GDFKJH, Tight buffered fibers yog nyob ib puag ncig nrog lub helical steel hose thiab ib txheej ntawm aramid yarns raws li tus tswv cuab lub zog, thiab ces ib tug LSZH sheath yog extruded los tsim ib tug optical sub-unit. Optical sub-units thiab tooj liab xov hlau yog stranded nyob ib ncig ntawm ib tug non-metallic central lub zog tswv cuab los tsim ib tug cable core. Lub hauv paus yog qhwv nrog dej thaiv daim kab xev. Thaum kawg, LSZH txheej txheej yog extruded. Lwm cov ntaub ntawv sheath muaj nyob rau ntawm kev thov.
