192-Gbaud Signal Generation Using Ultra-Broadband Optical Frontend Module Integrated with Bandwidth Multiplexing Function

Abstract

We propose ultra-broadband optical frontend module consisting of an IQ-modulator, driver ICs, and bandwidth multiplexers. 192-GBaud QPSK and 160-GBaud 8QAM signals were successfully generated by using the 80-GHz frontend module based on in-house InP technology.
