The assignment was executed for one of the telephone, TV and Internet operator.  During the implementation a Passive Optical Network was designed and built. It uses passive devices to divide the signal to individual subscribers. The fiber optic type used in the PON enables to transmit data over long distances without losing or distorting the signal. The project was implemented in the area of  Siechnice, Olawa and Katy Wroclawskie. Thanks to the network over 7600 of flats gained access to wider range of  TV, telephone and Internet services.
