Fiber Optic vs. Fiber Optic Cable: Paub Qhov Txawv Tseem Ceeb. Koj puas tsis meej pem los ntawm "fiber optic" thiab "fiber optic cable"?

Fiber optics vs. Cov xov hlau fiber optic Optics: Paub qhov txawv tseem ceeb
Koj puas tsis nkag siab txog lo lus "fiber optic" thiab "fiber optic cable"? Koj tsis yog tib tug xwb. Cov lus no feem ntau siv sib pauv tau, tab sis kev nkag siab txog lawv cov haujlwm sib txawv yog qhov tseem ceeb rau txhua tus neeg ua haujlwm nrog kev sib txuas lus, network, lossis infrastructure. Cia peb piav qhia meej:

1. Fiber optics: Lub hauv paus thev naus laus zis

Nws yog dab tsi: Ib txoj hlua zoo nkauj heev ntawm cov iav ntshiab heev (lossis qee zaum yas), me ntsis tuab dua li cov plaub hau tib neeg.

Kev Ua Haujlwm: Nws yog lub teeb qhia kev, lub thev naus laus zis tshiab hauv nws tus kheej. Nws xa cov ntaub ntawv hauv daim ntawv ntawm lub teeb pulses hla qhov deb nrog qhov poob tsawg kawg nkaus, bandwidth siab, thiab tiv thaiv kev cuam tshuam electromagnetic (tsis zoo li tooj liab).

Lub ntsiab lus tseem ceeb: Nws yog raws li lub hauv paus ntsiab lus ntawm kev cuam tshuam sab hauv tag nrho. Cov teeb liab teeb liab tawm ntawm lub hauv paus / cladding interface thiab mus ncig los ntawm lub fiber nrog qhov ceev thiab ua haujlwm zoo kawg.

2. Cable Cov Khoom Siv Fiber OpticsLub Txheej Txheem Kev Tiv Thaiv

Nws yog dab tsi: Ib lub rooj sib dhos ruaj khov uas tsim los tiv thaiv, khi, thiab tswj ib lossis ntau lub fibers optical rau kev teeb tsa yooj yim thiab siv hauv cov chaw ib puag ncig hnyav.

Kev Ua Haujlwm: Tiv thaiv cov fiberglass mos mos los ntawm cov kev pheej hmoo tiag tiag xws li dej noo, lub zog tsoo, khoov, puas, nas, qhov kub thiab txias heev thiab kev puas tsuaj rau lub cev thaum lub sijhawm teeb tsa thiab thoob plaws nws lub neej kev pabcuam.

CoVIM LI CASCov ntsiab lus tseem ceeb:

Cov Fibers: Cov ntsiab lus tseem ceeb uas nqa lub teeb nyob hauv.

Cov Txheej Txheem Tiv Thaiv: Cov txheej yas tiv thaiv siv ncaj qha rau txhua lub fiber.

Cov Khoom Muaj Zog: Cov khoom siv tawv xws li cov xov aramid (Kevlar) lossis cov pas nrig fiberglass uas nqus tau qhov nruj, tiv thaiv cov fibers kom tsis txhob ncab.

Cable Sheath: Lub txheej sab nraud tawv (feem ntau yog PVC, LSZH, lossis polyethylene) uas muab kev tiv thaiv ib puag ncig thiab kev kho tshuab thawj zaug.

Cov Tshuaj Sib Xyaws: Cov gels lossis cov khoom qhuav uas tiv thaiv dej kom tsis txhob nkag mus.

Kev Tiv Thaiv (Xaiv Tau): Cov ntaub nplaum hlau lossis cov xov hlau rau kev tiv taus ntau dua rau kev sib tsoo thiab cov nas (feem ntau nyob rau hauv kev faus ncaj qha lossis cov xov hlau saum huab cua).

Vim li cas qhov sib txawv thiaj li tseem ceeb?

Kev Ua Tau Zoo vs. Kev Tiv Thaiv: Cov fiber optics ua rau muaj kev xa cov ntaub ntawv ceev ceev. Lub cable ua kom ntseeg tau tias qhov kev ua tau zoo no tsis raug cuam tshuam los ntawm cov yam sab nraud. Lub cable puas tuaj yeem rhuav cov fibers sab hauv uas tsis muaj zog, cuam tshuam cov teeb liab.

Cov Kev Xaiv Tsim: Hom fiber (ib hom / multimode) txiav txim siab qhov bandwidth thiab qhov deb. Kev tsim kho cable (sab hauv tsev, sab nraum zoov, tiv thaiv, huab cua, duct) txiav txim siab nws qhov kev tsim nyog rau qhov chaw teeb tsa.

Kev Teeb Tsa thiab Kev Txij Nkawm: Cov kws kho tshuab ua cov cables, tsis yog cov fibers liab qab. Tus qauv tsim cable qhia txog cov txheej txheem tso, cov kev txwv ntawm qhov khoov, thiab cov txheej txheem xaus.
