With advances in technology in modern day Telecommunications, over a period of time, it became very important to upgrade the HDPE pipes to be used particularly for Telecom applications. The Optical Fibre Cables used for Telecommunications being very delicate and sensitive, it became necessary to modify the HDPE Pipes to be used as conduits for optical fibre cables. This led to the development of Permanently Lubricated (PLB) HDPE Telecom Ducts.
The inner layer of ducts is duly silicon coated which minimizes the friction between OFC and the duct during the process of blowing the cable into the ducts, thus providing smooth installation of OFC in the duct without damaging the cable fibres.
