Iav yarn rau optical cables
Khoom taw qhia
1. Tiv thaiv cov qauv sab hauv ntawm cov khoom siv kho qhov muag (lub iav sheath tag npog thawj lub plhaub, tiv thaiv cov qauv sab hauv los ntawm kev puas tsuaj)
2. Tiv thaiv cov squirrels los ntawm cov neeg tom ( iav gauze tuaj yeem tiv thaiv los yog txo cov squirrels los ntawm kev kho qhov muag cables). Txawm hais tias cov tawv nqaij sab nrauv raug tom los ntawm cov iav gauze tiv thaiv nas los ntawm kev tom thiab muab kev tiv thaiv ntxiv.
3. Txhim kho lub zog ntawm cov kab hluav taws xob (cov khoom siv muaj zog iav fiber ntau ua rau cov kab hluav taws xob tiv thaiv kab mob zoo heev, txhim kho cov kav ntev thiab lub neej ntawm cable)
4. Qhov saum npoo yog txuas nrog ib txheej ntawm mos PU nplaum zaj duab xis, zoo tensile kev ua tau zoo, tsis yooj yim rau tawg, thiab kev kho qhov muag cable tsis ua mob rau tib neeg lub cev.
Tam sim no, cov qauv ntawm cov iav fiber ntau yog 300D / 600D / 785D / 1200D, uas tau muab faib ua cov iav fiber ntau thiab cov iav dej-resistant iav fiber ntau, uas tuaj yeem xaiv raws li qhov xwm txheej tiag tiag.
