The low-smoke, zero-halogen (LSZH) materials for optical cables are primarily based on flame-retardant polyolefins and are suitable for producing the outer sheaths of various types of flexible optical cables. They comply with international standards such as IEC 60332-1 and IEC 60754, and pass the vertical flame spread test for single cables.
