Welding of fiber ducts

Save favourite 12 Jan January 2017

The objective of this activity is to streamline the fiber installation and maintenance by developing a new method for splicing fiber ducts with welding. Joining fiber ducts is done in difficult environments and involves large workload.

Optical fibers are installed by blowing the fiber into already buried tubes, called ducts. Today fiber ducts are joint together with a technology based on the same principle as for compressed air hoses and are not designed for buried fiber installations. To improve the technology, a product based on welding will be developed and evaluated within the project. The new product will give better mechanical properties, smaller workload, higher reliability and shorten the joint time for the installer. The new product will be tested and evaluated together project partners to get fast feedback on how the solution affects the workload and efficiency of the installation work. It will develop a new generation of joints and equipment to weld them by remelting of the surface layer. Different types of joints will be evaluated.
