Yintoni intambo ye-Optical yangaphandle?
Intambo ye-optical yangaphandle luhlobo lwentambo ye-optical fiber esetyenziselwa ukusasazwa konxibelelwano. Ine-layer eyongezelelweyo yokukhusela eyaziwa ngokuba yi-armor okanye i-metal sheathing, ebonelela ngokhuseleko olubonakalayo kwiintambo ze-optical, ezenza zihlale ixesha elide kwaye zikwazi ukusebenza kwiimeko ezinzima zendalo.
I. Izinto eziphambili
Iintambo ze-optical zangaphandle zihlala zinemicu engenanto, ityhubhu ekhululekileyo, izinto ezithintela amanzi, izinto eziqinisayo, kunye nesheath yangaphandle. Ziza ngezakhiwo ezahlukeneyo ezifana noyilo lwetyhubhu ephakathi, ukuxinana kweeleya, kunye nolwakhiwo lwamathambo.
Iifayibha ezingenanto zibhekisa kwiifayibha ze-optical zokuqala ezinobubanzi obuyi-250 micrometers. Zihlala ziquka umaleko oyintloko, umaleko wokugquma, kunye nomaleko wokugquma. Iintlobo ezahlukeneyo zeefayibha ezingenanto zinobukhulu obahlukeneyo beefayibha eziphambili. Umzekelo, iifayibha ze-OS2 zemo enye zihlala ziyi-9 micrometers, ngelixa iifayibha ze-OM2/OM3/OM4/OM5 ezininzi ziyi-50 micrometers, kwaye iifayibha ze-OM1 ezininzi ziyi-62.5 micrometers. Iifayibha ezingenanto zihlala zinemibala ukuze zahlulwe phakathi kweefayibha ezinee-core ezininzi.
Iityhubhu ezikhululekileyo zihlala zenziwe ngeplastiki yobunjineli enamandla aphezulu i-PBT kwaye zisetyenziselwa ukuhlalisa iintsinga ezingenanto. Zibonelela ngokhuseleko kwaye zizaliswe yijeli ethintela amanzi ukuthintela ukungena kwamanzi okunokonakalisa iintsinga. Ijeli ikwasebenza njengesithinteli ukuthintela umonakalo wefayibha kwiimpembelelo. Inkqubo yokwenziwa kweetyhubhu ezikhululekileyo ibalulekile ukuqinisekisa ubude obugqithisileyo befayibha.
Izinto zokuthintela amanzi ziquka igrisi yokuthintela amanzi ngentambo, intambo yokuthintela amanzi, okanye umgubo wokuthintela amanzi. Ukuphucula ngakumbi amandla okuthintela amanzi ngentambo, indlela eqhelekileyo kukusebenzisa igrisi yokuthintela amanzi.
Izinto eziqinisayo ziza ngohlobo lwesinyithi kunye nolwesinyithi. Ezesinyithi zihlala zenziwe ngeengcingo zentsimbi ezine-phosphate, iitheyiphu ze-aluminium, okanye iitheyiphu zentsimbi. Izinto ezingezizo zesinyithi zenziwe ikakhulu ngezinto ze-FRP. Nokuba zeziphi izinto ezisetyenzisiweyo, ezi zinto kufuneka zinike amandla oomatshini afunekayo ukuhlangabezana neemfuno ezisemgangathweni, kubandakanya ukumelana noxinzelelo, ukugoba, impembelelo, kunye nokujika.
Izikhonkwane zangaphandle kufuneka ziqwalasele indawo yokusetyenziswa, kubandakanya ukuthintela amanzi, ukumelana ne-UV, kunye nokumelana nemozulu. Ke ngoko, izinto ezimnyama ze-PE zisetyenziswa rhoqo, njengoko iipropati zazo zomzimba nezekhemikhali ziqinisekisa ukuba zifanelekile ukufakwa ngaphandle.
II. Iimpawu kunye nosetyenziso
Ukumelana Nomlilo: Ngenxa yokuba kukho isheya yesinyithi, iintambo ze-optical zangaphandle zibonisa ukumelana okuhle komlilo. Izinto zesinyithi zinokumelana nobushushu obuphezulu kwaye ziwahlukanise ngempumelelo amalangatye, zinciphisa impembelelo yomlilo kwiinkqubo zonxibelelwano.
Ukudluliselwa Komgama Omde: Ngokhuseleko oluphuculweyo lomzimba kunye nokumelana nokuphazamiseka, iintambo ze-optical zangaphandle zinokuxhasa ukudluliselwa kwesignali ye-optical kumgama omde. Oku kuzenza zibe luncedo kakhulu kwiimeko ezifuna ukudluliselwa kwedatha ebanzi.
Ukhuseleko Oluphezulu: Iintambo ze-optical zangaphandle zinokumelana nokuhlaselwa ngokwasemzimbeni kunye nomonakalo wangaphandle. Ngenxa yoko, zisetyenziswa kakhulu kwiindawo ezineemfuno eziphezulu zokhuseleko lwenethiwekhi, njengeziseko zomkhosi kunye namaziko karhulumente, ukuqinisekisa ukhuseleko kunye nokuthembeka kwenethiwekhi.
III. Iingenelo ngaphezu kweeCables zeOptical eziqhelekileyo
Ukhuseleko Oluqinileyo Lomzimba: I-sheath yesinyithi yeentambo ze-optical zangaphandle ikhusela ngempumelelo umongo wefayibha ekonakaleni kwangaphandle. Ithintela intambo ekutyumzweni, ekusolulweni, okanye ekunqunyulweni, nto leyo enika ukuqina nozinzo olungcono.
Ukumelana Nokuphazamiseka Okuphezulu: I-sheath yesinyithi ikwasebenza njengesikhuselo se-electromagnetic, ithintela ukuphazamiseka kwe-electromagnetic yangaphandle ekuchaphazeleni ukuhanjiswa kwesignali ye-optical kunye nokwandisa ukumelana nokuphazamiseka.
Ukuziqhelanisa neNdawo Ezinzima: Iintambo ze-optical zangaphandle zingasetyenziswa kwiindawo ezahlukeneyo ezinzima, kuquka amaqondo obushushu aphezulu naphantsi, ukufuma, kunye nokugqwala. Oku kuzenza zifaneleke ngakumbi kwiintambo zangaphandle, unxibelelwano lwangaphantsi kwamanzi, ushishino, kunye nokusetyenziswa kwezomkhosi.
Ukhuseleko olongezelelweyo lweMishini: Isiciko sesinyithi sinokumelana noxinzelelo olukhulu lwemishini kunye noxinzelelo, sikhusela imicu kwimikhosi yangaphandle kwaye sinciphise umngcipheko wokonakala kweentambo.
Kubalulekile ukuqaphela ukuba iintambo ze-optical zangaphandle zinokubangela iindleko eziphezulu kunye nobunzima bokufakelwa xa kuthelekiswa neentambo eziqhelekileyo. Ngenxa yokubakho kwe-metal sheath, iintambo zangaphandle zinkulu kakhulu kwaye aziguquguquki kangako, nto leyo eyenza ukukhetha uhlobo lwentambo olufanelekileyo kubaluleke kakhulu kwiimeko ezithile.
Ngenxa yokhuseleko lwayo oluqinileyo lomzimba, ukumelana nokuphazamiseka, kunye nokuziqhelanisa neemeko ezinzima, iintambo ze-optical zangaphandle ziye zaba lukhetho olukhethwayo kwiizicelo ezininzi ezibalulekileyo, zibonelela ngenkxaso ebalulekileyo yokusasazwa konxibelelwano okuthembekileyo.
