LSZH stands for Low Smoke Zero Halogen. The inner structure and parameters of a LSZH cable are similar to other types of fiber optic cables, such as PVC. What makes the LSZH cable stand apart from other cables is its jackets. The LSZH fiber optic jacket is more fire-resistant than PVC jacketed cables. Should they catch on fire, the burning LSZH cables give off low smoke and no halogen substances, which is important not only for the environment but also for the people and facilities nearby the cables. Therefore, LSZH fiber optic cables are widely used in crowded areas like high-rise buildings, commercial centers, sports centers, airports, and libraries.
