Qhov zoo ntawm Yas Optic Fiber

2022-04-15 IB

Polymer Optical fiber (POF) yog ib qho Optical Fiber uas muaj cov khoom siv siab refractive index polymer li fiber core thiab tsawg refractive index polymer khoom raws li cladding. Zoo li quartz optical fiber, cov yas kho qhov muag fiber ntau kuj siv tag nrho cov kev xav ntawm lub teeb. Optical fiber core yog lub teeb ntom nruab nrab thiab cov cladding yog lub teeb ntom nruab nrab. Nyob rau hauv txoj kev no, ntev npaum li lub kaum sab xis ntawm lub teeb nkag mus yog qhov tsim nyog, lub teeb ntawm lub teeb yuav raug cuam tshuam tsis tu ncua hauv cov fiber ntau optical thiab xa mus rau lwm qhov kawg.

Qhov zoo ntawm cov yas optical fiber ntau

Kev sib txuas lus fiber ntau muaj peb qhov zoo dua li kev sib txuas lus hluav taws xob (tooj liab) cable: thawj, muaj peev xwm sib txuas lus loj; Thib ob, nws muaj kev cuam tshuam zoo electromagnetic cuam tshuam thiab kev ua haujlwm tsis pub lwm tus paub; Thib peb, nws yog lub teeb hauv qhov hnyav thiab tuaj yeem txuag tau ntau ntawm tooj liab. Piv txwv li, tso 1000 km ntev 8-core optical cable tuaj yeem txuag tau 1100 tons ntawm tooj liab thiab 3700 tons ntawm txhuas dua li tso 8-core cable ntawm tib qhov ntev. Yog li ntawd, thaum lub optical fiber ntau thiab kho qhov muag cable tawm, nws tau txais tos los ntawm kev sib txuas lus kev lag luam, uas coj ib tug kiv puag ncig nyob rau hauv kev sib txuas lus teb thiab ib puag ncig ntawm peev thiab kev loj hlob upsurge. Txawm hais tias quartz (iav) kho qhov muag fiber ntau muaj qhov zoo li hais saum toj no, nws muaj qhov tsis muaj zog txaus: tsis muaj zog, tsis muaj zog flexural tsis zoo thiab tsis muaj hluav taws xob tsis zoo.

Piv nrog quartz optical fiber, yas optical fiber yog ib qho ntawm cov ntaub ntawv rau kev lag luam ntaub ntawv nrog theoretical kev tshawb fawb tseem ceeb thiab daim ntawv thov kev cia siab nyob rau hauv lub teb ntawm Polymer Science nyob rau hauv 20 xyoo tsis ntev los no. Nws muaj cov yam ntxwv hauv qab no:

(1) Txoj kab uas hla yog loj, feem ntau mus txog 0.5 ~ 1mm. Cov tub ntxhais loj fiber ntau ua rau nws txoj kev sib txuas yooj yim thiab yooj yim rau kev sib dhos, kom cov khoom siv hluav taws xob pheej yig tuaj yeem siv tau thiab cov nqi teeb tsa tsawg heev;

(2) Tus lej aperture (NA) yog qhov loj, txog 0.3 ~ 0.5, thiab kev sib txuas ua haujlwm nrog lub teeb pom kev zoo thiab cov cuab yeej txais tau siab;

(3) Cov qauv siv hluav taws xob muaj qhov zoo ntawm cov khoom pheej yig, cov nqi tsim khoom tsawg thiab kev siv dav.
