A Network Architecture for Providing Legacy Network Services and Next-Generation Access Network Services Having a Self-Restoring Function and A Method for Configuring Optical Path Therein

摘要

The present invention includes a self-recovery for the network to provide next generation network services existing network services . discloses a method and a network structure constituting the structure ; a passive optical network (PON) architecture according to the present invention, central office (CO); The CO and the remote node is connected (RN); Including the RN and the plurality of subscriber is connected, and the CO and the RN are connected to the first and second feeder fiber (FF-1 and FF-2), the CO, for providing a conventional PON service 1 optical termination equipment (legacy PON OLT); Second optical termination equipment for providing services NG-PON (WDM-PON OLT); And the first switching block is provided for a connection with at least one of the existing PON service and the NG-PON service to at least one of the first and second feeder fiber (FF-1 and FF-2) (SB-1) includes a, RN is the first and second multiplexer / demultiplexer (MUX / DEMUX); And the existing PON service and the first at least one of the NG-PON service and a second multiplexer / demultiplexer (MUX / DEMUX) a second switching block (SB-2) provided to be connected to at least one of the provided, it said passive optical network structure is constantly in is characterized in that for resetting the temporarily while the optical path of the non-PON operates in power characteristics.
