According to one general aspect, an interconnection node may be configured to dynamically provide interconnection access between a first optical network (e.g., a core optical network) and at least either a second optical network (e.g., an access optical network) or a third optical network (e.g., another access optical network) in a purely optical fashion. The interconnection node may include a first network portion and a second and third network portions. The first network portion may be coupled with the first network that includes a first pair of wavelength cross-connect (WXC) units coupled between a first transmission path of the first network, and providing a plurality of add and drop ports, and a second pair of wavelength cross-connect (WXC) units coupled between a second transmission path of the first network, and providing a plurality of add and drop ports. The second network portion may be coupled with the second network and the first network portion of the interconnection node such that optical signals may be routed between the second network and the first network. The third network portion may be coupled with the third network and the first network portion of the interconnection node such that optical signals may be routed between the third network and the first network. |
