Communication/ Broadcasting Converging FTTH System Using Passive Optical Network or Aactive Optical Network

摘要

The present invention relates to a broadcast communication convergence system, and more particularly to FTTH (Fiber To The Home).;The PON broadcast / communication convergence FTTH system according to the present invention is a PON (Passive Optical Network) broadcast / communication convergence FTTH (Fiber To The Home) system. Receives one optical signal λ1 including a communication signal and separates the plurality of broadcast and communication signals by photoelectric conversion, and converts the converted plurality of broadcast and communication signals for each subscriber. PON Optical Network Unit (ONU) for transmitting to [lambda] 11; An L2 switch for receiving the optical signal [lambda] 11 and delivering the broadcast and communication signal to each subscriber-specific device; And a voice over IP (VoIP) gateway that receives the optical signal λ 11 and transmits a signal corresponding to an Internet telephony signal among the broadcast and communication signals to each subscriber-specific device. The PON ONU and L2 switches Alternatively, at least one of the VoIP gateways may be configured to receive power from a coaxial cable of a hybrid fiber coaxial (HFC) network.;PON, AON, ONU, L2 Switch, L2 Aggregation Switch, VoIP Gateway
