Inphi demos direct drive of Mitsubishi lasers
56Gbaud EML lasers directly driven by new CMOS DSP chip
Inphi, a developer of high-speed data movement interconnects, will demonstrate electrical-optical interoperability of its new Porrima Gen2 PAM4 platform solution at OFC 2019 in San Diego, CA March 4-7, 2019.
The demo will show optical link performance over single-mode fibre, featuring Inphi’s new Porrima Gen2 DSP with integrated laser drivers directly driving electro-absorption modulated laser diode (EML) lasers from Mitsubishi Electric.
According to the Inphi, this shows that a CMOS based DSP can drive EML optics directly at 56Gbaud. Traditionally in order to drive EML, a standalone non-CMOS modulator driver chip is needed to provide the required input voltage swing.
“We have developed high-performance EML technology and are prepared for the 400G market ramp. With the synergy between Porrima Gen2 DSP and our EML products, we are confident that we can deliver superior solutions to customers,” said Hiroshi Aruga, general manager of electro-optics technology department, IT R&D Centre at Mitsubishi Electric.
