Analysis of transmission of sub-carrier multiplexed signals through the optical transport network

The transmission of analog SCM signals through the optical layer of the tra nsport network is analyzed and discussed, in order to assess the possibilit y of exploiting the core network for the transport of video channels, witho ut the need of dedicated communication systems. The utilized analytical mod el, allowing the transmission performance to be evaluated, is reported. Som e performance evaluation results are reported, taking into consideration tw o relevant network typologies: metropolitan networks and regional networks. The results allow the feasibility of the considered approach to be assesse d, considering the available technology.
