A silica core tube, also known as HDPE silica core duct, is a professional composite plastic pipe specially used for optical fiber and cable protection. Different from ordinary HDPE pipes, it features a permanent silica lubricating inner layer, which greatly reduces friction for fiber blowing and pulling. It is the most popular pipe for 5G communication, highway, railway and underground cabling projects worldwide.
