    摘要: Techniques are described for identifying a rogue network interface device whose laser is not under control of a controller of the network interface device. The techniques identify the rogue network interface device based on reception of a predefined data pattern in a timeslot that is not reserved for any of the network interface devices without needing to disable upstream data transmission from the network interface devices during their assigned timeslots. The techniques also relate to a network interface device determining whether the network interface device is transmitting optical signals at a wavelength different than the wavelength that the OLT to which the network interface device is associated receives.

The receiving apparatus 20 includes amplifying units 102 and 113 that amplify each burst signal; a detecting unit 116 that detects arrival of the burst signal from an output signal from the amplifying units 102 and 113; a comparing unit 104 that compares the output signal from the amplifying units 102 and 113 with a predetermined threshold value and outputs a binary signal; and a control unit 108 that sets the timings of changing a receive function during the synchronization section by adding delay times Dai and Dbi to a detection time point where the detecting unit 116 performs an output. The control unit 108 is configured to be able to change the delay times Dai and Dbi in a plurality of ways.

    摘要: A first phase setting circuit generates a first phase setting signal. A first synchronous signal generator generates a first synchronous clock signal having a phase set by the first phase setting signal from a multi-phase local clock signal. By removing a phase fluctuation component representing phase fluctuation of the reception data signal from a first signal including a frequency component representing a frequency offset between a multi-phase local clock signal and a reception data signal and the phase fluctuation component, a second generation unit generates a second signal including the frequency component. The first phase setting circuit updates the first phase setting signal according to the second signal.
