Basic Structure Ntawm Optical Fiber Cables

Optical fiber cables feem ntau muaj cov tub ntxhais, cladding, thiab txheej. Cov tub ntxhais, nyob rau hauv nruab nrab ntawm cov fiber ntau, yog thawj channel rau optical teeb liab kis tau tus mob. Nws feem ntau yog ua los ntawm siab - purity silicon dioxide (SiO₂), muaj lub teeb xa hluav taws xob tsis tshua muaj siab thiab kho qhov muag teeb pom kev zoo. Lub cladding nruj nreem qhwv nyob ib ncig ntawm lub hauv paus, nrog ib tug me ntsis qis refractive index tshaj lub tub ntxhais, kom tag nrho cov sab hauv xav txog ntawm lub optical teeb liab nyob rau hauv lub tub ntxhais, yog li ua kom ntev - kis tau tus mob. Cov txheej, nyob rau ntawm txheej txheej sab nraud ntawm cov fiber ntau, feem ntau ua haujlwm tiv thaiv, tiv thaiv kev puas tsuaj los ntawm ib puag ncig sab nraud.
