Embedding optical fibers into composite material is becoming a common procedure in various applications. Telecommunication optical fibers are commercially provided with acrylate or polyimide coating which are suitable when embedded into those materials. The situation is completely different when one think to embed optical fibers into metallic or ceramic materials or more in general when the application is at very high temperature. In this paper we use the electrowinning technique to deposit a sufficiently high thickness of a metallic protecting coating on optical fibers to be embedded into metallic and ceramic materials. A cylindrical cell has been used to electrodepose a uniform thickness of metal on optical fibers after making it conductive by a thin layer of graphite or aluminum. Metals having high melting temperature have been used to prepare the electrolyte. Different operative conditions such as current density, temperature, solution pH have been tested to optimize both process and protective coating properties.
