Inphi bet big and bet early on linear drivers, rather than limiting drivers, for coherent applications. As a result they dominate this market. It announced a product refresh at ECOC 2016.

“Inphi is a leading supplier of drivers for optical modulators and is a critical supplier of technology to reduce the cost of metro coherent and non-coherent interfaces,” said Andrew Schmitt, founder and lead analyst at Cignal AI. “Devices such as the IN3217SZ enable the higher densities and lower cost solutions that are needed in coherent 100G and 200G applications today.”
