摘要： An optical hub node apparatus can be configured to include N+1 or more route units (10) by connecting N or less route units (10) selected from among the N+1 or more route units (10) to a route unit (10) including N (N:integer of 2 or more) ports to which other route units (10) are detachably connected. As a result, as compared with a case where N+1 route units (10) are completely interconnected in a meshed manner, the number of the route units (10) can be increased. Thus, the number (degree) of optical transmission apparatuses connectable to the optical hub node apparatus can be increased.
