What's the Difference between PVC and LSZH Cable?
As we know, much of the cable currently in use in the United States and elsewhere in the world contains halogens. The European market is demanding that cables used in LANs, WANs, etc. Meet LSZH specification. The IEC 60332-1 governs the Flame Retardant Grade specifications in reference to LSZH cable.
Essentially the compound used in manufacturing cables meeting the above specifications reduces the amount of dangerous/poisonous gases in case of fire. The main difference in specifications between IEC 60332-1 versus UL 5181, UL 1666 and UL 910 is that the cable under the IEC specifications continues to burn while still emitting very low gases. The UL specs demand that the flame be extinguished, but it can still be emit poisonous/dangerous gases.
A PVC cable is made of polyvinyl chloride. It has a jacked that gives off heavy smoke, hydrochloric acid, and other toxic gases when it burns. Low smoke zero halogen cable has a flame-resistant jacket that doesn’t emit toxic fumes even if it burns. PVC patch cords are soft, while LSZH patch cords are more rigid because they contain the flame retardant compound, and they are aesthetically more pleasing.
Many different fibre optic cable manufacturers are now making low-smoke, zero-halogen (LSZH or LS0H) cables.
These cables are designed to emit no toxic fumes and produce little or no smoke when exposed to flames. Tunnels, enclosed rooms, aircraft, and other minimum-ventilation areas are prime spots for the use of LSZH cables because those areas are more difficult to escape from quickly.
