An optical wavelength division multiplex (WDM) transmission system, especially a WDM passive optical network |
摘要 |
The invention relates to an optical wavelength division multiplex (WDM) transmission system, especially a WDM passive optical network, comprising a central node having a first and a second WDM port and a remote node having a first and a second WDM port and a plurality of channel ports, the central node first WDM port being connected to the remote node first WDM port via a bidirectional single-fiber optical working path and the central node second WDM port being connected to the remote node second WDM port via a single-fiber bidirectional optical protection path, and a group of basic optical node units (ONU's) each of which is connected to a respective remote node channel port via a bidirectional optical ONU path, each ONU comprising an optical receiver for receiving a downstream optical channel signal and an optical tunable transmitter for creating an upstream channel signal. |
