Njengoko Apha ngezantsi kukho intshayelelo emfutshane umzobo wocingo we-ADSS fibre optic cable
1. Ifayibha engenanto
Okuncinci ukuguquguquka kwedayimitha yangaphandle ye-ADSS fiber optical, kungcono.Ukuguquguquka kwedayamitha yefiber optical kunokubangela ilahleko yamandla ebuyela umva kunye nelahleko yefayibha yokudityaniswa kwefiber optical.Ukuguquguquka kwedayamitha yangaphandle ye-ADSS ifayibha ebonakalayo ibangela ukuguquguquka kwedayamitha engundoqo kunye nedayamitha yemo yentsimi, ekhokelela ekwandeni kwelahleko yokusasazeka kwefiber kunye nelahleko yesplice.
Kungcono ukulawula ukuguquguquka kwedayamitha yangaphandle yefiber optical ngaphakathi ± 1μm.Ukwandisa isantya sokudweba ucingo, ukunciphisa ngokufanelekileyo ubushushu bomzobo wocingo, kwaye unciphise ixesha lokuhlala le-preform kwisithando somlilo esiphezulu.Ukunciphisa ukusasazwa kokufuma kwi-cladding kwindawo entsha kunenzuzo ekunciphiseni ukuthotywa okongeziweyo komzobo wefayibha.Ukwandisa isantya umzobo kunye nokwandisa umzobo umzobo kunokunciphisa ukuguquguquka kwedayamitha yangaphandle, kwaye kwakhona kunceda ukunciphisa isizukulwana E 'iziphene.Kwakhona kunenzuzo ukunyusa amandla e-fiber.Nangona kunjalo, umzobo wocingo olunesantya esiphezulu udinga amandla aphezulu okufudumeza iziko, oqheleke ngakumbi kwibala lobushushu elingalinganiyo.Kuya kuba nempembelelo enkulu kwi-warpage yefiber (i-warpage ibhekisela kwi-radius ye-curvature ehambelana nokugoba kwefiber engenanto ngaphandle koxinzelelo lwangaphandle).Isizathu esona sizathu sokuchaphazela i-warpage kukuba i-fiber ifudumala ngokungafaniyo kwintsimi yeqondo lokushisa, okubangelwa ukucutha okungafaniyo kwefiber kwicala lentamo, okubangelwa ukuhla kwe-warpage yefiber.I-warpage ye-fiber optical sesinye sezibonakaliso abasebenzisi be-ADSS optical cable baxhalabele kakhulu.Ngokukodwa kwi-fiber optical, ukuba i-warpage ye-fiber optical incinci kakhulu, iya kuzisa iziphumo ezibi kwikhonkco.
Ngenxa yokuba i-ADSS ifayibha yokubona ifayibha yomlilo enesantya esiphezulu ineemfuno ezisisiseko zilandelayo:
A. Yila ulwabiwo olufanelekileyo lobushushu kunye noyilo lwendlela yegesi ukuvelisa ubume bentamo obufanelekileyo.
B. Iqondo lokushisa lomlilo lizinzile kwaye lilungelelaniswe, elilungele ukulawulwa ngokuchanekileyo koxinzelelo lomzobo.
C. Ukukhethwa kwamacandelo okufudumeza kwesithando somlilo kunye nokuyila ukuhamba komoya kuqinisekisa ukuba umphezulu we-fiber optical ungcolisekile kancinane kangangoko.
Ngoko ke, ukuphuculwa kwesakhiwo samacandelo esithandweni sokudweba ucingo kunye nokuphuculwa kwenkqubo yokuphuma komoya kwisithando somlilo.Ufumene ezi ziphumo zilandelayo:
A. Ububanzi be-F ububanzi be-amplitude ye-fiber optical ye-ADSS ngexesha lenkqubo yokudweba ilawulwa ukuba ibe malunga ne-0.3 μm.
B. I-warpage ye-ADSS fibre optic cable kufuneka ilawulwe ngaphezu kwe-10m
C, i-ADSS ifayibha ye-optical ineempawu ezilungileyo zokuthomalalisa zobude obungangelanga
2. I-Optical fibre coating ye-ADSS optical cable
Ukwambathisa kuyinkqubo ekhethekileyo ebaluleke kakhulu kwimveliso ye-ADSS fiber optical.Umgangatho wokugquma unempembelelo enkulu kumandla kunye nokulahleka kwefiber optical.I-fiber engenanto ingena kwi-mold ngesantya esiphezulu kwaye itsalwa kulwelo lokugquma.Ekubeni i-fiber ngokwayo inobushushu, i-viscosity ye-coating phezulu kwi-mold iphantsi kune-viscosity ye-coating kwi-tank yokugqoka.Lo mahluko kwi-viscosity phakathi kweepeyinti kudala umahluko woxinzelelo otyhala ipeyinti phezulu.Uxinzelelo oluthile lokugquma lusetyenziselwa ukugcina uzinzo lwenqanaba le-coating liquid kwi-mold.Ukuba ubushushu befiber engenanto buphezulu kakhulu (ukwandisa isantya sokudweba ucingo), ibhalansi yenqanaba le-coating fluid iya kuba ingalawulekiyo, i-coating iya kuba ingazinzile, kwaye i-coating iya kuba yinto engavamile.Ichaphazela umgangatho wokugquma kunye nokusebenza kwefiber.Umgangatho olungileyo wokugquma ozinzileyo kufuneka ubandakanye le miba ilandelayo:
A. Akukho amaqamza okanye ukungcola kwi layer yokwambathisa;
B. Ukujongwa kakuhle kokugquma;
C. Ukutshintsha kwedamitha encinci yokwaleka.
Ngaphantsi kweemeko zomzobo wesantya esiphezulu, ukuze kufumaneke umgangatho wokugcoba ochanekileyo kunye nozinzile, i-fiber kufuneka igcinwe kwindawo yokushisa ephantsi kunye neyoneleyo (ngokuqhelekileyo ithathwa njenge-50 ° C) xa ingena kwi-coating die.Ngokunyuka kwesantya somzobo, amathuba okuxuba umoya kwi-coating xa i-fiber ifakwe iphuculwe kakhulu.Kwangaxeshanye, ngexesha lomzobo wocingo olukhawulezayo, ukunyanzeliswa komzobo wocingo nako kuphuculwe kakhulu.Ukusebenzisana phakathi kwamandla e-centripetal eyenziwa yi-coating die kunye ne-wire drawing tension imisela ukuzinza kwimeko yokwaleka.Oku kufuna ukusetyenziswa kwedayithi enokuvelisa amandla aphezulu e-centripetal kunye nenkqubo yohlengahlengiso lwe-engile yokufa echaneke ngakumbi ukuze kuqinisekiswe uzinzo lokugquma ngexesha lomzobo wocingo olukhawulezayo.
Emva komzobo onesantya esiphezulu somzobo we-ADSS optical fiber, le nto ilandelayo ye-fiber optical optical ityabeka kakuhle yenzeka:
A. I-diameter ye-coating itshintsha kakhulu kwaye i-eccentricity ye-coating ihlwempuzekile ngexesha lokudweba ucingo.
B, ukutyabeka kunamaqamza
C. Ukwahlukana phakathi kokwaleka kunye nokugquma
Ukunyangwa kokutyabeka okulambathayo, okufana nokwenza ngcono ukugquma ngezinye zezi nkqubo zilandelayo zophuculo kunye nohlengahlengiso lwezixhobo:
A. Kwimbono yotshintsho olukhulu lwedayamitha yokwaleka, lungiselela inkqubo yokwaleka, kwaye ekugqibeleni wenze utshintsho lweamplitude yokwambathisa ububanzi kunye nokugxila kokugquma ukufikelela kwimeko efanelekileyo.
B. Ngamaqamza kwi-coating, lungisa isixhobo sokupholisa kwaye uguqule ukusebenza kakuhle kokupholisa, ukwenzela ukuba i-fiber engenanto inokucoliswa ngokufanayo kunye nefuthe elihle ngexesha lokuvelisa.
C. Kunyango olulambathayo lokwaleka kunye ne-delamination phakathi kokwaleka kunye nokugquma.Inkqubo yokunyanga ye-UV emva kokugquma kwe-fiber optical iphuculwe ukufezekisa ukuqina komoya okugqwesileyo;ukubekwa kwenkqubo elungisiweyo iqinisekisa indawo yefiber optical xa iphiliswa kwi-UV yokunyanga i-quartz tube.
Emva kokuphuculwa okungentla kweeparameters zenkqubo efanelekileyo kunye nezibonelelo, umgangatho obalaseleyo wokugquma ufunyenwe ukuqinisekisa ukuzinza nokuthembeka kwe-ADSS optical fiber performance.
