The RQ-100GD-CXXXX series 1 00G DWDM QSFP28 PAM4 CS Transceiver module is designed for use in optical data communications. 50nm as. They combine PAM4 modulation technology with DWDM (Dense Wavelength Division Multiplexing), achieving higher data transmission efficiency and longer transmission distances while maintaining the compact QSFP28 package. By combining four-level pulse amplitude modulation (PAM4) with dense wavelength division multiplexing (DWDM) technology, these transceivers enable. Fabrication of 53 Gb/s Optical Transceiver over 40-km transmission with PAM4 modulation.
