Digital signal processing for short reach optical links

Digital signal processing enabled coherent 100/400Gbit/s transceivers for long-reach links. Short-reach (<;100km) links also demand 100/400Gbit/s but more stringent cost, size, and power consumption requirements need to be addressed. Potential modulation formats and signal processing methods are discussed.
