Abstract

The present invention relates to an optical network system between optical line terminals in a time division passive optical network. The present invention comprises forming an optical network between optical line terminals (OLT), one of which exists in each optical network of multiple members comprised of a time division passive optical network, based on wavelength division multiplexing. According to the invention, more economic and efficient optical network conditions are provided between optical line terminals in a time division passive optical network.
