<P>PROBLEM TO BE SOLVED: To facilitate formation of a static optical network which connects each of a plurality of nodes with the other node independently on one-to-one correspondence, and to minimize an increase in number of optical terminals in a hub even if the number of nodes increases. <P>SOLUTION: Two nodes selected arbitrarily in pairs from nodes N1-N6 to constitute a set are connected in common with any one of hubs Hub-1 through Hub-3. The node N1 is connected on one-to-one correspondence with the nodes N2, N3 and N4 through the Hub-1, and connected on one-to-one correspondence with the node N5 and N6 through the Hub-3. Similarly, the nodes N2-N6 are connected independently on one-to-one correspondence with the other nodes through any one of the Hub-1 through Hub-3. <P>COPYRIGHT: (C)2010,JPO&INPIT |
