    摘要： A wavelength division multiplexed (WDM) optical communications network is configured and operated to enable transmitter output power for a given wavelength channel to be adjusted to achieve a desired optical signal-to-noise ratio (OSNR) for the channel independently of the power levels of other optical signals carried on the same path. Optical amplifiers in the optical links extending between the transmitter and an optical receiver are configured to operate with constant gain over a specified range of input optical signal power, and the links are configured such that the power level of the signal provided to each optical amplifier is within the specified range of input signal power to prevent the deep saturation of the optical amplifiers due to optical amplifier cascading. When a channel is being added or adjusted, the OSNR of the optical communications signal received by the receiver is measured, and the power of the signal transmitted by the transmitter is adjusted to attain a desired OSNR at the receiver. Due to the constant-gain operation and input power control of the optical amplifiers, the OSNRs of other signals carried on the path are not affected, so that it is unnecessary to adjust the output power of other transmitters providing signals to the path.

    摘要： The frequency chirp modulation response of a directly modulated laser is described using a small signal model that depends on slow chirp amplitude s and slow chirp time constant τs. The small signal model can be used to derive an inverse response for designing slow chirp compensation means. Slow chirp compensation means include electrical compensation, optical compensation, or both. Slow chirp electrical compensation can be implemented with an LR filter or other RF circuit coupled to a direct modulation source (e.g., a laser driver) and the directly modulated laser. Slow chirp optical compensation can be implemented with an optical spectrum reshaper having a rounded top and relatively large slope (e.g., 1.5-3 dB/GHz). The inverse response can be designed to under-compensate, to produce a flat response, or to over-compensate.

    摘要： A high speed DWDM optical transmission system that reduces a fiber dispersion limit without reducing the total channel count of a multi-wavelength optical signal. The system achieves such reduction in the fiber dispersion limit by employing a multi-wavelength optical signal comprising a gap-free band structure, and performing per-band dispersion compensation on the optical signal by adjusting residual dispersion values associated with one or more of the bands. In one embodiment, the system includes a first dispersion compensation module (DCM) that provides a dispersion-compensated multi-wavelength optical signal containing wavelength-dependent residual dispersion to a band splitter. The band splitter separates the dispersion-compensated optical signal into a plurality of bands such that no band gaps are formed between adjacent bands, and provides each band to a respective second DCM configured to reduce the residual dispersion associated with that band to a predetermined range of residual dispersion values.
