摘要： An optical network comprises a plurality of optical network units and an optical line terminal having one or more transmitters and one or more receivers. Each of the one or more transmitters and each of the one or more receivers is configured to operate over a respective wavelength.

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.
