1. Qhov txawv ntawm lub tswv yim ntawm optical cable thiab optical fiber ntau:
Lub npe tag nrho ntawm optical fiber yog hu ua optical fiber, uas yog kos los ntawm cov ntshiab quartz nrog cov txheej txheem tshwj xeeb rau hauv lub iav raj thinner dua tib neeg cov plaub hau nrog ob peb xov xwm hauv nruab nrab. Nws qhov kev ntxhib los mos yog nkig thiab yooj yim tawg, yog li yuav tsum muaj kev tiv thaiv ntxiv.
Cov kab hluav taws xob kho qhov muag feem ntau yog tsim los ntawm cov khoom siv kho qhov muag, cov tes tsho tiv thaiv yas thiab cov hnab yas. Cov qauv kev tiv thaiv ntawm txheej txheej tuaj yeem tiv thaiv kev puas tsuaj ntawm cov khoom siv kho qhov muag los ntawm ib puag ncig ib puag ncig.
Fiber optic cables muaj fiber ntau optical thiab yog ib feem ntawm fiber ntau optic cable. Optical fiber ntau yog cov iav fiber ntau hauv cov khoom siv kho qhov muag, tab sis cov ntawv luv ntawm ob feem ntau tsis nruj me ntsis txawv hauv kev siv engineering.
2. Qhov txawv ntawm optical cable thiab optical fiber qauv:
Optical fiber ntau yog muab faib ua ob pawg, ib qho yog graded optical fiber, thiab lwm yam yog stepped optical fiber. Lub refractive index ntawm lub qub yog graded, thaum lub refractive index ntawm lub tom kawg yog abrupt.
Cov kab hluav taws xob kho qhov muag feem ntau yog tsim los ntawm cov khoom siv kho qhov muag, cov tes tsho tiv thaiv yas thiab cov hnab yas. Tsis muaj cov hlau xws li kub, nyiaj, tooj liab thiab txhuas hauv cov khoom siv kho qhov muag, thiab feem ntau lawv tsis muaj nqi rov ua dua.
3. Qhov sib txawv ntawm kev nthuav tawm kev ua haujlwm ntawm optical cable thiab optical fiber ntau:
Optical fiber ntau, cov kws tshawb fawb tau tsim "Internal adhesion method", "MCVD method", "VAD method" los ua ultra-high-purity quartz iav, thiab qhov ua tau zoo ntawm lub teeb kis tau tus mob tshwj xeeb ntawm cov khoom siv kho qhov muag tau zoo tuaj.
Optical cable, kev sib txuas lus kho qhov muag cable yog ib hom kev sib txuas lus kab uas muaj qee tus xov tooj ntawm cov khoom siv kho qhov muag tsim cov tub ntxhais cable raws li ib txoj hauv kev, uas yog them nrog lub sheath, thiab qee qhov kuj tau them nrog lub tsho sab nrauv kom paub txog kev sib kis. ntawm optical signals.
