The optical industry is at an inflection point as coherent innovation forks in two different but equally important directions: high-performance optics and coherent pluggables.

This Heavy Reading white paper, co-sponsored by Infinera, looks at the current state and future trajectory of coherent optical transmission, including architectures and applications, features and requirements for 400G systems, 400G optical transport services, coherent 800G embedded and pluggable optics, and coherent 100G pluggable optics.
