Abstract:
1. A customer premises optical network unit (ONU) comprising: an electrical/optical transform 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 ONU function part to be connected with an electric signal input and output terminal of the electrical/optical transform unit; a serial/parallel transform unit to be connected with a parallel signal terminal of the ONU function part for performing a serial/parallel transform and an inverse serial/parallel transform; and a multi source agreement (MSA) interface module to be connected with a serial signal terminal of the serial/parallel transform unit, wherein the ONU function part comprises a signal terminal configured to output a received establishment signal to an external node to be connected with the MSA interface module, triggered by a signal output when a passive optical network (PON) link with the central office side is established, or when authentication with the central office side is established.
