Heavy Reading launched its inaugural Coherent Optics Market Leadership Programin 2021 to investigate the opportunities and challenges in highest performance optics for 800Gbps and beyond and compact pluggable optics for 400Gbps. This 2022 edition builds on the foundations of the 2021 study and also investigates new ground as coherent optics evolves along the 400G trajectory and moves both upmarket (to coherent 800G) and downmarket (to coherent 100G pluggables).

This white paper is based on Heavy Reading’s 2022 Coherent Optics Survey results. It provides the industry’s most in-depth look at the current state and future trajectory of coherent optical transmission, covering the following:

• Architectures and applications, including the benefits and challenges in coherent IPoDWDM
• Features and requirements for 400G systems
• 400G optical transport services
• Coherent 800G embedded and pluggable optics
• Coherent 100G pluggable optics
