The physical link between the CPE and central office parts of the network is based on a point-to-point (PtP) architecture. Within this architecture, the fiber-to-the-home (FttH) network enables the transport of two basic service types: communication through an Ethernet/IP network, and broadcast of (video) content through a CATV network overlay.
In the OPTISIS FttH network with RF overlay, each user is connected to a CATV distribution system. Therefore, in the simplest solution each user is connected to the central office with a single cable containing a fiber pair: one fiber for bidirectional voice and data and one fiber for the CATV overlay. Solutions that multiplex all signals (Ethernet/IP and CATV) on a single fiber can also be provided (single fiber solution).
The figure below provides a schematic overview of the Genexis CATV network overlay.
Four basic elements are of relevance:
The network management system GAPS also offers control of the CATV network. Specifically, the optical CATV receiver can be enabled and disabled remotely via the management system.
