Optical fiber applications in interiors have their own peculiarities and requirements. The Fibercom generator for interiors has been developed specifically to meet these requirements. It is a very quiet and compact generator that can be placed anywhere in an interior even if the space is small. In electronic terms it consists of a special long-lasting lamp, and control electronics that enable its turning on and off, choice of projection colour and selection of functioning modes. All indoor generators can be synchronised with outdoor generators.
