Ngaphakathi kwentambo yi-copper core wire;ngaphakathi kwintambo yokukhanya yifiber yeglasi.Intambo idla ngokuba yintambo efana nentambo eyenziwe ngokujija amaqela amaninzi okanye aliqela eingcingo (iqela ngalinye ubuncinane ezimbini).Intambo yamehlo ngumgca wonxibelelwano oqulunqwe inani elithile lemicu ye-optical ngendlela ethile kwaye igqunywe nge-sheath, kwaye ezinye zigqunywe nge-sheath yangaphandle ukuqonda ukuhanjiswa kwesignali ye-optical.
Xa ifowuni iguqula isignali ye-acoustic ibe ngumqondiso wombane kwaye emva koko idlulisele ekutshintsheni ngomgca, umtshintshi uhambisa uphawu lombane ngokuthe ngqo kwenye ifowuni ngomgca wokuphendula.Umgca wothumelo ngexesha le ncoko yintambo.
Xa ifowuni iguqula isignali ye-acoustic ibe yisignali yombane kwaye idlulisele kwi-switch ngokusebenzisa umgca, utshintshi ludlulisela uphawu lombane kwisixhobo sokuguqula i-photoelectric (ukuguqula umqondiso wombane ube ngumqondiso we-optical) kwaye uyithumele kwesinye isixhobo sokuguqula i-photoelectric. ngelayini (iguqula isignali yokubona).Umqondiso uguqulwa ube ngumqondiso wombane), kwaye emva koko kwisixhobo sokutshintsha, ukuya kwenye ifowuni ukuphendula.Umgca phakathi kwezixhobo ezimbini zokuguqula i-photoelectric yintambo ye-optical cable.
Intambo ikakhulu icopper core wire.Iidayamitha zocingo ezingundoqo zahlulwe zibe yi-0.32mm, 0.4mm kunye ne-0.5mm.Ubukhulu bedayamitha, kokukhona bomelela amandla onxibelelwano;kwaye ngokwenani leentambo ezingundoqo, kukho: izibini ezi-5, izibini ezili-10, izibini ezingama-20, izibini ezingama-50, izibini ezili-100, 200 Ewe, linda.Iintambo ze-Optical zihlulwe kuphela ngenani leentambo eziphambili, inani leentambo eziphambili: 4, 6, 8, 12 pairs njalo njalo.
Intambo: Inkulu ngokobukhulu, ubunzima, kwaye iyalambatha kubuchule bonxibelelwano, ngoko inokusetyenziswa kuphela kunxibelelwano olufutshane.Intambo ye-Optical: Ineenzuzo zobukhulu obuncinci, ubunzima, ixabiso eliphantsi, umthamo omkhulu wonxibelelwano, kunye nokukwazi ukunxibelelana olomeleleyo.Ngenxa yezinto ezininzi, okwangoku isetyenziselwa kuphela umgama omde kunye ne-point-to-point (oko kukuthi, amagumbi amabini okutshintsha) ukuhanjiswa konxibelelwano.
Ngokwenyani, umahluko phakathi kweentambo kunye neentambo ze-optical zibonakaliswa ikakhulu kwimiba emithathu.
Okokuqala: Kukho umahluko kwizinto eziphathekayo.Iintambo zisebenzisa izinto zetsimbi (uninzi lwethu ubhedu, i-aluminium) njengabancedisi;iintambo zamehlo zisebenzisa iintsinga zeglasi njengabancedisi.
Okwesibini: Kukho umahluko kwisignali yothumelo.Intambo ihambisa imiqondiso yombane.Iintambo ze-Optical zihambisa imiqondiso ye-optical.
Okwesithathu: Kukho iiyantlukwano kububanzi besicelo.Iintambo ngoku zisetyenziselwa ukuhanjiswa kwamandla kunye nokuhanjiswa kwedatha yesiphelo esisezantsi (njengefowuni).Iintambo ze-Optical zisetyenziselwa ukuhanjiswa kwedatha.
Kwizicelo eziphathekayo, kuyaziwa ukuba iintambo ze-optical zinamandla amakhulu okuhambisa kuneentambo zobhedu.Icandelo le-relay linomgama omde, ubungakanani obuncinci, ubunzima bokukhanya, kwaye akukho ukuphazamiseka kwe-electromagnetic.Ngoku sele iphuhlise imigca emikhulu yomgama omde, i-intra-city relays, offshore and trans- Umqolo wonxibelelwano lwe-submarine yolwandle, kunye neentambo zothumelo lwentambo zothungelwano lwengingqi, uthungelwano lwabucala, njl. uthungelwano losasazo lwelophu yomsebenzisi esixekweni, ukubonelela ngeentambo zothumelo zefiber-to-ekhaya kunye ne-broadband edibeneyo yenkonzo yothungelwano lwedijithali.
