Abstract
An optical hub node apparatus can be configured to include N+1 or more route units () by connecting N or less route units () selected from among the N+1 or more route units () to a route unit () including N (N:integer of 2 or more) ports to which other route units () are detachably connected. As a result, as compared with a case where N+1 route units () are completely interconnected in a meshed manner, the number of the route units () can be increased. Thus, the number (degree) of optical transmission apparatuses connectable to the optical hub node apparatus can be increased.
