Cov xov hluav taws xob fiber optic tau dhau los ua lub hauv paus ntawm cov kab ke sib txuas lus niaj hnub no. Kev ua tau zoo thiab kev ruaj khov ntawm cov xov hluav taws xob no yog qhov tseem ceeb rau kev ntseeg tau thiab zoo ntawm cov tes hauj lwm sib txuas lus. Cov ntaub ntawv siv hauv cov xov hluav taws xob no ua lub luag haujlwm tseem ceeb hauv kev ua kom lawv tuaj yeem tiv taus qhov chaw ib puag ncig hnyav thiab muab kev sib kis ruaj khov rau lub sijhawm ntev.
Ib yam khoom siv uas tau txais kev saib xyuas hauv kev lag luam yog Polybutylene Terephthalate (PBT). Cov khoom siv PBT muaj cov yam ntxwv zoo heev ntawm kev kho tshuab, hluav taws xob, thiab cua sov uas ua rau lawv tsim nyog rau kev siv hauv cov xov hluav taws xob optical fiber. Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov khoom siv PBT yog lawv qhov kev nqus dej tsawg, uas muaj feem cuam tshuam loj rau kev ruaj khov thiab kev ua haujlwm ntev ntawm cov xov hlau.
Kev nqus dej noo hauv cov cables tuaj yeem ua rau muaj ntau yam teeb meem, suav nrog kev txo qis ntawm lub teeb liab, qhov hnyav ntawm cable, thiab lub zog tensile txo qis. Dej noo kuj tseem tuaj yeem ua rau xeb thiab puas tsuaj rau cable dhau sijhawm. Txawm li cas los xij, cov ntaub ntawv PBT qhia txog qhov nqus dej tsawg, uas pab txo cov teeb meem no thiab txhim kho kev ruaj khov thiab kev ua haujlwm ntev ntawm cov cables.
Cov kev tshawb fawb tau qhia tias cov ntaub ntawv PBT tuaj yeem nqus tau tsawg li 0.1% cov dej noo hauv qab qhov xwm txheej ib txwm muaj. Qhov kev nqus dej noo qis no pab tswj cov khoom siv kho tshuab thiab hluav taws xob ntawm lub cable dhau sijhawm, tiv thaiv kev puas tsuaj lossis kev puas tsuaj rau lub cable. Tsis tas li ntawd, cov ntaub ntawv PBT muab kev tiv thaiv zoo heev rau cov tshuaj lom neeg, hluav taws xob UV, thiab qhov kub thiab txias heev, ua rau lub cable ruaj khov thiab ua haujlwm tau zoo dua.
Xaus lus, qhov nqus dej tsawg ntawm cov ntaub ntawv PBT ua rau lawv yog qhov kev xaiv zoo tshaj plaws rau kev siv hauv cov xov hlau fiber ntau. Los ntawm kev muab kev ruaj khov thiab kev ua haujlwm ntev dua, cov ntaub ntawv PBT tuaj yeem pab ua kom muaj kev ua haujlwm zoo ntawm cov tes hauj lwm sib txuas lus. Raws li qhov kev thov rau cov kab ke sib txuas lus zoo txuas ntxiv mus, kev siv cov ntaub ntawv PBT yuav nce ntxiv, ua rau nws yog cov khoom siv zoo rau kev lag luam cable.
