Yintoni intambo yokukhanya yangaphandle?
Intambo yangaphandle yangaphandle luhlobo lwentambo yefiber optical esetyenziselwa ukuhanjiswa konxibelelwano. Ibonisa umaleko owongezelelweyo okhuselayo owaziwa ngokuba sisikrweqe okanye i-metal sheathing, enika ukhuseleko lomzimba kwimicu ye-optical, eyenza ibe yinto ehlala ixesha elide kwaye ikwazi ukusebenza kwiimeko ezinzima zokusingqongileyo.
I. Amacandelo Angundoqo
Iintambo zangaphandle zangaphandle zihlala zinemicu engenanto, ityhubhu ekhululekileyo, izinto ezithintela amanzi, izinto ezomelezayo, kunye neshethi yangaphandle. Ziza kwizakhiwo ezahlukeneyo ezinje ngoyilo lwetyhubhu esembindini, i-layer stranding, kunye nolwakhiwo lwamathambo.
Iifiber ezingenanto zibhekisela kwimicu ye-optical yasekuqaleni kunye nobubanzi obuyi-250 micrometers. Ngokuqhelekileyo babandakanya umaleko ongundoqo, umaleko wokugquma, kunye nomaleko wokugquma. Iindidi ezahlukeneyo zeentsinga ezingenanto zineesayizi ezahlukeneyo zomaleko ongundoqo. Ngokomzekelo, iifayili ze-OS2 ze-single-mode ziyi-9 micrometers, ngelixa i-multimode OM2 / OM3 / OM4 / OM5 iifayili ziyi-50 micrometers, kunye ne-multimode OM1 fibers yi-62.5 micrometers. Iintsinga ezingenanto zihlala zinekhowudi zombala zokwahlula phakathi kweentsinga ezininzi.
Iityhubhu ezixengayo zihlala zenziwe ngobunjineli obuphezulu bePBT yeplastiki kwaye zisetyenziselwa ukuhlalisa imicu engenanto. Babonelela ngokhuseleko kwaye bazaliswe ngejeli yokuthintela amanzi ukukhusela ukungena kwamanzi okungonakalisa imicu. Ijeli ikwasebenza njengesithinteli ukuthintela umonakalo wefiber kwiimpembelelo. Inkqubo yokwenziwa kweetyhubhu ezikhululekileyo ibalulekile ukuze kuqinisekiswe ubude obugqithileyo befiber.
Izinto zokuthintela amanzi zibandakanya igrisi yentambo yokuthintela amanzi, intambo yokuthintela amanzi, okanye umgubo wokuthintela amanzi. Ukwandisa ngakumbi isakhono sokuvala amanzi sisonke sentambo, eyona ndlela iphambili kukusebenzisa igrisi yokuthintela amanzi.
Izinto ezomelezayo ziza kwiintlobo zetsimbi kunye nezingezizo ezentsimbi. Ezentsimbi zihlala zenziwe ngeengcingo zentsimbi ezinephosphate, iiteyiphu zealuminiyam, okanye iiteyiphu zentsimbi. Izinto ezingezizo ezentsimbi zenziwe ngokuyintloko ngezinto ze-FRP. Nokuba yeyiphi na imathiriyeli esetyenzisiweyo, ezi zinto kufuneka zinike amandla omatshini ayimfuneko ukuhlangabezana neemfuno ezisemgangathweni, kubandakanya ukuchasana noxinzelelo, ukugoba, impembelelo kunye nokujija.
Iishethi zangaphandle kufuneka ziqwalasele imeko-bume yokusetyenziswa, kubandakanya ukuthintela amanzi, ukuxhathisa kwe-UV, kunye nokumelana nemozulu. Ngoko ke, izinto ezimnyama ze-PE zisetyenziswa ngokuqhelekileyo, njengoko iimpawu zayo ezibalaseleyo zomzimba kunye neekhemikhali ziqinisekisa ukufaneleka kofakelo lwangaphandle.
II. Iimpawu kunye nezicelo
Ukumelana noMlilo: Ngenxa yobukho beshethi yesinyithi, iintambo zangaphandle zamehlo zibonisa ukumelana nomlilo. Izinto zetsimbi ziyakwazi ukumelana nokushisa okuphezulu kwaye zihlukanise ngokufanelekileyo amalangabi, ukunciphisa impembelelo yomlilo kwiinkqubo zonxibelelwano.
Ukuhanjiswa komgama omde: Ngokukhuselwa komzimba okongeziweyo kunye nokuchasana nokuphazamiseka, iintambo zangaphandle zangaphandle zinokuxhasa ukuhanjiswa kwesignali yomgama omde. Oku kubenza babe luncedo kakhulu kwiimeko ezifuna ugqithiso olubanzi lwedatha.
Ukhuseleko oluPhezulu: Iintambo zangaphandle zangaphandle ziyakwazi ukumelana nokuhlaselwa ngokomzimba kunye nomonakalo wangaphandle. Ngenxa yoko, zisetyenziswa ngokubanzi kwiindawo ezineemfuno eziphezulu zokhuseleko lwenethiwekhi, njengeziseko zomkhosi kunye namaziko karhulumente, ukuqinisekisa ukhuseleko lwenethiwekhi kunye nokuthembeka.
III. Izinto eziluncedo ngaphezu kweeCables zeRegular Optical
Ukhuseleko loMzimba olomeleleyo: I-sheath yesinyithi yeentambo zangaphandle zangaphandle zikhusela ngokufanelekileyo i-fiber core kumonakalo wangaphandle. Ikhusela intambo ukuba ingacunyuki, yolulwe, okanye inqunyulwe, ibonelela ngokuzinzileyo nokuzinza okungcono.
Ukuxhathisa okuPhakamileyo koMbaneko: Isingxobo sesinyithi sikwasebenza njengokhuselo lwe-electromagnetic, luthintela ukuphazamiseka kwe-electromagnetic yangaphandle ekuchaphazeni ukuhanjiswa komqondiso kunye nokuphucula ukuxhathisa.
Ukuziqhelanisa noBume beNdawo Eburhabaxa: Iintambo zangaphandle zamehlo zinokusetyenziswa kwiindawo ezahlukeneyo ezirhabaxa, kubandakanywa amaqondo obushushu aphezulu naphantsi, ukufuma kunye nomhlwa. Oku kubenza bafaneleke ngakumbi kwiikheyibhili zangaphandle, unxibelelwano lwangaphantsi kwamanzi, ishishini, kunye nezicelo zasemkhosini.
Ukhuseleko olongezelelweyo lweMechanical: I-sheath yensimbi inokumelana noxinzelelo olubalulekileyo lomatshini kunye noxinzelelo, ukukhusela imicu kumandla angaphandle kunye nokunciphisa umngcipheko wokulimala kwentambo.
Kubalulekile ukuqaphela ukuba iintambo zangaphandle zangaphandle zinokuba neendleko eziphezulu kunye nobunzima bofakelo xa kuthelekiswa neentambo eziqhelekileyo. Ngenxa yobukho be-sheath yesinyithi, iintambo zangaphandle zininzi kwaye aziguquguquki kangako, okwenza ukhetho lohlobo lwekhebula olufanelekileyo lubaluleke kakhulu kwiimeko ezithile.
Ngokhuseleko lwalo oluqinileyo lomzimba, ukuchasana nokuphazamiseka, kunye nokulungelelaniswa kweendawo ezicela umngeni, iintambo zangaphandle zangaphandle ziye zaba yinto ekhethwayo kwizicelo ezininzi ezibalulekileyo, ezibonelela ngenkxaso ebalulekileyo yokuhanjiswa konxibelelwano oluthembekileyo.
