Cov kev cai yooj yim rau kev tsim thiab tsim cov txheej txheem ntawm optical fiber thiab cable

Qhov yuav tsum tau muaj rau kev tsim cov txheej txheem ntawm optical cables yog yooj yim thiab txhim khu kev qha. Raws li cov yam ntxwv ntawm optical cables, cov ntsiab lus hauv qab no yuav tsum ua tiav:
1. nruj me ntsis tswj cov nyhuv ntawm qhov nro ntawm cov khoom siv kho qhov muag thaum lub sij hawm them nyiaj thiab nqa tawm, kom ntseeg tau tias cov khoom siv kho qhov muag tsis tu ncua uas tsis tshua muaj kev ntxhov siab thiab kev ntxhov siab;
2. nruj me ntsis tswj lub microbending attenuation tshwm sim los ntawm cov neeg kho tshuab sab nraud quab yuam thaum lub sij hawm tsim khoom, thiaj li hais tias nws tsis cuam tshuam rau kev sib kis ntawm fiber ntau optical;
3. Xaiv cov txheej txheem yas extrusion tsim nyog kom tsis txhob muaj microbending attenuation los ntawm cov yas thermal shrinkage vim kev ua tsis raug, thiab xyuas kom lub sij hawm ntev ruaj khov kev ua tau zoo ntawm cov optical cable.
4. Cov txheej txheej ntawm cov kab hluav taws xob kho qhov muag yog siv los txhim kho lawv cov kev tiv thaiv sab nraud, lub zog tensile, thiab cov ntaub ntawv pov thawj ya raws. Tam sim no, muaj yim yam tseem ceeb ntawm cov txheej txheem txheej txheej rau optical cables hauv Suav teb:
(1) Yooj yim polyethylene sheath (PE sheath) qauv;
(2) Aluminium / polyethylene composite longitudinal bonding tiv thaiv txheej (LAP) qauv;
(3) Corrugated steel sawb nrog longitudinal sib tshooj thiab PE tiv thaiv txheej txheej;
(4) Aluminium / polyethylene composite longitudinal bonding tiv thaiv txheej nrog corrugated steel sawb sib tshooj thiab PE tiv thaiv txheej sib tshooj;
(5) Aluminium / polyethylene composite longitudinal bonding tiv thaiv txheej nrog steel strip longitudinal bonding thiab PE tiv thaiv txheej overlapping;
(6) Txhuas / polyethylene composite longitudinal bonding tiv thaiv txheej nrog corrugated steel strip longitudinal bonding thiab PE tiv thaiv txheej overlapping;
(7) Txhuas / polyethylene composite longitudinal bonding tiv thaiv txheej, steel hlau armor, thiab PE tiv thaiv txheej sib tshooj;
(8) Aluminium raj / armor / PE tiv thaiv txheej txheej txheej txheej txheej.
