Abstract: A wavelength selective light cross connect device 1A is configured of a route selector 10A including route selection elements 11-1 to 11-N, wavelength selector 20A, route selector 40A including route selection elements 41-1 to 41-M and controller 50A. The route selection elements 11-1 to 11-N select routes for WDM signals of N channels inputted to input routes Rin1 to RinN, and directs the WDM signals to the wavelength selector 20A. The wavelength selector 20A performs a selection operation to (N×M) WDM signals according to their wavelength, and outputs the signals. Wavelength selection elements 40-1 to 40-M receives different outputs obtained from the respective route selection elements via the wavelength selector 20A, selects routes and outputs the signals from output routes Rout1 to RoutM.

Abstract: A downlink signal and WDM-PON signal from an OLT 1 are separated by an optical filter part 11, and a downlink signal is split by a power splitter part 12. A WDM-PON signal is also split in each wavelength by a demultiplexer part 13, and a downlink signal and a WDM-PON signal of either one of the wavelengths are outputted to each ONU, in an optical filter part 14. Moreover, an uplink signal from the ONU is introduced to the power splitter part 12 via the optical filter part 14, and outputted to the OLT 1 via the optical filter part 11. Therefore, it is possible to realize a hybrid splitter module which allows upgrading a downlink signal to a WDM-PON without adding changes to a device on a subscriber side.
