| 摘要 |
The device has wavelength selective switches (126) each comprising inputs to receive wavelength channels. Spatial optical switching matrixes (40, 43) with optical links (41, 42) connect transit outputs of a diffusion coupler (125) to transit inputs of the switches to transit an incoming wavelength-multiplexed optical signal towards the switches. The switches are arranged in groups of optical fibers (117-119). One of the groups has switches each being connected to a common contiguous node at output. The matrixes and links are arranged to broadcast the signal towards a switch of the group. |
