86 Gbit/s SiGe receiver module with high sensitivity for 160×86 Gbit/s DWDM system

A 86 Gbit/s SiGe receiver chip with an on-chip phase-locked loop and a preamplifier is presented. The chip is mounted and measured in a module assembly with RF-connectors. At the intended system data rate of 86 Gbit/s bit-error-free operation at a high input sensitivity of 50 mVpp is demonstrated. With an external clock, high-speed capability is proven by error-free operation up to 100 Gbit/s.
