Fiber Optic Preform: Ib Qhuab Qhia, Kws Tsim Khoom -}} Tus phooj ywg sib sib zog nqus
Yog koj nkag siab li cas aFiber ntau Optic Preformyog teev, tau ua, thiab kuaj xyuas kos duab, koj tuaj yeem kwv yees kos duab, thiab kev cia siab, thiab kev ua haujlwm ua ntej ntauwd sov. Hauv phau ntawv qhia no, peb unppack cov tswv yim tseem ceeb, muab cov txheej txheem sib piv (ovd, tus lej, thiab muab cov ntawv txheeb xyuas, thiab muab cov ntawv txheeb xyuas, thiab muab cov lej cim, thiab muab cov lej sau ntawv, thiab muab cov lej lej, thiab muab cov lej lej, thiab muab cov lej sau ntawv, thiab muab cov lej lej, thiab muab cov lej lej, thiab muab cov lej cim, thiab muab cov lej lej, thiab cov cuab yeej siv nyiaj rau koj
Vim li cas "preform - ua ntej xav" hloov koj cov txiaj ntsig
Ib txoj kab tsuas yog zoo li nwstshiabCov. Daim ntawv qhia iav iav, soot ntom ntom, lub cev qhuav dej, thiab kev sib xyaw ua ke keeb kwm teeb tsa, thiab cov kev kho kom zoo rau ntawm 1310 thiab 1550 nm. Thaum lub billet yog txoj cai, cov fiber ntau cov roj nrog lub caj dab ruaj khov {}} pa, thiab cabpab khoom raws li kev tsis muaj suab nrov. Thaum nws tsis yog lawm, koj sib ntaus sib tawg, micro - khoov, thiab ib pawg ntawm daim pib ua haujlwm.
Cov kws ua engineers tswj peb lub levers thaum ntxov:kev coj dawb huv, sab ntawm, thiabNTSIAB LUSCov. Kev ua tub sab tsis huv tswj hwm huag peaks thiab ntev-} term hydrogen cuam tshuam. Profile tswj ntawm na, khoov poob, thiab dispersion. Geometry tswj kos kos duab kev ruaj khov thiab txheej centtricity. Xauv cov nqes, thiab cov teeb meem ntws hauv cov teeb meem hauv qab.
Nkag Siab Lub Fiber Optic Preform (Core Cov Ntsiab Lus)
Dab tsi nws yog fiber ntau preform
Ib qho Preform yog ib khob iav cylindrical uas nwsRadial Performance index profilethiab cov qib impurity tau ua kom zoo li ntawd, thaum koj caj dab nws hauv ib qho kev tsim tawm {} Geometry, NA, thiab AIDEATED. Lub billet pib ua ib qho ntxeem tau "soot" lub cev uas ua rau muaj tseeb, lossis ua cov kab tuab tuab ua hauv qab.
Vim li cas o huag teeb meem.
