Product Detail
AFR 40 GHz QPSK modulator design is based on a dual parallel structure of two Mach-Zehnder modulators (DP-MZM) embedded in a Mach Zehnder Super-Structure. Each internal modulator is designed to have EO bandwidth above 20 GHz. Monitor photodiode is provided for automatic bias control (ABC).
