2.Optical Fiber In Cable (ITU-G.652D)

Optical properties of the SM fiber are achieved through a germanium doped silica based core with a pure silica cladding which meets ITU-T G.652D, UV curable acrylate protective coating is applied over the glass cladding to provide the necessary maximum fiber lifetime.
