    • [Problem] To provide an optical network unit (ONU) for P-P that can discriminate the type of a downstream signal corresponding to the construction of an optical access network and control an enable state of an optical transmitter Tx. [Solving Means] ONU 2A for P-P according to the present invention includes a bidirectional optical transceiver 11 that bidirectionally communicates with an optical line terminal (OLT), a signal-type discriminating unit 22A that discriminates whether a type of a downstream signal transmitted from the OLT and received by the bidirectional optical transceiver is for the P-P or not, and outputs an enable/disable control signal that controls an optical transmitter of the bidirectional optical transceiver to an enable state or a disable state in accordance with a discrimination result of the type of the downstream signal, and a control unit 21 that controls the optical transmitter to the enable state or the disable state according to the enable/disable control signal, wherein the signal-type discriminating unit 22A outputs to the control unit 21 a disable control signal that controls the optical transmitter to the disable state under an initial state before the type of the downstream signal is discriminated, and outputs to the control unit 21 an enable control signal that controls the optical transmitter to the enable state after the downstream signal is discriminated to be for the P-P.
    • [问题]提供一种用于P-P的光网络单元(ONU),其可以区分对应于光接入网络的结构的下行信号的类型并控制光发射机Tx的使能状态。 [解决方案]根据本发明的用于PP的ONU2A包括与光线路终端(OLT)双向通信的双向光收发器11,信号类型鉴别单元22A,其判别从 OLT和由双向光收发器接收的是用于PP的PP,并且根据类型的判别结果,输出将双向光收发器的光发送器控制到使能状态或禁止状态的使能/禁止控制信号 以及根据使能/禁止控制信号将光发送机控制到使能状态或禁止状态的控制单元21,其中信号类型识别单元22A向控制单元21输出禁用控制信号 其在下游信号的类型之前的初始状态下将光发射机控制为禁用状态 并且在下行信号被鉴别为P-P之后,将控制光发送机的使能控制信号输出到控制单元21。
