Low smoke zero halogen or low smoke halogen free (LSZH) is a typical cable jacketing material classification which composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat. LSZH fiber optic cable jacket is more fire-resistant compared with common PVC jacketed cables. With LSZH compound, Low smoke zero halogen cable reduces the amount of toxic and corrosive gas emitted when superheated, meanwhile the material burns to ash so it eliminates the risks in the event of a fire in the industrial environment. Low smoke halogen free cable may be run through risers directly to a convenient network or splicing closet for interconnection. Fiber-Mart supplies high quality single mode & multimode, double & single jacket, gel-filled, strength membered, FTTH, indoor/outdoor fiber optic low smoke & zero halogen LSZH cables.
