(under subclass 118) Subject matter wherein an optical data distribution system, containing a common node connected to one end of each of three or more branches and the other end of the branches are connected to each member of a local area network multiplex system, permits optical information flow between all of the members; and each member receives its power (i.e., active) from the received optical signals.
(1) Note. A collision detection device in a star has its own power supply yet the incoming optical signals are not converted to electrical energy and this subject matter would be classified in this subclass.
(2) Note. Incoming optical signals which become the source of power within the star for all terminals as a result of conversion into electrical signals would be classified in this subclass.

121, for passive star local area networks (LAN's).
