Mitsubishi Electric sampling wider-temperature-range CWDM 100Gbps (53Gbaud PAM4) EML chip for data centers

Tokyo-based Mitsubishi Electric Corp says that on 1 November it will begin shipping samples of its ML7CP70 100Gbps (53Gbaud) four-level pulse-amplitude modulation (PAM4) electro-absorption modulator (EML) laser diode chip for coarse wavelength division multiplexing (CWDM), which is expected to be applied in sets of four EML chips (emitting at wavelengths of 1271nm, 1291nm, 1311nm and 1331nm) as a light source in optical transceivers for 400Gbps optical fiber communication in data centers…
