Kev Siv Cov Fibers Uas Nqus Dej Hauv Cov Cables Optical thiab Cov Cables Fais Fab

Thaum lub sijhawm ua haujlwm ntawm cov xov hluav taws xob thiab cov xov hluav taws xob, qhov tseem ceeb tshaj plaws uas ua rau kev ua haujlwm poob qis yog qhov dej nkag mus. Yog tias dej nkag mus rau hauv cov xov hluav taws xob, nws tuaj yeem ua rau cov fiber attenuation ntau ntxiv; yog tias nws nkag mus rau hauv cov xov hluav taws xob, nws tuaj yeem txo qhov kev ua haujlwm rwb thaiv tsev ntawm cov xov hluav taws xob, cuam tshuam rau nws txoj haujlwm. Yog li ntawd, cov khoom thaiv dej, xws li cov khoom siv nqus dej, tau tsim rau hauv cov txheej txheem tsim cov xov hluav taws xob thiab cov xov hluav taws xob kom tiv thaiv cov dej nkag mus lossis dej, kom ntseeg tau tias muaj kev nyab xeeb hauv kev ua haujlwm.

Cov khoom tseem ceeb ntawm cov khoom siv nqus dej suav nrog cov hmoov nqus dej,daim kab xev thaiv dej, cov xov thaiv dej, thiab cov roj nplaum uas thaiv dej o, thiab lwm yam. Nyob ntawm qhov chaw siv, ib hom khoom thaiv dej yuav siv tau, lossis ntau hom sib txawv yuav siv tau tib lub sijhawm kom ntseeg tau tias cov cables ua haujlwm tsis pub dej nkag.

Nrog rau kev siv thev naus laus zis 5G sai sai, kev siv cov xov hluav taws xob optical tau dhau los ua qhov dav dua, thiab cov kev cai rau lawv tau dhau los ua qhov nruj dua. Tshwj xeeb tshaj yog nrog kev qhia txog kev tiv thaiv ntsuab thiab kev tiv thaiv ib puag ncig, cov xov hluav taws xob optical qhuav tag nrho tau txais kev nyiam los ntawm kev ua lag luam. Ib qho tseem ceeb ntawm cov xov hluav taws xob optical qhuav tag nrho yog tias lawv tsis siv cov roj txhaws dej lossis cov roj txhaws dej o. Hloov chaw, daim kab xev thaiv dej thiab cov fibers thaiv dej siv rau kev thaiv dej thoob plaws tag nrho ntawm cov xov hluav taws xob.

Kev siv cov ntaub nplaum thaiv dej hauv cov cables thiab optical cables yog ib qho uas siv ntau heev, thiab muaj ntau cov ntaub ntawv tshawb fawb txog nws. Txawm li cas los xij, muaj tsawg dua kev tshawb fawb qhia txog cov xov hlau thaiv dej, tshwj xeeb tshaj yog rau cov ntaub ntawv fiber thaiv dej uas muaj cov khoom nqus dej zoo heev. Vim lawv yooj yim them rov qab thaum lub sijhawm tsim cov optical thiab hluav taws xob cables thiab kev ua yooj yim, cov ntaub ntawv fiber nqus dej zoo heev tam sim no yog cov ntaub ntawv thaiv dej nyiam hauv kev tsim cov cables thiab optical cables, tshwj xeeb tshaj yog cov optical cables qhuav.

Daim Ntawv Thov Hauv Kev Tsim Khoom Siv Hluav Taws Xob

Nrog rau kev txhim kho tas mus li ntawm Tuam Tshoj txoj kev tsim kho vaj tse, qhov kev thov rau cov xov hluav taws xob los ntawm cov phiaj xwm txhawb nqa hluav taws xob txuas ntxiv mus ntxiv. Cov xov hluav taws xob feem ntau raug teeb tsa los ntawm kev faus ncaj qha, hauv cov qhov cable, qhov av, lossis cov txheej txheem saum toj kawg nkaus. Lawv yeej tsis zam nyob rau hauv qhov chaw noo noo lossis sib cuag ncaj qha nrog dej, thiab tej zaum yuav raug muab tso rau hauv dej luv luv lossis ntev, ua rau dej maj mam nkag mus rau hauv sab hauv ntawm cov xov hluav taws xob. Nyob rau hauv qhov kev ua ntawm lub teb hluav taws xob, cov qauv zoo li ntoo tuaj yeem tsim nyob rau hauv cov txheej rwb thaiv tsev ntawm tus neeg coj, ib qho xwm txheej hu ua dej tsob ntoo. Thaum cov ntoo dej loj hlob mus rau qee qhov, lawv yuav ua rau lub rwb thaiv tsev ntawm cov xov hluav taws xob tawg. Dej tsob ntoo tam sim no tau lees paub thoob ntiaj teb tias yog ib qho ntawm cov laj thawj tseem ceeb ntawm kev laus ntawm cov xov hluav taws xob. Txhawm rau txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm lub kaw lus muab hluav taws xob, kev tsim qauv cable thiab kev tsim khoom yuav tsum siv cov qauv thaiv dej lossis cov txheej txheem tiv thaiv dej kom ntseeg tau tias cov xov hluav taws xob muaj kev ua tau zoo thaiv dej.

Cov kev nkag mus rau hauv cov cables feem ntau tuaj yeem muab faib ua ob hom: radial (lossis transverse) nkag mus rau hauv lub sheath, thiab longitudinal (lossis axial) nkag mus rau hauv tus neeg xyuas pib thiab lub cable core. Rau radial (transverse) dej thaiv, ib lub sheath thaiv dej dav dav, xws li daim kab xev txhuas-yas sib xyaw ua ke longitudinal qhwv thiab tom qab ntawd extruded nrog polyethylene, feem ntau siv. Yog tias xav tau tag nrho radial dej thaiv, ib lub qauv hlau sheath raug saws. Rau cov cables feem ntau siv, kev tiv thaiv dej thaiv tsom mus rau qhov longitudinal (axial) dej nkag mus.

Thaum tsim cov qauv cable, cov kev ntsuas dej yuav tsum xav txog qhov tsis kam dej hauv qhov ntev (lossis axial) ntawm tus neeg xyuas pib, kev tsis kam dej sab nraum cov txheej rwb thaiv tsev, thiab kev tsis kam dej thoob plaws tag nrho cov qauv. Txoj kev dav dav rau cov neeg xyuas pib thaiv dej yog sau cov khoom thaiv dej sab hauv thiab ntawm qhov chaw ntawm tus neeg xyuas pib. Rau cov cables hluav taws xob siab nrog cov neeg xyuas pib faib ua cov ntu, cov xov hlau thaiv dej raug pom zoo kom siv ua cov khoom thaiv dej hauv nruab nrab, raws li pom hauv Daim Duab 1. Cov xov hlau thaiv dej kuj tseem tuaj yeem siv rau hauv cov qauv thaiv dej tag nrho. Los ntawm kev muab cov xov hlau thaiv dej lossis cov hlua thaiv dej uas xaws los ntawm cov xov hlau thaiv dej rau hauv qhov sib txawv ntawm ntau yam khoom ntawm cable, cov channel rau dej ntws raws qhov axial ntawm cable tuaj yeem raug thaiv kom ntseeg tau tias cov kev cai nruj dej ntev tau ua tiav. Daim duab qhia txog cov cable thaiv dej tag nrho yog pom hauv Daim Duab 2.

Hauv cov qauv cable uas tau hais los saum toj no, cov khoom siv fiber uas nqus dej tau siv ua chav thaiv dej. Lub tshuab no vam khom cov resin nqus dej ntau heev uas muaj nyob rau ntawm qhov chaw ntawm cov khoom siv fiber. Thaum ntsib dej, cov resin nthuav dav sai sai mus rau 十几 txog 几十 npaug nws qhov ntim thawj, tsim ib txheej thaiv dej kaw rau ntawm qhov seem ntawm lub cable core, thaiv cov dej nkag mus, thiab tiv thaiv kev sib kis thiab kev nthuav dav ntawm dej lossis dej pa dej raws txoj kev ntev, yog li tiv thaiv lub cable tau zoo.
