Inphi announces a companion component to its 400G TIA, and now offers electronics to interface the latest 400G+ DSPs with coherent optics.

Single wavelength coherent 400G+ technology needs electronics that can support 16/64QAM modulation and challenging symbol rates of up to 64GBaud,” said Andrew Schmitt, founder and lead analyst at Cignal AI. “Inphi’s IN6417SZ is a critical component for enabling 400G coherent roadmaps at key customers who are focused on bringing next-generation of 400/600G line cards and pluggable modules to market as quickly as possible.
