An LSZH jacket means only the outer sheath is made from a low smoke, zero halogen compound. In contrast, an LSZH cable specifies that all applicable material layers throughout the cable’s construction use LSZH compounds, including internal insulation and structural components, not solely the outer jacket. The Kordz R.4 48Gbps Rack and Marine Passive HDMI Cable is built as a complete LSZH cable, ensuring its entire construction meets IEC60332, IEC60754 and IEC61034 requirements for fire safety and suitability in marine and other compliance-driven environments.
