摘要： An optical signal generation unit (110) generates an optical signal for transmission by adding modulation based on a driving signal to a carrier wave. A filtering unit (120) performs a filtering process on the driving signal. The filtering unit (120) may perform time domain equalization, and may perform frequency domain equalization. Specifically, the filtering unit (120) performs a filtering process on the driving signal, and thus sets a peak value of a power spectral density of the optical signal for transmission to be equal to or less than a second reference value while an integrated value obtained by integrating the power spectral density of the optical signal for transmission in a frequency direction is maintained at equal to or greater than a first reference value.

摘要： An optical transmitting apparatus includes semiconductor laser elements. Upon receiving laser beams, a multiplexed beam is emitted from a wavelength multiplexing filter. The wavelength multiplexing filter includes a triangular prism and a wavelength multiplexing filter film. A front end face and a rear end face of the prism are not parallel to each other so that a prism angle at which a surface parallel to the front end face intersects a surface parallel to the rear end face, is an acute angle. The prism angle is the angle at which the laser beam impinging from the front end face into the triangular prism is reflected by the wavelength multiplexing filter film toward the front end face and the multiplexed beam is directed to the optical axis side of the optical fiber.

摘要： Methods, systems, and devices are described for modulating and demodulating data on optical signals. During modulation, at least one stream of symbol mapped bits is filtered with at least one pulse shaping filter to reduce a bandwidth of the stream of bits and to pre-compensate for at least one identified non-ideal transmission condition. The filtered bits are modulated onto a waveform in the digital domain, and the modulated filtered bits are transmitted to digital-to-analog converter. The output of the digital-to-analog converter is converted to an optical signal. During demodulation, a received optical signal is sampled at a first sampling rate at an ADC, downsampled to a lower sampling rate for filtering, filtered with at least one discrete pulse-shaping filter, upsampled for equalization and demodulation, and then equalized and demodulated.
