摘要： In some embodiments, an apparatus includes an optical detector that can sample asynchronously an optical signal from an optical component that can be either an optical transmitter or an optical receiver. In such embodiments, the apparatus also includes a processor operatively coupled to the optical detector, where the processor can calculate a metric value of the optical signal without an extinction ratio of the optical signal being measured. The metric value is proportional to the extinction ratio of the optical signal. In such embodiments, the processor can define an error signal based on the metric value of the optical signal and the processor can send the error signal to the optical transmitter such that the optical transmitter modifies an output optical signal.

摘要： Using pump-probe measurements on multi-span (10) optical links (8) may result in the determination of one or more of the following: 1) wavelength-dependent power profile and gain evolution along the optical link; 2) wavelength-dependent dispersion map; and 3) location of regions of high polarization-dependent loss 'PDL' and polarization-mode dispersion 'PMD'. Such measurements may be a useful diagnostic for maintenance and upgrade activities on deployed cables as well as for commissioning new cables.

摘要： The disclosure provides a method and device for detecting rogue behaviour. The method comprises: for the upstream optical signal of each Passive Optical Network (PON) port, an Optical Line Terminal (OLT) constructs a short timeslot and transmits it via an optical transceiver; the OLT controls the optical transceiver to conduct a first Signal Detect (SD) sampling detection on the upstream optical signal according to the short timeslot to obtain a first detection result; the OLT judges, according to the first detection result, whether the upstream optical signal is valid; if so, the OLT constructs a long timeslot and transmits it via the optical transceiver, and controls the optical transceiver to conduct a second SD sampling detection on the upstream optical signal according to the long timeslot to obtain a second detection result; and the OLT determines, according to the second detection result, whether the current PON port is experiencing rogue behaviour. The disclosure achieves quick and accurate detection without occupying fixed bandwidth, thus maximizing the utilization of the upstream bandwidth.

摘要： An automated method of characterizing distortion detected by equalization on a channel of a network is provided. Equalization stress of an observed channel equalization response of an end device of the network is estimated, and equalization stress is calculated for a theoretical channel equalization response of the end device mathematically based on the observed channel equalization response and a theoretical removal of a suspected impairment from the network. The above referenced calculating step is separately repeated for each of a plurality of suspected impairments stored in a database of suspected impairments. A highest ranking suspected dominant impairment is determined from the database of suspected impairments such that removal of the highest ranking suspected dominant impairment from the network would provide a greatest reduction of equalization stress of a channel equalization response of the end device.

摘要： Embodiments describe transceiver architectures to enable 'loopback' operation, thereby allowing or on-chip or intra module characterization of the transceiver. This includes but is not limited to tests such as bit error rate (BER) characterization, received power characterization and calibration of filters (MUX, DMUX etc.) present in the transceiver. Embodiments may also describe architectures for superimposing low-speed data on to the signal coming out of a transmitter, which in turn enables low frequency communication between network elements in the external link.
