(under subclass 109) Subject matter wherein the system as a whole, not just a single piece of the system, is evaluated prior to the communication use.
(1) Note. The overall combination of an optical communication system having, for example, an optical link between a transceiver and a repeater is classified in this class.
(2) Note. If the transceiver, while operating in the total optical communication system as classified in this class, is being tested by a device using optical signals, the claimed subject matter is classified in this subclass.
