Lightwave Editorial Director and Associate Publisher Stephen Hardy talks with Avi Shabtai, CEO of MultiPhy, the leading provider of silicon that supports 100-Gbps transmission using direct detection, rather than coherent detection. Shabtai offers his viewpoints on who the demand for 100G direct detect has evolved, whether the advent of metro-focused coherent 100G pluggable transceivers will threaten the market for direct-detect options, and whether there’s a future for direct detect at speeds greater than 100G.
