PLB Duct pipes are an important component of modern telecom and fiber optic infrastructure. The full form of PLB is Permanent Lubricated Duct, which refers to a special HDPE duct with a permanently lubricated inner surface.
This lubrication reduces friction and allows optical fiber cables to be installed through cable blowing technology quickly and efficiently. Because of this feature, PLB ducts significantly reduce installation time and labor requirements in telecom projects.
PLB ducts are widely used in optical fiber cable networks, broadband infrastructure, CATV systems, and national highway communication networks. Their durability, weather resistance, and smooth inner surface make them ideal for underground cable protection.
