Ua ntej tshaj plaws, qhov kho qhov muag cable tsis ntshai dej vim nws muaj kev tiv thaiv. Thaum cov khoom siv kho qhov muag hloov mus rau hauv ib lub cable, muaj ob qhov kev tiv thaiv uas yuav tsum tau ua rau cov khoom siv kho qhov muag: ib qho yog tias cov fiber ntau optical tsis tshua muaj kev ntxhov siab; Lwm qhov yog tias cov fiber ntau optical yuav tsum tsis muaj dej. Cov txheej txheej sab nraud ntawm cov khoom siv kho qhov muag yog lub hnab yas, sab hauv yog hlau sheath, thiab sab hauv yog cov dej thaiv cov txheej txheem uas swells nrog dej, thiab cov tub ntxhais ntawm lub cable yog glued nrog tshuaj pleev thiab kho qhov muag fibers.
Cov kab hluav taws xob kho qhov muag muaj plaub lub qhov rooj tsis muaj dej, uas yog: npog yas, hlau npog, dej thaiv txheej thiab tshuaj pleev.
Yog li lo lus nug yog, puas yog cov tub ntxhais fiber ntau ntshai dej? Tsis yog iav xwb, koj ntshai dej dab tsi?
Qhov tseeb, nws ntshai dej.
Tej zaum koj yuav xav tias yog vim li cas lub khob iav thiab lub qhov rais iav hauv tsev tsis ntshai dej tab sis tsis muaj dej, thiab vim li cas lawv txhua tus iav?
Vim li cas cov tub ntxhais fiber ntau ntshai dej?
Nws feem ntau ntseeg tias cov tub ntxhais fiber ntau tsis ntshai dej, vim tias iav muaj cov dej adhesion zoo heev. Tab sis qhov tseeb, dej muaj teeb meem heev rau optical cables. Yog tias dej nkag mus rau hauv qhov kho qhov muag cable, nws yuav ua rau cov khoom siv kho qhov muag puas thaum nws khov thiab nthuav dav hauv cov dej txias, yog li cov khoom siv kho qhov muag yuav tsum tau ntim cov tshuaj pleev kom tsis txhob ya raws los ntawm kev nkag mus.
Cov kev sim qhia tau hais tias qhov ntev ntawm cov dej noo nkag mus rau hauv cov kab hluav taws xob kho qhov muag yuav ua rau qhov poob ntawm cov khoom siv kho qhov muag, tshwj xeeb tshaj yog nyob rau ntawm 1.55 pm wavelength.
Yog vim li cas vim li cas fiber ntau optical ntshai dej yog qhov kho qhov muag fiber ntau yog tsim los ntawm iav (SiO4) silicon-oxygen tetrahedra txuas ua ke, raws li qhia hauv daim duab 1. Hauv Si-O-Si network, cov pa oxygen atoms muaj nyob rau hauv daim ntawv ntawm cov pa oxygen. choj.
Txawm li cas los xij, nyob rau hauv ib puag ncig dej, tom qab lub iav saum npoo adsorbs dej vapor, cov tshuaj tiv thaiv hydrolysis qeeb tshwm sim, ua rau tawg ntawm silicon-oxygen daim ntawv cog lus nyob rau hauv thawj-Si-O- network Yes-, thiab cov pa oxygen txuas ntxiv ua tsis muaj kev sib txuas cov pa oxygen raws li qhia hauv daim duab 2, ua rau cov kab nrib pleb hauv cov iav, thiab cov kab nrib pleb txuas ntxiv mus.
Seb nws yog ntses tank iav, qhov rais iav los yog fiber ntau optic iav, txhua leej txhua tus ntshai dej. Qhov txawv yog tias cov iav tank iav thiab qhov rais iav yog tuab heev, nrog thicknesses ntawm 3 hli, 5 hli thiab 10 hli. Txawm hais tias muaj qhov tawg ntawm 0.05mm, nws yuav tsis cuam tshuam rau lub zog ntawm lub khob.
Cov iav fiber ntau yog qhov sib txawv ntawm cov iav fiber ntau tsuas yog 0.125mm, uas yog tuab li cov plaub hau yog tias muaj qhov tawg ntawm 0.05mm, txoj kab uas hla ntawm fiber ntau yuav yog 0.075mm, yog li cov fiber ntau yog. Ib qho yooj yim heev kom tawg ntxiv, cov tsos ntawm OH cov hauv paus hniav tseem yuav ua rau kom lub teeb pom kev poob ntawm cov fiber ntau optical. Qhov no yog vim li cas ntses tank iav thiab qhov rais iav tsis ntshai dej, thaum fiber optic iav ntshai dej.
Nyob rau hauv cov ntaub ntawv no, yog hais tias tus kho qhov muag cable puas lawm, lub sealing ntawm lub hlws ris lub thawv tsis zoo thiab cov liab qab fiber ntau raug, lub neej kev pab cuam ntawm optical fiber yuav luv luv thiab fiber ntau yuav lawm vim dej.
Yog li ntawd, yog tias cov khoom siv kho qhov muag tau tsim nyob rau hauv cov kav dej phwj tuaj, cov pob qij txha yuav tsum tau ua kom zoo, thiab yog tias cov fiber ntau optical nws tus kheej puas lawm, nws yuav tsum tau kho. Tsis txhob cia sab hauv ntawm cov khoom siv kho qhov muag tuaj yeem tiv nrog dej.
