GDFJAH - Tight buffered fibers nyob ib puag ncig nrog ib txheej ntawm aramid yarns ua tus tswv cuab lub zog. Lub LSZH puab sheath yog extruded rau ntawm lub nruj buffered fiber ntau los tsim ib tug optical sub-unit. Tom qab ntawd optical sub-units thiab tooj liab xov hlau yog tso tseg nyob ib ncig ntawm ib tug uas tsis yog-metallic central zog tswv cuab los tsim ib tug cable core. Cov tub ntxhais yog armored nrog laminated aluminium daim kab xev. Thaum kawg, LSZH txheej txheej yog extruded. Lwm cov ntaub ntawv sheath muaj nyob rau ntawm kev thov.
