摘要： An amplitude encoded transmission system and method are disclosed that achieve an improved bit-error rate for systems with a non-linear input/output relationship in the presence of noise. A set of measures are determined for adjacent signal levels. The set of measures are compared to each other. When at least one of the set of respective measures does not approximate the remaining measures in the set of measures, one or more signal levels are adjusted until the set of respective measures of the transmitter approximate each other. The method can be applied during a select manufacturing stage of the transmitter. An integrated system includes an optical emitter, modulator, photosensitive diode and signal-level adjuster. The modulator receives a set of control signals to operate the emitter at a desired output level. The photosensitive diode generates a feedback signal that is used by the signal-level adjuster to generate a bias signal.

摘要： Spectrum control systems and methods are implemented to minimize power spectral density (PSD) offsets by adjusting gain of optical amplifiers in an optical section. The optical section is a logical boundary from one optical signal access point to a next adjacent optical signal access point. The systems and methods include estimating PSD offset from a given target for a peak channel at each span in the optical section, wherein the estimated PSD offset is divided at each span into two components including a self-introduced offset and an uncompensated offset from upstream; generating, for each span, a separate controller response for the self-introduced offset and the uncompensated offset from upstream; and controlling the gain of the optical amplifiers based on the separate controller response for the self-introduced offset and the uncompensated offset from upstream, for each span.

摘要： A system and method that enforces one or more policy rules on user-allocated bandwidth portions of the overall system bandwidth, for example in an optical fiber transmission system. The policy rules may limit, for example, the range of optical wavelengths, the acceptable range on the output-power-spectral density and/or the total per-band optical power within the user-allocated bandwidth that a user may provide on the system. The system may include one or more user control units that receives respective user output signals and applies all policy rules. The resulting optical output(s) of the UCU(s) may be provided an optical transmission path for transmission to a receiving terminal. In the receiving terminal, one or more UCU(s) may apply receiver policy rules, for instance by limiting the range of wavelengths transmitted to a receive subsystem. In addition, the system may be configured to dynamically add and/or remove loading signals to the transmitted signal in response to changes in loading of the user-allocated portions of the system bandwidth, e.g. through dropping or adding of channels by a user or by equipment failures.
