摘要：An optical switching system receives an optical input signal which is a

wavelength-division multiplexed and time-division multiplexed signal. The optical inputsignal is divided into time-division multiplexed optical signals in different wavelengthregions and transferred within an optical data bus (800) after being subjected to a

predetermined process including a frequency shift. The optical signals in the differentwavelength regions are extracted from the optical data bus (800) using optical bandpassfilters, and multiplexed into an output optical signal which is a wavelength-divisionmultiplexed and time-division multiplexed signal after being subjected to apredetermined process including a frequency shift.
