FTTH Cable Sab Hauv Tsev
FTTH poob cable nrog kev nkag tau yooj yim rau cov fiber thiab kev teeb tsa yooj yim, FTTH cable tuaj yeem txuas ncaj qha rau cov tsev.
Nws yog qhov tsim nyog rau kev txuas nrog cov khoom siv sib txuas lus, thiab siv ua txoj hlua nkag mus rau hauv tsev hauv qhov system faib khoom. Cov fiber ntau optical tau muab tso rau hauv nruab nrab thiab ob lub zog Fiber Reinforce Plastic (FRP) sib luag tau muab tso rau ntawm ob sab. Thaum kawg, lub cable tau ua tiav nrog LSZH sheath.
Nta: 1. Mos thiab khoov tau, yooj yim rau kev xa tawm thiab kev saib xyuas. 2. Me dua txoj kab uas hla, Lub teeb yuag, thiab siab ua tau. 3. Cov yas fiber reinforced ua lub zog ntawm cov tswv cuab ua kom muaj kev ua tau zoo heev ntawm electromagnetic. 4. Kev tiv thaiv ib puag ncig - Haus luam yeeb tsawg, xoom halogen thiab nplaim taws retardant sheath. 5. Kev ua tau zoo ntawm cov dej tsis muaj zog.
Cov yam ntxwv ntawm fiber ntau: Cov Kev Cai Cable: Cov yam ntxwv ntawm txhua yam khoom siv thiab ib puag ncig:
