Designing 100G optical connections

This post details the design and deployment of 100G single-mode optical transceivers for Meta's data centers, contributing to the Open Compute Project with the CWDM4-OCP specification. It addresses the challenges of upgrading data center networks to higher speeds while maintaining low power consumption and efficiency. Key contributions include optimizing transceiver specifications for data center environments (reduced reach, link budget, and temperature range), leveraging single-mode fiber for future-proofing, and collaborating with suppliers to achieve scale on schedule.
