Tom qab xyoo ntawm txoj kev loj hlob, kev tsim technology ntawm optical cables tau dhau los ua neeg paub tab. Ntxiv rau cov yam ntxwv zoo ntawm cov ntaub ntawv muaj peev xwm loj thiab kev sib kis tau zoo, cov khoom siv kho qhov muag kuj yuav tsum muaj qhov zoo ntawm qhov me me thiab lub teeb yuag. Cov yam ntxwv ntawm cov kab hluav taws xob kho qhov muag zoo sib xws nrog kev ua tau zoo ntawm cov khoom siv kho qhov muag, cov qauv tsim ntawm cov khoom siv kho qhov muag thiab cov txheej txheem tsim khoom, thiab tseem muaj feem cuam tshuam nrog ntau yam ntaub ntawv thiab cov khoom uas tsim los ntawm optical cable.
Ntxiv nrog rau cov fibers optical, cov ntaub ntawv tseem ceeb hauv cov khoom siv kho qhov muag muaj xws li peb pawg:
1. Cov Khoom Siv Hluav Taws Xob: Rub cov raj tso rau hauv cov raj, pev cov khoom siv raj, pur
2. Cov khoom siv sib xyaw: aluminium-yas composite daim kab xev, steel-yas composite daim kab xev
3. Cov khoom siv hlau: steel hlau
Niaj hnub no peb tham txog cov yam ntxwv ntawm cov khoom tseem ceeb hauv cov khoom siv kho qhov muag cable thiab cov teeb meem uas yuav tshwm sim, vam tias yuav pab tau rau cov tuam txhab kho qhov muag cable.
1. Tight tube khoom
Feem ntau ntawm cov ntaub ntawv nruj thaum ntxov yog siv cov nylon. Qhov zoo dua yog tias nws muaj qee lub zog thiab hnav tsis kam. Qhov tsis zoo yog tias cov txheej txheem kev ua haujlwm tsis zoo, kev ua haujlwm kub yog nqaim, nws yooj yim los tswj, thiab tus nqi siab. Tam sim no, muaj ntau dua cov khoom zoo thiab cov nqi qis dua, xws li hloov kho PVC, elastomers, thiab lwm yam. Los ntawm txoj kev loj hlob ntawm qhov pom, cov nplaim hluav taws kub hnyiab thiab cov khoom siv tsis muaj halogen yog qhov kev hloov tsis tau ntawm cov ntaub ntawv kaw ntom nti. Optical cable manufacturers yuav tsum tau them sai sai rau qhov no.
2. PBT xoob tube khoom
PBT yog dav siv nyob rau hauv lub xoob tube khoom ntawm optical fiber vim nws zoo heev mechanical zog thiab tshuaj tiv thaiv. Ntau ntawm nws cov khoom muaj feem cuam tshuam nrog qhov hnyav molecular. Thaum qhov hnyav molecular loj txaus, lub zog tensile, lub zog flexural, kev cuam tshuam lub zog siab. Hauv kev tsim khoom thiab siv tiag tiag, yuav tsum tau them nyiaj rau kev tswj xyuas qhov kev sib tw them nyiaj thaum lub sij hawm cable.
3. Filling tshuaj pleev
Optical fiber ntau yog rhiab heev rau OH-. Dej thiab dej noo yuav nthuav tawm cov micro-cracks ntawm qhov chaw ntawm cov khoom siv kho qhov muag, uas ua rau muaj qhov txo qis hauv lub zog ntawm cov khoom siv kho qhov muag. Cov hydrogen tsim los ntawm cov tshuaj tiv thaiv ntawm cov dej noo thiab cov khoom siv hlau yuav ua rau hydrogen poob ntawm cov fiber ntau optical thiab cuam tshuam rau qhov zoo ntawm fiber ntau optical cable. Yog li ntawd, hydrogen evolution yog ib qho tseem ceeb qhia txog tshuaj pleev.
4. Dej thaiv kab xev
Cov dej thaiv daim kab xev siv cov nplaum nplaum los ua kom cov dej nqus dej ntawm ob txheej ntawm cov ntaub tsis-woven. Thaum cov dej nkag mus rau sab hauv ntawm cov khoom siv kho qhov muag, cov dej-nqus resin yuav nqus dej sai sai thiab nthuav dav, ua kom qhov khoob ntawm cov khoom siv kho qhov muag, yog li tiv thaiv cov dej ntws los ntawm longitudinally thiab radially nyob rau hauv lub cable. Ntxiv nrog rau cov dej tsis zoo thiab tshuaj lom neeg ruaj khov, qhov o qhov siab thiab qhov nqus dej hauv ib lub sijhawm yog qhov tseem ceeb tshaj plaws ntawm cov dej thaiv kab xev.
5. Steel yas composite daim kab xev thiab txhuas yas puas daim kab xev
Cov hlau yas puas daim kab xev thiab txhuas yas puas daim kab xev nyob rau hauv lub optical cable yog feem ntau longitudinal wrapping armored nrog corrugated, thiab tsim ib tug zoo sheath nrog PE txheej sheath. Lub zog tev ntawm daim kab xev steel / aluminium ntawv ci thiab cov yas zaj duab xis, lub tshav kub sealing lub zog ntawm cov ntaub nplaum sib xyaw, thiab lub zog sib txuas ntawm cov ntaub nplaum sib xyaw thiab PE txheej txheej muaj kev cuam tshuam zoo rau kev ua tiav ntawm cov khoom siv kho qhov muag. Roj compatibility kuj tseem ceeb, thiab cov tsos ntawm cov hlau puas daim kab xev yuav tsum tiaj tus, huv si, tsis muaj burrs, thiab tsis muaj kev puas tsuaj rau txhua yam. Tsis tas li ntawd, txij li cov hlau yas sib xyaw daim kab xev yuav tsum tau muab qhwv ntev los ntawm qhov loj me thaum lub sijhawm tsim khoom, lub thickness uniformity thiab txhua yam muaj zog yog qhov tseem ceeb rau cov chaw tsim khoom kho qhov muag.
