa) ukudlulisa ukuxhumana.
Empeleni, umehluko phakathi kwezintambo nezintambo ezibonakalayo ubonakala ikakhulukazi ezicini ezintathu.
Okokuqala: Kunomehluko ezintweni ezibonakalayo.Amakhebuli asebenzisa izinto zensimbi (ikakhulukazi ithusi, i-aluminium) njengamakhondu;izintambo ezibonakalayo zisebenzisa imicu yengilazi njengama-conductor.
Okwesibili: Kunomehluko kusiginali yokudlulisela.Ikhebula lidlulisa amasignali kagesi.Izintambo zokukhanya zidlulisa amasignali okubona.
Okwesithathu: Kunomehluko kububanzi bohlelo lokusebenza.Amakhebuli manje asetshenziswa kakhulu ekudluliseni amandla kanye nokudluliswa kolwazi lwedatha olusezingeni eliphansi (njengocingo).Izintambo ezibonakalayo zisetshenziswa kakhulu ekudluliseni idatha.
Ekusetshenzisweni okungokoqobo, kungaziwa ukuthi izintambo ezibonakalayo zinamandla amakhulu okudlulisela kunezintambo zethusi.Ingxenye ye-relay inebanga elide, usayizi omncane, isisindo esilula, futhi akukho ukuphazamiseka kwe-electromagnetic.Manje isisungule imigqa yeziqu ezide, amalayidi angaphakathi kwedolobha, i-offshore kanye ne-trans- Umgogodla wezokuxhumana ezingaphansi kolwandle, kanye nemigqa yokudlulisa enezintambo yamanethiwekhi wendawo, amanethiwekhi angasese, njll., isiqalile ukuthuthukela emkhakheni. yamanethiwekhi okusabalalisa iluphu yomsebenzisi edolobheni, ehlinzeka ngezintambo zokudlulisa ze-fiber-to-ekhaya kanye namanethiwekhi edijithali e-broadband adidiyelwe.
