Mitsubishi Electric Develops 200Gbps (112Gbaud PAM4) EML Chip Supporting Four CWDM Signals
2023-03-05
Mitsubishi Electric Corporation (TOKYO: 6503) announced today that it has developed a 200Gbps (112Gbaud four-level pulse-amplitude modulation (PAM4)) electro-absorption modulator laser diode (EML) chip that doubles the speed of the company's existing 100Gbps EML chip thanks to a proprietary hybrid waveguide structure. Support for coarse wavelength division multiplexing (CWDM) of four wavelengths realizes 800Gbps transmission using four chips or 1.6Tbps using eight chips.
