Differences Between LSZH and PVC Cable Judging from the physical appearance, the difference between LSZH and PVC cable is very distinct. A PVC cable feels soft and it is smooth, whereas an LSZH cable feels rough since they contain the flame retardant compound and it is stiffer.

Is LSZH better than PVC?

A PVC cable (made of polyvinyl chloride) has a jacket that gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. Low Smoke Zero Halogen (LSZH) cable has a flame-resistant jacket that doesn’t emit toxic fumes even if it burns.

What is LSZH fiber optic cable?

LSZH fiber optic cable has no difference from other fiber optic cables, but it has a special cable jacket which is made of LSZH materials. LSZH stands for Low Smoke, Zero Halogen. This type of cable jacket has excellent fiber safety characteristics of low smoke, low toxicity and low corrosion.

Is LSZH cable flame retardant?

The cables are also commonly referred to as ZHLS cables or halogen free cables. They often have flame retardant properties, making them flame retardant low smoke (FR-LS) cables.

What is LSZH cable made of?

LSZH cable jacketing is composed of thermoplastic or thermoset compounds that emit limited smoke and no halogen when exposed to high sources of heat.


The single core cable is armoured with aluminium wires (AWA) to prevent induced current in the armour….XLPE/LSZH/AWA/LSZH BS6724 cable construction.

Is PVC halogen free?

PVC or polyvinyl chloride is not a halogen-free material because it contains chlorine.

Is LSZH Riser Rated?

LSZH with OFNR rating enables use in riser-rated environments. Halogen free design offers improved safety performance. All multimode, and singlemode cables (except OM1) utilize bend-insensitive optical fibers.

What is OFCR cable?

OFCR: OFCR stands for fiber optic conductive riser. A factory assembly of one or more optical fibers having an overall covering and containing non–current-carrying conductive members such as metallic strength member, metallic vapor barrier, metallic. armor or metallic sheath.

What is LSF material?

LSF stands for “Low Smoke and Fumes.” This type of cable is made up of PVC compound that has been modified to decrease the amount of gas and smoke that is produced when burning compared to traditional PVC designs.

Is LSF cable thermoplastic or thermosetting?

thermosetting cable
A LSF (low smoke and fume) type of thermosetting cable is available. Provided that it is kept dry, a mineral insulation such as magnesium oxide is an excellent insulator.
