Abstract:
1. A customer premises optical network unit comprising: an optical transceiver unit to be connected with an optical transmission path at a central office side for performing an opto-electrical transform and an inverse opto-electrical transform; an optical network unit function part to be connected with an electric signal input and output terminal of the optical transceiver unit comprising at least a communication logic unit for passive optical network (PON) processing; a serial/parallel transform unit to be connected with a parallel signal terminal of the optical network unit function part for performing a serial/parallel transform and an inverse serial/parallel transform; a multi source agreement interface module to be connected with a serial signal terminal of the serial/parallel transform unit; and two or more sheets of substrate modules, respectively, comprising a connector for connection between the sheets of substrate modules, wherein the two or more sheets of substrate modules are placed to overlap one another and connected electrically with the connector for connection between the sheets of substrate modules to each other, and wherein the optical transceiver unit, the communication logic unit for PON processing, the serial/parallel transform unit, and the multi source agreement interface module are mounted on any one of the two or more sheets of substrate modules.
