ABSTRACT:
In an optical multiplexing interconnection module, first and second NRZ input signals synchronous by clock signal are inputted to its input section. The first NRZ input signal is converted to a first RZ signal according to a logical product with a clock signal CLK by a drive circuit and the second NRZ input signal is converted to a second RZ signal according to a logical product with an inversion clock signal by a drive circuit. Then, light emitting devices are driven according to the first and second RZ signals from these drive circuits and two optical signals from the light emitting devices are inputted to an optical channel and multiplexed therein and then, a multiplexed optical signal is transmitted through an optical channel.
