Home / What are the types of sheaths in optical cables

The outer sheath of the optical fiber cable is divided into different material types. Keep ambient or stray light from creating signal noise (for sensor applications). This article explains the differences between LSZH, HDPE, and LDPE cable sheaths, and how to select the right option based on real deployment conditions. Whether you are designing and manufacturing a new cable or simply choosing an existing one for data, power, fiber optics, or industrial automation, the outer sheath (jacket) is much more than just a speaking cover to the eye; it is, in fact, an important job holder in mechanical protection.
