Abstract:
1. An optical interconnection module for multiplexing first and second NRZ input signals synchronous by a clock signal, comprising: a first converting circuit configured to convert the first NRZ input signal to a first modulation signal corresponding to a first logical product between the first NRZ input signal and the clock signal; a second converting circuit configured to convert the second NRZ input signal to a second modulation signal corresponding to a second logical product between the second NRZ input signal and an inversion clock signal obtained by inverting the clock signal; an optical unit having an optical channel and configured to convert the first and second modulation signals to first and second optical signals, the first and second optical signals being guided into the optical channel and being multiplexed in the optical channel; a third converting circuit configured to convert the multiplexed optical signal from the optical channel into a multiplexed electric signal; a first producing circuit configured to produce a first logical product signal between the inputted multiplexed electric signal and the clock signal and; a second producing circuit configured to produce a second logical product signal between the multiplexed electric signal and an inverted clock signal obtained by inverting the clock signal; and an output circuit configured to convert the first logical product signal and second logical product signal to first and second digital output signals corresponding to the first and second NRZ input signals and output first and second digital output signals, respectively.
