Abstract
Official abstract text for this publication.
An optical network interconnect device interconnects a first WDM network for transmitting a WDM optical signal with first wavelength spacing and a second WDM network for transmitting a WDM optical signal with second wavelength spacing that is wider than the first wavelength spacing. The optical network interconnect device includes a filter to remove a wavelength component which is not used in the second WDM network from an WDM optical signal transferred from the first WDM network to the second WDM network.
First claim
Opening claim text (preview).
What is claimed is: 1. An optical network interconnect device that interconnects a first WDM network for transmitting a WDM optical signal with first wavelength spacing and a second WDM network for transmitting a WDM optical signal with second wavelength spacing that is wider than the first wavelength spacing, the optical network interconnect device comprising: an optical branch device configured to branch the WDM optical signal of the first WDM network; and an optical filter co…
