I. Cov Ntsiab Cai ntawm Fiber Optic Cables

1. Cov qauv thiab cov khoom ntawm Fiber Optic Cables

Fiber optic cables muaj ib tug complex qauv suav nrog ntau txheej txheej, txhua qhov ua haujlwm tshwj xeeb. Ntawm lub hauv paus ntawm lub cable yog cov fiber ntau, feem ntau yog ua los ntawm iav los yog yas, los ntawm cov teeb liab mus. Nyob ib ncig ntawm lub hauv paus yog lub cladding, ib txheej nrog ib tug qis refractive index uas pab confine lub teeb nyob rau hauv lub tub ntxhais. Lub cladding feem ntau yog ua los ntawm cov khoom sib txawv dua li cov tub ntxhais kom ua tiav qhov ntsuas qhov sib txawv ntawm qhov sib txawv.

Txhawm rau ua kom lub cev muaj kev ncaj ncees thiab kev tiv thaiv ntawm cov khoom siv fiber ntau, lub tsho tiv thaiv ua los ntawm cov khoom siv ruaj khov xws li polyethylene lossis PVC encases cladding. Lub tsho no tiv thaiv cov fiber ntau los ntawm cov khoom siv sab nraud, xws li ya raws, tshuaj lom neeg, thiab kev ntxhov siab ntawm lub cev, khaws cia nws cov kev ua tau zoo thiab kev ua haujlwm ntev.

2. Txoj Cai ntawm Tag Nrho Internal Reflection

Kev xa cov teeb liab teeb liab nyob rau hauv fiber ntau optic cables nyob ntawm lub hauv paus ntsiab lus ntawm tag nrho cov sab hauv xav txog. Thaum lub teeb ntsib tus ciam teb ntawm cov tub ntxhais thiab cladding ntawm lub kaum sab xis siab dua lub kaum sab xis tseem ceeb, nws rov qab mus rau hauv cov tub ntxhais es tsis txhob thim tawm los ntawm cladding. Qhov kev xav sab hauv tag nrho no tshwm sim vim qhov hloov pauv ntawm qhov ntsuas qhov ntsuas ntawm qhov tseem ceeb thiab cladding.

Nco ntsoov, fiber ntau optic cables muaj kev ua tau zoo dua, tiv thaiv kev cuam tshuam ntawm electromagnetic, thiab muaj peev xwm xa cov ntaub ntawv mus ntev. Los ntawm kev txhawb nqa fiber ntau optics, koj tuaj yeem pab txhawb kev txhawb nqa kev sib txuas lus niaj hnub thiab nyob ntawm qhov ua ntej ntawm kev sib txuas.

Ua tsaug rau koj tuaj koom peb ntawm kev taug kev no los ntawm lub ntiaj teb ntawm fiber ntau optic cables. Cia peb txuas ntxiv mus tshawb txog lub qab ntug tshiab thiab tuav lub zog ntawm fiber ntau optics hauv kev tsim lub neej yav tom ntej ntawm kev sib txuas lus.
