1. Optical fiber ntau zaus bandwidth.
Qhov dav ntawm pawg zaus sawv cev rau qhov loj ntawm lub peev xwm kis tau. Qhov ntau dua qhov nquag ntawm cov cab kuj, ntau dua qhov bandwidth ntawm cov teeb liab uas tuaj yeem kis tau. Hauv VHF zaus band, cov khoom xa khoom tsawg zaus yog 48.5MHz ～ 300Mhz.
2. Optical fiber muaj qhov muaj zog los tiv thaiv kev cuam tshuam cov peev xwm.
Vim tias qhov pib sib xyaw ntawm cov kho qhov muag yog quartz, nws tsuas yog xa teeb, tsis ua hluav taws xob, thiab tsis cuam tshuam los ntawm hluav taws xob teb. Lub teeb liab kis tau kis hauv nws tsis cuam tshuam los ntawm hluav taws xob teb. Yog li no, cov kis tau tus mob fiber ntau tau muaj zog tiv taus electromagnetic cuam tshuam thiab kev cuam tshuam hauv chaw lag luam.
3. Lub teeb meem kev teeb tsa ntawm cov khoom siv fiber ntau yog tsawg dua ntawm lub network cable.
Txoj kab uas hla ntawm ib hom kho qhov muag fiber core hlau feem ntau yog 4um ～ 10um, thiab cov cheeb sab nraud tsuas yog 125um. Nrog cov txheej txheem dej tsis ua haujlwm, ntxiv dag zog sib dhos, hnab riam, thiab lwm yam, cov kab uas hla ntawm kab hluav taws xob muaj 4 ～ 48 optical fiber ntau me dua 13 hli, uas tsawg dua li cov qauv coaxial cable Txoj kab uas hla ntawm 47 hli tau me dua, thiab cov fiber ntau kho qhov muag yog iav fiber ntau, uas muaj lub zog sib tsoo tshwj xeeb, uas ua rau nws muaj cov yam ntxwv ntawm txoj kab uas hla me me thiab lub teeb nyhav, thiab nws yooj yim heev rau kev txhim kho.
4. Qhov poob ntawm optical fiber yog tsawg.
Nws muaj qhov poob zoo ib yam hauv txhua qhov cable TV TV, thiab tsis tas yuav qhia qhov sib luag rau kev sib luag sib luag zoo li cov kab hluav taws xob cable; nws poob tsis pauv nrog qhov kub, thiab tsis tas yuav txhawj xeeb txog kev hloov pauv hauv cov nqaj theem vim yog qhov hloov pauv ntawm qhov kub ib puag ncig.
5. Optical fiber kis tau zoo dua qub kev ntseeg tau.
Vim tias kis tau tus kab mob fiber ntau feem ntau tsis xav tau kev xa xov txuas ntxiv, nws yuav tsis qhia qhov tshiab tsis suav hloov dua tshiab vim yog ua kom nrov nrov. Ntev npaum li qhov ntev ntawm txoj kab ntawm lub laser tau zoo, lub teeb liab TV yuav kis tau nrog lub siab ncaj ncees. Vim tias cov kaw lus fiber ntau muaj cov khoom siv me me, kev ntseeg tau yog ib txwm muaj.
