摘要： According to one general aspect, an interconnection node is configured to dynamically provide interconnection access between a first optical network (core optical network) and a second and/or third optical network (access optical network). The interconnection node may include a first network portion and a second and/or third network portions. The first network portion may be coupled with the first network that includes a first pair of wavelength cross-connect 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 units coupled between a second transmission path of the first network, and providing a plurality of add and drop ports. The second and third network portions may be coupled with the first network portion of the interconnection node such that optical signals may be routed between the second and/or third network and the first network.
